first three molars are most prone on account of the unusual 
physiological changes taking place; here I think many times the 
unshed primitive tooth produces much trouble with the succeed¬ 
ing permanent one. These conditions can sometimes be intelli¬ 
gently explained and other times difficult. I have a subject here 
I think worthy of relating, from the fact that it was a case of 
constitutional trouble, no doubt. Black filly, Evening Star 
Standard, by Count Wilkes; bred at Pen Valley Stud, Morris V. 
Pen; sold in Chicago to Mr. T. J. Vielder of my town. Soon 
after her arrival I saw her and noted the following symptoms: 
large bulging appearance over both superior maxillaries, about 
2x5 inches; masticated her hay badly; also her grain if given 
whole, poorly; this was January, 1893. 
The patient being only about 22 months old, it was not 
deemed wise to extract the primitive teeth, but after being some¬ 
what conservative for some time and seeing no improvment we 
extracted first two molars and later on the other four which spec¬ 
ulum showed were adhered to maxillary. After this for a time 
improvement was manifest; then I found the first molar making 
its appearance, but shortly after the tooth was found to be 
carious and advised its removal, but owner here being persuaded 
to change doctors, did so, to my surprise and chagrin. 
Consequently I had no further interest in her until the next 
September, when she was led to the hospital an object of 
beauty to say the least, a large opening over each sub-maxil- 
iary with an enlargement the size of a goose egg on each. After 
several days of restorative treatment, we went in on one side, 
some one having removed most of it, and as she could stand the 
work from time to time, until delivered of the first two molars 
and a large piece of maxillary. Under rigid antiseptic treatment 
all healed nicely and patient is now driving every day. 
In this case you will observe the teeth were never fully de¬ 
veloped; you will also observe a large deposit of cementum upon 
the roots of primitive, and at time of removal of primitive molars 
no pulp was to be seen and tooth was all split in fragments on 
account of blood supply being cutting off. (See William’s Surg.
