contain it, this neutralizing property, they have been ignorant of 
the manner in which it acts on the corrosive sublimate, and the 
nature of the compound which results. In order to fill up this 
chasm, M. Lassaigne has, during this year, instituted a course 
of new experiments on the compound, from which he draws the 
following conclusions : 1st, That the albumen, contrary to what 
some authors have advanced, combines instantly with the cor- 
rosive sublimate without decomposing it ; 2d, That there results 
from this combination a definite compound, containing ten atoms 
of albumen and one of corrosive sublimate (deuto-chloride of 
mercury); 3d, That this substance, among other things, has the 
property of being soluble in cold watery mixtures of alkaline 
compounds of chlorine , bromine, and iodine ; 4th, That this 
solubility, hitherto unknown in salt water — a solution of the 
chloride of sodium — should awaken the attention of medical 
men and veterinary surgeons, and tends to explain how, under 
certain circumstances, the sublimate, in combination with both 
albumen and salt, may retain a portion of its active properties. 
The Professor has made the same observation with regard to 
the fibrine of muscles, which combines with the sublimate 
without decomposing it, and is thus preserved from decomposi- 
tion at the ordinary temperature for a considerable length of 
time. 
A concretion, found by Mr. Renault in the right ventricle of 
the brain of an old horse, was subjected to analysis. It formed a 
tenth part of the weight of the whole brain. It consisted of 
58.076 parts of cerebral cholesterine, 39.5070 of membranous 
albuminous matter, and 2.5070 parts of phosphate of lime. 
M. Lassaigne is also occupied with M. Delafond in a chemical 
analysis of the different concrete substances produced in farcy 
and glanders. These experiments are made with a view of 
putting to the test the new theories with regard to the cause and 
products of these maladies. 
Two young veterinarians, who were educated at this school, 
having witnessed the good effects of certain remedies employed by 
some empirics in that country in the cure of sand-crack in the 
horse and foot-rot in the sheep, have sent us a portion of the me- 
dicaments. There are two preparations ; the one is an ointment
