REPORT OF THE PROFESSOR OF VETERINARY SCIENCE. 39 



Board of Agriculture to do so, I proceeded with the work. I at once 

 placed myself in communication with the twenty-six veterinarians who had 

 charge of the veterinary departments in the colleges and stations, and 

 arranged with some of them for an exhibit intended to show: 1st, that 

 veterinary science has its place in many of the agricultural colleges and 

 experiment stations of the country; 2d, something of the character and 

 scope of the instruction and work done; 3d, illustrations and samples of 

 material or facilities in models, books, pathological specimens and instru- 

 ments, used as aids in giving instruction or doing practical work; 4th, 

 specimens of work done by students; 5th, specimens derived from experi- 

 mental work. 



Our college contributed towards this exhibit: One dissected horse, a 

 number of models made by students of horses' teeth, taken in most 

 instances from living animals, and intended to show the changes which 

 take place in them from yearlings to advanced age; also a number of 

 photographs illustrating various interesting features in connection with 

 veterinary work in this college. 



Besides taking charge of the veterinary alcove of the cooperative college 

 and station exhibit, I was requested to prepare one to be shown with our 

 college exhibit in the Liberal Arts building, and to make it possible forme 

 to get them both ready in the short space of time left for the work, I was 

 permitted to engage B. O. Johnson, D. V. S., a former student of our col- 

 lege, to assist with it. Of his faithful efforts, I can hardly speak too highly. 

 Not only did he direct the students under him in an agreeable and profit- 

 able manner, but he did a large share of the manual part of the work, 

 which consisted in the preparation of natural skeletons of the horse, cow, 

 sheep and hog. It may not be out of place for me to say here that a nat- 

 ural skeleton is one in which the individual bones are held together by 

 their natural ligaments, and not by wires or artificial ligaments, as is the 

 case with the ordinary skeleton of commerce. To clean the bones of the 

 former variety, in a presentable manner, requires much patience and time 

 to hand pick them thoroughly. The bones of the artificial skeleton are 

 cleaned by boiling, comparatively speaking a much easier process, but I do 

 not think they make as interesting a specimen when mounted as the 

 natural kind. 



Besides the above skeletons we mounted two dissected horses, showing 

 the deep seated muscles on one side, and the superficial ones on the other, 

 we also took pains to dissect out ligaments affected in such diseases as 

 curb, bog spavin, sprained fetlock, as well as parts affected in sweany, 

 laminitis or chest found; coffin joint lameness, and many others not so 

 often noticed. A great disappointment occurred with these horses 

 through the work of installation being delayed at the fair, owing to the 

 crowded condition of all freight departments, and the space in one building 

 not being ready, they were exposed to the damp and mouldy atmosphere 

 of Jackson Park for so long a time that they became mouldy to such an 

 extent that they were practically ruined. 



We also prepared models of horses' teeth in plaster of Paris, similar to 

 those in the cooperative exhibit, and had another set of photographs 

 developed. 



The work of preparing these exhibits was done to a large extent during 

 the long vacation and first half of the spring term. The class room 

 work during the first two terms of 1893 was directed towards a description 

 of the diseases of the domestic animals. Twenty-four lectures were given
