ground her teeth at intervals, and the coina became more and 
more marked. Soon the eyes became fixed, dull, and lustre¬ 
less ; the temperature 37° respiration stertorous, faeces in the 
rectum small, very hard, and dark. On inquiry, I was told that 
she had had a calf five and a-half months previous. I, there¬ 
fore, concluded that in all probability I had some trouble of the 
alimentary canal to deal with, and I administered a powder of 
aloin four and one-half drachms, gave clysters, and catheterized 
the bladder. Before leaving she became tympanitic, and I 
tapped her, and left my trocar and canula with the owner, with 
instructions how to use it. I also showed him how to prop the 
cow in case she got over on her side. Thai: night I found no 
chano-e in my patient ; I had a powder .of pot. iod., 3 iij, in ray 
case, and thought I would try it, so I dissolved it in about half 
a pint of water and gave it per orem. Her breathing was then 
very labored, her look blank, and no reaction on. touching the 
eyeball. Seven hours after receiving the solution she arose.. 
Whether this was a case of parturient paresis or not I. cannot 
say 5 I only know, after having had a good deal of experience in 
the treatment of cattle, I was unable to distinguish between this 
disease and the many cases of milk fever that I have, met with. 
In conclusion I wish it to be understood that I in no way 
wish to depreciate the work that Mr. Schmidt has done to clear, 
up the mysteries hanging around this disease, but that I want 
to have more light thrown on these two points that I have 
brought before you, namely : as to why we administer the 
. iodide of potash by way of the mammary glands, and can this 
disease have its origin in an abnormal secretion of colostrum 
when we can meet with this disease so long after colostrum has 
formed in the mammary glands. P. D. Bray, Veterinarian.

Editors American Veterinary Review : 
Dear Sirs:— On page 296, July Revifw, in your reply to 
Dr. Abbott you suggest hearing from other practitioners in re- 
gard to the action of cocaine. 
I have experienced the same results in several cases.. Oae 
in particular being a mule, and in another a trotting gelding, it 
seemed to produce great excitement and hypeisesthesia o\er tie 
field of injection. I, however, use only a 4 per cent, solution 
and find just as satisfactory results in locating lameness or ior 
firing, nerving, etc., as with the stronger solution. 
Very truly yours, J. R. Mitchell.
