one, either by percolation or digestion. It is, however, neces¬ 
sary that yon should be familiar with the appearance of the 
root. I have here an excellent specimen, which yon may 
examine. 
Liqnor ammonii acetatis (also known as Mindererns spirit) 
is a preparation which I hold in high estimation. It ought to 
be made fresh daily. The practitioner should make it himself^ 
which would be the only means he would have of knowing that 
it was freshly made. The process is a very simple one if litmus 
paper is used. A formnla which I have had excellent results 
from in lung affections, especially where there is much debility 
and high temperature, is as follows ;

As an adjunct with the former I give potassii nitratis and 
chloride of ammonia, of each one ounce, in a pail of water, al¬ 
lowing the animal to take six or eight swallows, every hour. 
Cantharides is an article of commerce extremely liable to 
adulteration, more especially in its powdered state. I have 
known it to have been supplied to the veterinarian adulterated 
30 per cent., the article used in its adulteration being brown 
mustard. The high price encourages this fraud. I make it a 
point to procure the flies in their natural state, and can thus 
judge for myself if they are fresh and free from being moth 
eaten, and can thereby depend on their vesicating properties. 
The powdering of the flies is a rather disagreeable process if 
precaution is not taken, but with proper precaution it is not 
disagreeable. I have here a very good specimen of cantharides, 
whole in their natural state. There are numerous formulas for 
making the fly blister as used by the practitioner. My experience 
is that the best results are obtained by using biniodide of mercury 
in conjunction with cantharides. I esteem biniodide of mercury 
as an absorbent. One drachm biniodide of mercury to one 
ounce of Bazilicnm ointment is probably one of the best absorb¬ 
ents for capped elbow, enlarged glands, or in dispelling or 
hastening the formation of pus. I have invented an absorbent 
which I have found sujierior to the former. It is hyd. bin- 
iodidi and potassae hydriodate, of each 3 i; aqua, 5 i. M. Sig. 
Apply with a tooth brush. This compound forms a clear and 
perfectly transparent solution. It acts like a charm in dispell¬ 
ing a curb. Just try it.
