EXTRACTS FROM EXCHANGES.

researches have shown in the vesicles staphylococcus pyogenes 
aureus and streptococcus pyogenes. It is easy to understand the 
action of these two microbes, which can live a long time on the 
ground, especially when it is damp, and hence enter the organ¬ 
ism through the abrasions of the skin of the digital ex¬ 
tremities. The treatment is simple and consists in dressings 
with sublimate. Prophylaxy consists in isolating the sick from 
the well animals, and in avoiding the low marshy lands where 
the microbes possess all their vitality.—( Archiv. Veterin.

Treatment of Capped Elbow by Collodion and Liga¬ 
ture \By Ouchmorov\. —When capped elbow contains liquid, 
or only begun to become organized, the author treats them as 
follows : The hairs are shaved all over the extent of the tumor; 
the skin is then washed with green soap and rubbed dry. All 
over the indurated part of the tumor, ordinary collodion is 
spread. If there is a wound iodoformed collodion (4 per cent.) 
is used. During the first week the application is made daily, 
then every two days. Generally after three weeks the tumor 
has disappeared. When the tumor is indurated or of cartilagi¬ 
nous consistency, collodion is powerless. The author recom¬ 
mends its removal as follows : An incision is made through 
the skin all around on the base of the growth ; in this a liga¬ 
ture firmly tight is applied ; the tumor is then projecting much • 
and its excision is easy with a bistoury or the thermocautery, 
which is better, being aseptic and arresting haemorrhage. Gen¬ 
erally the sequelae are very simple.—( Archiv. Veterin. Naouk

Fracture and Resection of a Rib in the Horse [By 
Blisnakov\. —A horse, one of a team, took fright, made a jump 
sideways and fell on the pole and one of the harness hooks tore 
his right flank, fracturing the last rib on the same side. The 
cutaneous wound measured about 20 centimetres, but the mus¬ 
cles under were torn about 50 centimetres long. The region 
of the last rib was somewhat swollen, the fracture of the rib 
was well detected ; the upper segment was concealed by the 
muscles; but the lower one was pushing upwards and out¬ 
wards. The skin of the flank was sutured with antiseptic 
thread and a bandage applied around the chest to keep the lower 
fragment of the rib in place. This proving unsuccessful, ex¬ 
cision of the lower portion of the rib was decided upon. The 
operation was done with the animal standing. The skin was 
divided on a level with the fracture, as well as the muscles be-
