matures which made the intravenous and his old method un- 
esirable. His principle is to use a hollow needle in remov- 
ig the blood, and a second needle to inject the same directly 
ito the vein of the recipient. The fundamental element of 
iccess in the application of this procedure is an aseptic con- 
ition of the instruments, skin of the patient and hands of the 
perator. Narcosis is necessary in order that the vein may» 
e exposed and the needle introduced without permitting, 
ontemporaneously, the admission of air.— Munch, med. Woch. 
HEALING OF FISTULA BY OLEUM TEREBINTHINiE. 
Most veterinarians appreciate with what great difficulty 
le healing of fistulous tracts is accomplished, in many in- 
ances, especially when occurring in places that are distant 
om one’s office. In the following sketch we desire to ad- 
ance a new method of procedure that has proved itself very 
:ceptable by the rapidity and certainty of its operation. 
The history, as related by the owner, is to the effect that 
>r several months a cow had shown upon the left hind thigh, 
i the region of the coxo-femoral articulation, a large swell- 
ig, that he had permitted a butcher to incise, four weeks 
revious to sending for me. Despite the fact that a large 
aantity of offensive pus escaped, the enlargement did not 
minish, and the opening remained patent. The cow ate 
it little; gave little or no milk ; became thinner from day 
> day, and manifested great pain in the limb affected, being 
1 but unable to rise when down. Since the patient was one 
the most valuable of the owner’s animals, he insisted upon 
imediate action. 
We examined an emaciated, six-year-old cow, lying in the 
all; by urging, she slowly and with the emission of sundry 
rises, stood upon her feet. The region adjacent to the hip 
ticulation was much swollen, hard and painful upon pres- 
ire. About the width of a hand, anterior to and somewhat 
riow the ischial angle, there existed an aperture into which 
e could insert a finger several centimeters deep, and from 
hich there exuded minute quantities of a fetid pus, and
