a layer of sublimate cotton, and the skin sutured with disin¬ 
fected silk. After treatment consisted in frequent washing with 
a lysol solution. On the sixth day the stitches of the skin and 
the tampon were removed, and the wound healed smoothly 
without discharging. Weinhold found in a 17-year-old horse, on 
the left side, between the coxo-femoral and femoro-tibial articula¬ 
tion a soft swelling the size of a head, having on its summit a 
wound \y 2 cm. long. The exploring finger proved the presence 
of intestines, which prolapsed through a 15-17 cm. long rupture 
of the intestinal wall. The animal was placed on his back ; in 
the direction of the rupture a 20 cm. long incision was made, 
the intestines replaced and the ruptured wound closed with silk, 
and powdered with tannoform. The skin after the insertion of a 
drain tube was also sutured and powdered with tannoform. The 
horse received 1.0 gm. morphine hydrochl. subcutaneously. 
After treatment consisted in washing with lysol water. Drain- 
tube and sutures were removed after four days. The wound 
left a 10 cm. long narrow fistula, which discharged ; the horse 
was cast, the fistula opened, and a slough the size of a dollar 
was removed. Following this the wound healed very nicely.—

A New Colored Production of the So-called Cap¬ 
sules of the Anthrax Bacilli \lVolf Raebiger ].—In his 
procedure of producing the so-called capsules of anthrax bacilli, 
Raebiger avoids the fixation of the cover glass preparate by 
heat, and attains the same by treating it with formalin (40 
per cent, watery solution of formaldehyde). With this at the 
same time he connects the staining by dissolving anilin dye in 
formalin. To prepare the dye, formalin is poured, for instance, 
on gentian violet powder (15 gm. dye to 100 parts formalin), 
stirred, and left standing for several hours. The dye is good 
when all the powder is dissolved. This is then filtrated and 
preserved in a pipette bottle. The finely spread and thoroughly 
air-dried cover-glass preparate is then dotted with the formalin 
stain, which after 20 seconds, is rinsed off with water. In the 
examination, all the corpuscular bodies of the preparate will 
appear fuller and stronger, as a shrinking does not take place 
and the anthrax bacilli will show the true capsules. The latter 
are pale, and are contoured sharply on their periphery by a 
thick blue line, while the single right angular bacterial cells 
are separated by pale separating walls. The resulting pictures 
resemble those of the Johne’s procedure. However, the single 
bacilli appear stronger, and each will show with a certainty the
