Gentlemen, here are the three teeth which Mr. Parks has re¬ 
ceived, as being those pf his horse, and which he. has had the 
kindness to lend me for this occasion. Dr. Miller, who has had 
them in his possession, sent them himself to the owner, and will 
assert that they are the originals, notwithstanding the denial 
made by those who may have an interest in concealing the truth, 
and no doubt by your examination you will certainly acknowledge 
that none of these are diseased sufficiently to justify their 
removal, that none of them are diseased enough to have pro¬ 
duced all the trouble; in fact, two of them, you will notice, are 
perfectly healthy, and one has but two little insignificant spots of 
decay, of the size of the head of a small pin. 
Were these the result of disease of the dental pulp, as Vir¬ 
chow says, the matrix of the tumor, I leave it to you to say, but 
certainly you will all acknowledge that if I have not succeeded 
in pointing out a cause for osteo sarcoma, I have shown you that 
there is one thing important which veterinary schools must place 
in their curriculum, and that is a course of Veterinary Ethics.

As much has already been published on this cause celebre , and as 
the poor horse died at Goshen on the 22d instant, we will not say 
any more on the subject, except to give the result of the post 
mortem examination, which we made some twenty-four hours after 
death, and which will appear in our next issue. 
When we were called to give our opinion about the condition 
of the horse, in May last, and after our opinion had been given 
in writing to his owner, we received a letter from Dr. Gadsden 
of Philadelphia, to which we answered. Both of these letters 
appear in this issue of the Review. We will be pleased now to
