I believe the barium is uncalled for and only increases the un¬ 
easiness and suffering for no particular good. Owing to the 
exceedingly energetic action of the drug on the bowel, I am sure 
its use would only be hazardous while tympanites is present to 
any great extent. 
Always use the trocar and canula before making the injec¬ 
tion if the abdomen is distended by gaseous formation. In ad¬ 
ministering the barium, dissolve a dose of the salts (say 15 grs.) in 
not less than one-half ounce of pure water, and make the injec¬ 
tion with the solution at a temperature of 100 degrees F. The 
jugular vein may be easily raised by pressure upon it with the 
fingers of the left hand ; the needle may then be introduced 
with the right. If the needle is properly introduced, blood will 
escape from the vein through it, and the injection may then be 
made without further trouble. My experience has also taught 
me to desist from the use of barium in all cases where there is 
regurgitation. Better take a little more time and overcome that 
condition by antiseptic treatment; then resort to the use of the 
barium if necessary, and the effect will be exceedingly gratifying. 
ODONTOMES: REPORT OF THREE CASES. 
By J. F. Pease, D.V.S., Quincy, III. 
A Paper read before the Illinois State Veterinary Medical Association, Feb. 17, 1897. 
In Vol. XV. of the American Veterinary Review occurs 
^n article from the pen of Dr. W. L. Williams, upon the “ Clin¬ 
ical Study of Odontomes.” In this he quotes the classification 
of Dr. Sutton, which, at the time the above article was pub¬ 
lished, was the first of the kind to come to my notice. 
With this able study by my worthy preceptor. Dr. Williams, 
before me, I shall describe three cases occurring in my practice, 
and, with some misgivings, attempt to classify them. 
Cases /. and II, were undoubtedly fibrinous odontomes, but 
whether to consider them as aberrations of the follicle or of the 
papilla, I am undecided. 
Case /. was a sorrel road-mare, aged 13 years, observed to
