remors, shivering - , coldness of the limbs, pallor of the mucous 
nembranes, quickened, difficult, and rattling respiration, tu- 
nultuous beating of the heart, and considerable elevation of 
he rectal temperature. 
To sum up, colics, which have their origin in disturbance 
»f the circulation, have no particular signs which would allow 
hem to be distinguished with sufficient precision in the Com¬ 
dex group of abdominal complaints. 
During the series of years that I have been in practice? 
he subject and treatment of colic in horses has been most 
nsatisfactory to me, and the literature of our text books 
rould not satisfactorily come to my aid. Why, I have often 
sked myself, do horses become subjects of colic? Why do 
hey, as a rule, become more severe until the last when they 
ie ? Why is it that the usual stereotyped colic drench or 
olus will relieve, and then again it does not produce any im- 
ression whatever, apparently ? Why is it that a case of colic 
ecovers without any notice being taken of it ? 
Knowing that there is never an effect without a cause, I 
egan to make my post-mortem examinations with more care, 
nd open some of the leaves of the book of nature that I had 
een in the habit of passing over. The result of this closer 
bservation revealed to me the fact that the vessels supply- 
lg the intestines with blood were frequently abnormal and 
lowed aneurisms. Opening these dilations, I found para¬ 
des, nematodes, and, by referring to Cobbold, found that 
ley were well known. 
The question then presented itself to my mind, are we, as 
body of practitioners, less observing than those gone before 
i? Do we look wise, give a decided opinion upon some 
rery-day occurrence in practice with the positiveness as 
robably has been done in colics, and know as little about the 
arise and lesions produced ? Are we not, as a body of veteri- 
arians, more inclined to open the book of charges than that 
f nature ? Do not think for a moment that I would in the 
:ast underrate the worth, or honesty of, the members of this 
rofession. I think the fault lies, if there is any, with the 
athors of our standard works. In this particular instance the
