Fiorentini and Luraski have experimented on guinea-pigs in¬ 
oculated with cultures of human tuberculosis. In a first series 
six animals were used, three inoculated, three witnesses. Sub¬ 
mitted to the Roentgen rays during an exposure of forty min¬ 
utes every day, it was shown that, when applied for eight 
consecutive days, it had arrested the development of the tuber¬ 
culous process. In a second, the authors used stronger cultures. 
Two pigs received one cubic centimetre, and eight half of a 
centimetre. One of each division was submitted to the rays 5 
the others were kept as witnesses. All of those last died with 
tuberculosis in a length of time varying between fifteen and 
thirty days. Of the other two, the one which received one cubic 
centimetre of culture was submitted to the rays every day for 
twenty-three days. After fifty-three days, much emaciated, he 
was destroyed and presented lesions of chronic peritoneal tuber¬ 
culosis. The other, which had received half a cubic centimetre 
of culture, was submitted to the rays ten days after the inocula¬ 
tion, when he already presented a large tubercle at the point of 
inoculation, and signs of failing and loss of flesh.^ With the 
rays, the ventral nodosity disappeared, the animal increased in 
weight and is now in good condition. He was exposed for 
twenty-five days, forty minutes at each exposure. The authors, 
in conclusion, say that they cannot explain the beneficial influ¬ 
ence of the X rays upon the tuberculous organism, but are satisfied 
in confirming by their experiments the results already obtained 
in France in the attempts made on their application to the treat¬ 
ment of the disease in man .—{^Giornale della Real. Soc. Veter 1 ) 
BELGIAN REVIEW. 
Pelvic Abscess in a Horse. —This lesion is not uncommon, 
sometimes very troublesome, in some instances fatal. The favor¬ 
able end met by the patient of Mr. Verlinde, which is published 
in the fo2ivnal de Ih'iixelles^ is very interesting. A horse was 
stopped from working for lameness of the right hind leg. The 
leg was swollen, hot and painful in its upper regions. The anus 
was prominent, deviated to the left ; the animal moved with 
difflcnlty ; the right hind leg had very limited motion ; the tail 
was carried to the left. Defecation was difficult and painful, 
faeces small and maculated with pus. By rectal examination the 
size and location of the abscess were well made out. Rectal injec¬ 
tions, emptying of the abscess by enlarging the fistulous tract it 
had in the rectum with the finger and with the lancet, washing
