Preface

Several years have elapsed since the Author's attention was first directed to the subject of Milk, as an article of human sustenance in large cities. (He had observed, with regret, that in the management of the dairies, no regard was paid to the peculiarities of the animal organization, and a little reflection convinced him that consequences of an injurious kind, might be expected to result from this unnatural treatment.^ Desiring to ascertain whether such were its recognized effects, he had recourse to books ; but, to his surprise, could discover nothing that had been written upon the subject. As the facts involved various consequences affecting the physical welfare and incidentally the morals of the people, he supposed they might be obtained from physicians or other men of observation and intelligence ; but after extensive oral intercourse for information, he found that the subject, wherever introduced, was previously unthought of and unknown. It appeared, in short, that whatever relation it sustained to the well-being of the community, remained yet to be developed and published to the world.

Being thus urged to a personal investigation of the subject, he entered upon a careful survey of the dairies, and their appendages the distilleries. The latter he found surrounded with hundreds, and in some instances, with thousands of milch cows, confined in filthy pens, bloated, diseased and dying, and most

20 PREFACE.

inhumanly condemned to subsist chiefly on the dregs of distillation, reeking hot from the whisky manufactories. He followed the distribution of the milk as it flowed from these polluted sources to his own family, where he beheld his youngest child rapidly sinking under the effects of this pernicious aliment, whilst the cause of the illness, until then, was unknown 'and unsuspected. Enlarging his survey, he ascertained that in this community alone there was more than sixty thousand families, and in these families more than twenty-five thousand children under the age of five years, among whom this impure milk was a staple article of diet.

He next examined the bills of mortality in some of the chief cities, extending back his researches as far as authentic data could be obtained, and discovered, that from some cause or causes unknown, the proportion of infant deaths was not only frightfully great, but steadily augmenting. From the year 1814 to 1841, the destruction of infant life had increased from about thirty -two per cent., to more than fifty per cent. ; in other words, more than one half of the total deaths, occurred among children under the age of five years. This appalling fact, led him to examine the vital statistics of foreign cities, to ascertain to what extent this fatality was general and inseparable from the conditions of a city life ; and he learned that in them it was less and diminishing, whilst the reverse was true of our American cities.

He then traced the much abused cattle, which in a few months become so diseased as to be ever after unfit for the dairy, to the shambles, where they are slaughtered by thousands ; and to the markets, where the flesh is sold at enormous prices to be eaten by our citizens. He ascertained, moreover, that the breweries and distilleries, in this way, were destroying nearly as much grain created for purposes of sustenance, as would suffice for

PREFACE. 21

the consumption of the population. And to crown the whole, this vast and complicated system, with its wide-spread mischiefs, was produced and sustained by agencies the least likely to he suspected ; it was, in short, so involved and ramified, that the people were unconsciously a party in bringing upon themselves the evils they suffered.

Having satisfied himself that these facts were indisputable, it became his immediate object to spread them before the public in a series of essays which appeared in the public journals, and subsequently by numerous lectures. For a season, the evil was arrested, several pure dairies sprang up, and many philanthropic individuals became interested in the subject. But it had by a growth of many years struck deep its roots, and acquired an amplitude and strength which resisted the puny efforts that were brought against it. The voice of the lecturer was heard by comparatively few, and soon forgotten ; and the leaves of a public journal for reference, were scarcely less precarious and fugitive. The Author was thus, unfortunately, the chief depositary of facts on the subject, which drew on him from various quarters applications for information, utterly beyond his ability to supply. Those, consequently, who from a knowledge of general principles were eager to aid in their diffusion for the benefit of others, were deterred from engaging in the work, because unfurnished with the facts which were essential as a basis of all just reasoning upon the subject. In other departments of benevolent action, the materials were at hand ; but in this they were so far asunder as to discourage ordinary effort to bring them together for practical effect. There was not, in brief, a page of written authority that could be consulted.

These circumstances explain the origin of this volume. It was undertaken to supply an urgent demand for information on an important, economical and moral subject, hitherto untouched

22 PREFACE.

by any previous writer. In directing his attention to the plan of a work for this object, other topics connected with it, besides those mentioned, naturally presented their claims to consideration as branches of the subject, and necessary in a general history. He was. therefore, induced to take a wider range than was originally designed ; and by thus treating it in a manner never before attempted, has rendered the work, he trusts, more complete and deserving of attention, than it would otherwise have appeared.

In the historical part, as the limits of the essay did not admit of detail, he has introduced only the best, authenticated incidents and particulars, which were scattered through a varietyof unconnected departments of literature ; and endeavored to bring them into such succession and arrangement, as, whilst they illustrate the general subject, and instruct and interest the observer of nature, will, by the manifested evidences of design everywhere luminously displayed, naturally elevate the devout mind to communion with him, without whom was not any thing made that was made.

The scientific branch of the iniquiry he has endeavored to render as complete, as the present knowledge of the subject will admit. For this purpose the best and latest authorities have been consulted, including the most recent experiments and examinations. Hence the results which philosophical chemistry has developed of the elements of milk, their proportions and combinations, and the methods of obtaining them, may here be learned by the professional student; and the man in ordinary life who is not a practical chemist, and is without the convenience of a laboratory, may also gather such instruction as will, by easy experiments, protect his health and wealth from fraudulent impositions and injury. To the deductions of others, the Author's

PREFACE. 23

acquaintance with the suhjecthas enabled him to add some experiments of his own, with such practical hints and elucidations, as, he believes, will be useful and profitable. The arrangement of the matter is new, and elaborated with the design of condensing into small compass, the sum of what is now known on the subject.

The essay does not pretend to the character of a systematic guide to the dairyman ; yet it contains valuable practical instructions on the subject, which, it is believed, will repay a perusal by persons engaged in such occupations. By an observance of the principles laid down, many serious mistakes, common in dairy management, will be avoided.

In the prosecution of the work, it has been his design, in every instance, to acknowledge his obligations to the authors he has consulted, and he is not aware of having deviated from this purpose. If, however, he has introduced any sentiment or expression without referring it to the writer, he trusts this general acknowledgment will atone for the inadvertence.

Having no other than a moral interest in the subject, it has been the author's object to exhibit facts, solely with reference to humane and benevolent results. In doing this, he has been anxious to avoid all reasonable occasions of displeasure to any class of men. If he has done injustice to any, it has been undesigned, and when made known, the acknowledgment shall be as public as the offence. If, however, in the discussion of the subjects that have come under review, some truths are brought to light which strongly reflect on the practices of those engaged in them, for this he is not morally amenable ; and the odium and the guilt must rest upon those who, with better knowledge, pursue occupations that are disreputable in themselves, and injurious to their fellow men.

PREFACE.

As the work has been written amidst the pressure of other employments little congenial to literary pursuits, the Author is not so presumptuous as to imagine that it is free from those inaccuracies and defects, which under any circumstances are usually inseparable from a first attempt to sketch a new subject. He has, indeed, painful apprehensions, lest its imperfections materially impair its usefulness. Beyond this his solicitude does not extend. But should the result disappoint his fears, and this unpretending essay become instrumental, to any extent, in vanquishing the evils he has endeavored to portray, the philanthropic will rejoice in its success, and his labor receive an abundant recompense.

Chapter I. Introduction

Milk, derivation of the term. — Its peculiar properties and characteristics. — Primary design of. — Providence of successive nature: — Importance of the study. — Mutual dependence of the animal and vegetable kingdoms. — Parts of the system essential to the whole. — Evidences of design in creation. — Material things subservient to a moral purpose. — Tendencies of these considerations.

Milk, from the Greek Mel-ysiv, or the Latin Mulgeo, which literally signifies to press out by handling or softening with the hand, is the name of a well known animal fluid. It is the only material in the whole range of organic matter, that is designed and prepared by nature, expressly as food. Being a natural compound of albumen,* oil and sugar, which constitute the three great staminal principles that are essential to the support of animal life, it is a model of what a nutricious substance ought to be, and the most perfect of all elementary aliments.f Such being its characteristics, it possesses both animal and vegetable properties, and naturally takes its place at the head of nutrient substances. As it cannot be imitated by art, it occupies a

* The principles fibrin and albumen, which play so important a part in the constitution of the animal solids, are now, on the authority of Liebeg, stated to be identical. M.Dennis has communicated a letter to the Academy of Sciences, in which Liebeg states that he has been able to dissolve fibrin by a moderate heat in a saturated solution of nitre, and that the fluid has all the properties of a solution of albumen. — Provincial Medical and Surgical Journal.

26 PRIMARY DESIGN OF MILK.

place among aliments which nothing else can supply. It is, indeed, made essential by Infinite Wisdom to the existence not only of the human family, but also to many most useful orders of animals, to which man, notwithstanding his higher attributes, in physical organization, is nearly allied.

Milk was primarily designed to nourish the young of certain species of animals, during the early stages of their existence ; its use, of course, as food, has been coeval with their creation. But as its nourishing properties and adaptation to the wants of man could not long have escaped his observation, it is not reasonable to infer that he who was the divinely appointed lord of irrational creatures, would hesitate to appropriate this unlabored gift of nature to his own use. And as this subservience of the creatures to the necessities and comforts of man, secured from him in return that protection which would tend to augment their numbers and increase their enjoyments, we may not doubt, that in this way, the beneficent intentions of the Creator were best fulfilled.

But, important as is the part which milk sustains in the animal economy, its history has never been written. Yet who will affirm that the subject, either in itself or in its relations, is devoid of interest and useful instruction ? We refer not now solely to the fluid aliment which is of the highest economical value to man; nor yet to the lacteal system, which has been denominated a constant wonder ; but chiefly to the providence of successive nature in the animal kingdom, which from the remotest antiquity has preserved for the use of mankind so valuable a class as the mammiferous domesticated animals from extinction. If the humblest production of the Creator deserves the consideration of the philosophical naturalist, much more should

the mass of mankind regard with interest an order of quadrupeds with which they have the nearest connection, and from whom the advantages derived are so important, that man with all his moral and mental endowments, has never yet attained a state of civilization without their subjugation. To enter, however, into an exposition of this department of zoological science, would be as foreign to our object as superfluous in itself, for it has already been a subject of careful investigation by others. But there is one view, which, so far as we are informed, has not been given by any writer. We refer to the distinction which has been assigned the bovine tribes in history, from the infancy of human society. The ox and his kind have followed man in all his migrations. There is scarcely a country in which they are not either indigenous or naturalized. And as in this we discover the wisdom and benevolence of a designing Providence strikingly illustrated, it is proposed to throw together a few proofs of the fact, as we find them scattered in the records of past ages. This, we conceive, will furnish a profitable subject of contemplation, and, perhaps, not inappropriately introduce the volume to the reader.

It may here, however, be preliminarily remarked, that means with reference to ends are everywhere manifested in the endless diversities of inanimate matter — also in the orders and gradations of animated beings, which appear reciprocally dependent and necessary to each other. An illustration of this principle, as manifested in the relation of the animal part and the vegetable part of the creation to each other through the medium of the atmosphere, is thus expressed by Mr. Madison : " It seems now to be well understood, that the atmosphere when respired by animals, becomes unfitted for their further use, and fitted for the absorption of vegetables ; and that when evolved by the latter,

it is unfitted for the respiration of the former: an interchange being thus kept up, by which the breath of life is received by each in a wholesome state, and in return for it an unwholesome one. May it not be concluded from this admirable arrangement and beautiful feature in nature, that if the whole class of animals were extinguished, the use of the atmosphere by the vegetable class alone, would exhaust it of its life-supporting power : that, in like manner, if the whole class of vegetables were extinguished, the use of it by the animal class alone would deprive it of its fitness for their support 1"
