difficulty, injected 11 litres of water with a pressure of 80 cm. 
into the intestinal tract. The water flowed from the mouth. 
The experiment succeeded in animals. Some time afterward, 
i the author treated a dog much emaciated as a result of a 
i profuse diarrhoea. The whole intestinal tract was irrigated 
with a solution of lactic acid, io to 1000. The experiment 
succeeded, and 7 litres of the solution issued from the mouth. 
The diarrhoea ceased. In the same way the author 
achieved success in uncontrollable diarrhoea of children, foetid 
diarrhoea in typhus, of icterus catarrhalis, etc. 
In a patient suffering from emaciation and diarrhoea with¬ 
out any assignable causes, the irrigation brought to light an 
entire taenia. All disturbances ceased with the aid of anti¬ 
septics, the whole intestinal tract being rendered sterile. To 
prevent regurgitation of fluid, from the intestine into the 
rrigator, the author has constructed a special apparatus.

NEPHRORRHAPY IN A DOG. 
The presence of calculi in the pelvis of the kidney necessi- 
ated until now in human surgery the total extirpation of 
he affected organ. 
This extirpation is necessary where too large and too 
mmerous calculi have caused too great a structural change in 
he kidney substance proper. Cases of calculi in the pelvis 
>f the kidney can occur, in which the kidneys are unchanged 
er se, in which cases extirpation is distinctly contraindicated; 
ere, instead of extirpating the kidney itself, you enter the 
elvis of the organ to remove the calculi. 
This incision into the pelvis, simple as it is, gives rise too 
ften to very dangerous fistulas; hence, cutting through the 
diole length of the kidney substance, into the pelvis, and 
smoving the calculus by this route appeals to one’s judg- 
lent. Further, there is less hasmorrhage than one would 
xpect in such a vascular organ as the kidney. The first 
peration of this kind, was performed by Prof. Lorge in 1890, 
ith the assistance of the author, who operated successfully 
pon other dogs since. The animal is chloroformed, the flank 
laved and disinfected.
