EXTRACTS FROM EXCHANGES.

subcutaneously in the region of the scapula. On the average,, 
after ^ to i minute, twitchings of the jaws set in, but not 
so prominently as in the first set of experiments. Then a period 
of disquiet, followed by severe colicky pains, set in. They 
reared and stamped, shook their heads,* and contracted their 
upper lips. One rolled about the floor, one perspired profusely. 
The discharges were not so profuse as in the first set of experi¬ 
ments, only occurring i, 2, 3, 3, 6, 6 times respectively during 
the observations. The pulse increased from 46 to 56. Respira¬ 
tion and temperature remained normal. Whether the continued 
rearings of the animals and their continuous colicky symptoms, 
which became most severe from 15 to 20 minutes after the 
injection, were really due to intestinal pains—the peristalsis was 
increased in most cases—is not quite certain. The fact is that 
the horses always stamped or moved most uneasily those limbs 
near the site of injection and that they tried either to protect or 
gnaw at the site of injection. Although neither swelling, pain 
nor heat was evident at the site of injection, still the site of in¬ 
jection seemed to be painful. The disquiet lasted 1 ]/ 2 hours 
upon the average, some only returning to their normal condition 
after 2 hours. No local sequelae developed at the site of in¬ 
jection. Compared with the intravenous injections, the subcu¬ 
taneous injections were very unsatisfactory. It is true, the 
catharsis ensued, but the general symptoms of disquiet, and 
especially the abdominal pains and apparent local tenderness at 
the site of injection, form such a congerie of symptoms as would 
give the laity the impression that one was increasing instead of 
diminishing the colic. It is true, that such a consideration 
should not enter in the treatment of disease, but if the same 
effect can be induced in a more satisfactory way, why not em¬ 
ploy that way ? The author, therefore, prefers intravenous in¬ 
jection, inasmuch as it is not more difficult than the other, is 
prompter, and causes less disagreeable concomitant disturbances 
than the subcutaneous injection does. With asepsis, no risk is 
run. Where the excitement of intestinal peristalsis for the pur¬ 
pose of emptying the bowel is required, as in the case of hard 
seybalse of faeces, in colic or intestinal paresi associated with 
colic, where formerly eserin and pilocarpine were used, the 
cheaper remedy is Ba Cl 2 given intravenously. It has in the 
hands of the author shortened the period of colic, in varions 
cases. Where the pulse is rapid (70 to 80 to the minute), 
or where you fear obstruction, Ba Cl 2 is contraindicated, 
inasmuch as it does no good and increases the pain needlessly*
