Collastina in Veterinary Surgery [By Dr. A. Bal- 
doni\. —Under this name the author refers to an emulsion of 
wax, gum arabic, glycerine, water and oxide of zinc, already 
used by an Austrian physician, and which has been more or less 
modified by Dr. Zenoni, of the Serotherapic Institute of Milan, 
who experimented with it as a new protective apparatus for 
heifers used in the preparation of Jenner vaccine. The author 
has tested its application in veterinary surgery and obtained 
with it excellent results. Collastina is a soft, whitish substance, 
with odor of wax and has great adhesive properties and can 
be readily spread over the surface of a wound of the skin, and 
adapting itself well to all irregularities. It can be rendered 
more aseptic by the addition of formaline, salicylic acid, salts 
of silver, etc. It is applied on the parts it is to cover after 
shaving off the hairs, and thorough disinfection. When sup¬ 
ported by a coat of wadding outside it forms an impermeable 
dressing. Used in large sutured wounds of the skin it has pre¬ 
vented the introduction of germs into the wound. It is very 
useful in regions where it is very difficult to apply a germ- 
tight dressing, as on the face, in the regions of the neck, of the 
shoulder, the croup, the withers, etc. In the dressing of foot 
operations, in wounds with loss of substance after periostotomy, 
in amputation of the tail, and specially for dogs its advantages 
are always very great. The author also recommends it as an ad¬ 
junct, a support in cases of fractures of the extremities of small 
animals. However, collastina is not free from one objection— 
similar to that of many forms of plasters ; it ordinarily be¬ 
comes loose after four or five days, but yet it has so many ad¬ 
vantages that it cannot fail to become more in use and to super¬ 
sede all other preparations used with the same object.—

Large Sanio-Purulent Collection in the Uterus of 
a Mare [By MM. C. Sanfelin and S. Vicariotto \.—For a 
month this mare has lost flesh and from the vulva throws a 
certain quantity of dense yellowish liquid when she is about 
micturating. She has been covered several times ; now she is 
thin, but shows no change in her pulse or temperature. In 
making rectal exploration the uterus is felt largely distended 
and by gentle pressure over it a whitish yellow discharge is 
made to escape by the vulva. The canula of a large syringe 
was introduced through the vulva and through it some 42 litres
