pencil, ten models of horses’ teeth made from moulds that were 
obtained from living animals of the Cleveland bay breed, whose 
ages were matters of record ; they illustrated the changes in 
the teeth, from one year old upwards, besides seven other mod¬ 
els, all taken from accurate moulds of the original subjects, and 
illustrating various interesting features. 
The above exhibits were one and all prepared by students 
under my direction, assisted by a demonstrator. ^ 
In addition we had some ten or fifteen photographs illustra¬ 
ting veterinary work, and our facilities foi teaching it in a 
variety of ways. 
I heard that several other colleges had veterinary exhibits, 
but I did not see them, however, I was always so much engaged 
in various public ways when at the Fair that I found very little 
time to look around. 
When W. L. Williams describes the co-operative exhibit of 
the agricultural colleges and experiment stations, he says that 
there were Duzone models of horses teeth amongst other 
things, this of course was a mistake, but how it was made I 
cannot conceive, for each and every model had a label under it, 
and a large card was attached to the case stating that the mod¬ 
els were made by the students of the Michigan Agricultural 
College, they were duplicates of the ones already mentioned in 
the other exhibit which I was responsible for (our boys should 
feel rather flattered when they learn that their work was mis¬ 
taken for that of the far-famed French firm). 
The half dozen actinomycotic jaws of cattle, etc., appear to 
have been treated in the same way as the teeth, and the labels 
were overlooked. They were prepared by Prof. Mayo of the 
Kansas Experiment Station, and certainly illustrated many 
features of this much-talked of disease in a very interesting and 
scientific manner. I also thought the pathological specimens 
contributed by Prof. Hinebauch, of the North Dakota Experi¬ 
ment Station, illustrated the points they were intended to, and 
that they were valuable specimens. The other articles mentioned 
were there, as were also some others not noticed by Williams ,
