EXTRACTS FROM EXCHANGES. 
the two, the symptoms were all milder and disappeared entirely 
after an hour. The urine was upon the following day of dark 
color, faeces similar to first case. The exudation from the cuta¬ 
neous vessels was absent, and notwithstanding the evidently 
milder action upon the skin, the lesions healed much slower 
than in the former ease. The particular reason for this poison¬ 
ing can only lie in a too concentrated mixture. There was no 
acetic acid used in washing and the rubbing was not excessive.

Note.—T hese cases so carefully noted are of importance, and from several points of 
consideration. The prevailing opinion among practicing surgeons that creoline is a safe 
antiseptic has led to a very careless application of the same. While it is comparatively safe 
as compared with agents like carbolic acid, still its properties and possible impurities should 
never be lost sight of. There are several questions in the above reports, as the propriety of 
its application in such form, in such case? Purity of drug? Does it undergo change on 
exposure to the air ? Idiosyncrasy ? Treatment, etc. ? F. H. M. 
AMERICAN REVIEW. 
Embolism of the Aorta. —Dr. Noack, of Reading, Pa., re¬ 
ports an interesting case of this nature occurring in a mare, in the 
April Journal of Comp. Med., the location of the embolus being 
in the posterior aorta, just back of the renal arteries and extending 
into the femorals, and causing enormous enlargement of the heart 
(it weighing 23 ^ pounds), the cardiac muscles being especially 
strong, along with enlargement of the liver, spleen, and kidneys. 
The following interesting symptoms were displayed by the ani¬ 
mal just before being destroyed for the autopsy : The owner 
gave the history that whenever the mare was driven she would 
sweat profusely, walk lame, and then begin to stagger. A physical 
examination of the patient standing showed the mucous mem¬ 
branes of the eyes and nose very pale, beating of the heart feeble, 
and regurgitation of the blood into the heart could be heard. The 
heart sounds were irregular and scarcely audible ; pulse feeble, 
but could be distinctly felt. The horse was then hitched to a 
buggy to see the symptoms when driven. She trotted the first 
four blocks all right, then suddenly the tail got stiff and twisted 
in a peculiar manner ; she ceased trotting, and walked as though 
the muscles of her hind legs were in cramps. These symptoms 
disappeared in a few minutes, beginning to walk again, sweating 
profusely, but the hind part staggered so much that she was 
halted. Breathing was very difficult and accelerated; head, 
fore, and middle part of the body being covered with perspira¬ 
tion ; not a drop of sweat on the hind part, which was evidence
