Preface

Tlie author caused to be publislied in 1900 a l)ooklet entitled: " A Course in Surgical Operations by W. Pfeiffer and W. L. Williams." consisting of an authorized translation of Dr. Pfeiffer's Operations-Cursus with such changes, omissions and additions as were deemed desirable. Three years of constant use, with such criticisms as have come to the author from others, have .served to point out desirable changes of so sweeping a character as to demand a practically new treatise and to render the continuance of a formal joint authorship inexpedient. The author has drawn freely upon Dr. Pfeiffer's Operations-Cursus in the preparation of the text which in many chapters is practically copied therefrom, including the illustrations, and gratefully acknowledges his profound obligations thereto. On the other hand nothing has been copied or extracted except it could be freely adopted as the author's own view, releasing Dr. Pfeiffer from all responsibility for the character of any of the contents.

The volume is primarily designed for the use of the author's classes in laboratory surgery and embryotomy in which the student performs the surgical operations described, on animals procured for the express purpo.se, under chloroform anaesthesia whenever possible, after which the subject is destroyed while still anaesthetized ; at the .same time it has been aimed to render the volume of the greatest possible value to the practitioner consistent with this plan. The operations included under this .scheme are necessarily limited to those which can be reasonably well performed on comparatively sound animals of little value and regularly procurable for laboratory purposes. The ii.st covers a wide range and is designed to give to the student as thorough training as is practicable in a laboratory course and includes w-ell nigh all the more important varieties of confinement, anaesthesia, di.sinfection, sutures, bandaging, dre.s.sing and other adjuncts to operative work. The chapter on trephiniv PREFACE.

ing of the facial sinuses has been dealt with at length in order to fully and clearl}^ describe the author's method of operating ; a new operation for poll evil has been inserted and there has been included a description of some of the most important embryotomy operations as they are carried out in the laboratory by means of freshly killed, new. born calves which are placed in the position desired, in the artificial uterus of a specially prepared skeleton.

Generally but one method of operating is described, the one chosen being that which in the author's experience has proven the most valuable in actual practice, and no operation has been introduced purely for practice but each one has been tested and known to have practical value.

Where two methods of operating are given, the^^ are inserted because each has definite points of superiority over the other and one method may be specially applicable in a given case, another in a different patient where the same operation is to be performed as for example, a milk cow is best spayed through the vagina while a heifer must be operated on by an incision through the abdominal walls.

Considerable stress has been laid upon the surgical anatomy of the parts involved in each operation ; some uses of the various operations are mentioned ; some of the chief dangers of each are pointed out and in some cases references to literature upon the operation or the diseases for which the operation is designed, are cited.

The figures in the text except Nos, 5, 10 and 11, and the Plates Nos. I, II, VIII, X, XII, XIV, XVII, XVIII, XXI, XXII, XXIII, XXV, XXVIII and XXIX are from Dr. Pfeiffer's Operations-Cursus ; Plate No. Ill was drawn by Dr. C. F. Flocken, Bureau of Animal Industry, Washington, D. C, and the remaining Plates were drawn under the direction of the author by Mr. C. W. Furlong, Instructor in Industrial Drawing and Art in Sibley College, Cornell University.
