Winslow in one instance, (e) Entero-peritonitis in one in¬ 
stance. 
Hence it is evident, from these statistics that, exclusive of 
the cases of occlusion of the bowel which one cannot expect 
to yield to any therapeutic treatment, the intra-venous in¬ 
jection of barium chloride will cure all cases of acute colic. 
The determination of the proper dose in each individual case 
presents no difficulty after one has had any experience with 
the method. 
An examination of the frequency and force of the sub- 
maxillarv pulse is the best guide. Should the heart show 
weakness or the pulse be weak and frequent, one-half the 
dose ordinarily given should only be employed. But even 
here in these small doses, barium chloride affords more relief 
and is a better carminative than any other remedy. In cal¬ 
culating the dose for intra-venous injections, one must calcu¬ 
late it in deci-grammes, the same rule applying as in the in¬ 
ternal administration. 
With such precautions in mind, the barium chloride treat¬ 
ment was inaugurated at D.’s clinic; no case of poisoning 
from the remedy has as yet materialized.— Berl. Thierarzt

The Function of the Muscular Coat of the Bladder 
in Normal Micturition. —G., in an experimental research, 
found that the vertical orifice of the bladder is normally 
opened by contraction of the unstriated muscular tunic, 
and that the contraction of this muscle is necessary to the 
expulsion of the urine. The contraction of the abdominal 
muscles may aid in this action, but it is not indispensable, 
and cannot replace it. 
Although volition seems to be directly concerned in the 
act of micturition, it acts rather by causing, through a psy¬ 
chic act, reflex contraction of the muscular coat of the blad¬ 
der. Ordinarily, the contraction of the muscular coat is the 
result of a reflex having its point of departure in a special 
sensibility of the bladder to tension, the two properties of 
the bladder, contractility and sensibility, being intimately re¬ 
lated, and being manifested in perfect accord in the physio¬ 
logical activity of the viscus.— Wochenschrift.
