A CLINICAL STUDY OF 0D0NT0MES. 
By W. L. Williams, Y.S., Bloomington, Ill. 
(A Paper read at the Annual Meeting of the Iowa State Veterinary Medical Association). 
Fig - . 3 b represents the last inferior molar from a small 
four year horse, affected some two years, and having an ex¬ 
ternal fistulous opening without great enlargement of maxilla. 
The tooth was trephined down upon and readily dislodged 
with the punch, but the assistant who was looking after the 
tooth inside the mouth allowed it to slip from his grasp and 
it was instantly in the pharynx, and on its road down the 
oesophagus, lodging at the middle region of the neck. Fear¬ 
ing that the tooth was sharp and jagged, we did not attempt 
to push it into the stomach nor even allow the animal to swal¬ 
low it further, but immediately cut down upon and removed 
it, from an indirect result of which the animal eventually 
died. 
The case represented in Figs 8, 9, and 10 is of unusual in¬ 
terest in several respects, the odontome being of unusual in¬ 
terest, and the checkered career of the animal fitly illustrating 
the vicissitudes through which a curable animal may pass. 
The patient was an aged brown gelding knowncas Chester 
B, with a pacing record of 2:28^. 
The earliest trace we have of this horse was about 1887 
or 1888, when he was owned by Dr. Sutherland, V. S., 
of Sutherland and Benjamin, breeders of trotting horses 
at Saginaw, Mich., at which time, when six or seven years old, 
he appears to have been sound but, according to Dr. Suther¬ 
land, was a “puller.” 
We next learn of him in the hands of a Mr. Long, of same 
city, by whom he was traded to Mr. O. Woodworth of 
Bloomington, Ill., before the latter had seen him. 
The exchange appears to have been consummated by cor¬ 
respondence and largely upon the professional opinion of Drs.
