Thus in wounds as well as on fetid animal matters disconnected naa 
the body this topic disinfects them at once, having no trace of odor 
yond a slight and not disagreeable smell of bitumen. 
He adds that this mode of disinfection occasions neither pain, irrita- 
= swelling or inflammation ; it also appears rather to favor than other- 
se, the progress of granulation and cicitrization ; there is therefore no 
inconvenience in applying it to various ulcers, sores "and wounds requiring 
to be disinfected.” 
Results equally favorable have been obtained at the veterinary estab- 
lishment at Alfo 
The Major General of the French army in Italy, anticipating these re- 
ported results gave orders for the use of this topic immediately for the 
relief of the wounded. The success of this treatment has been commu- 
nicated by Marshall Vaillant to the Academy. The report details the 
successful treatment by this means of gangrened sores upon twen ty 
wounded Austrians in the hospital at Milan. These cases the lane 
assert were of the worst possible character, and the success immediate 
and complete. 
hat is this remarkable topic? J¢ is a mixture of 100 parts of plas- 
ter of Paris with 3 parts of coal tar. The mixture is easily made in a 
morter. Its ieation is made by mixing the powder with olive oil. 
The application either of the powder or the pomade occasions no 
eve aced in direct contact with the surface. The treatment has the 
double advantage of disinfecting and also absorbing the pus—thus dis- 
pensing with the employment of lint—as the late experience in aly ot has 
abundantly proved. 
This simple mixture was originally prepared for the disinfection of ar- 
tificial manures. Its aut ok is Mr. Ed. Corne, veterinary sur 
tion and giving off an Sufbtiots odor has by this a et been instantly 
transformed into a odorless earthy mass.

chareoal powder, the Boghead coke, creosote and alkaline hypochlorites 
have for a long time been used as disinfectants. M. Chevreul next called 
attention to the fact that in the last century Dr. George Berkeley, Bishop

of this agent with er asm. It was esteemed by him as a spe 
More than twelve y mage Dr. Herpin of Metz propoed a disinfecting 
mixture of plaster sod eae Dumas reminded the Academy that one 
of its prizes was a few years since awarded to Mr. Sizet, who showed all 
the metallic salts which could be used with advantage in disinfection— 
who also added that the properties of these disinfectants were much ex- 
alted by the addition of a small proportion of coal tar. These experi-
