tity of bisulphide used; what is not evaporated will serve for a uew 
charge. 
The disagreeable odor of bisulphide of carbon is not persistent; it is 
not even necessary to spread open the mounting-sheets; it is only neces- 
sary to expose them, unopened, to the air. I would call attention, how- 
ever, to one very necessary precaution, if accidents are to be avoided. 
The vapor of bisulphide is very inflammable, and the chest must, there- 
fore, be set in a safe place and not opened near a fire or any flame what- 
ever. It would be risky, for example, to unpack the chest in the even- 
ing while holding a lamp in the hand. 
As the odor of bisulphide is very disagreeable and may cause dis- 
comfort to some persons, all these operations should be performed in 
an attic or in an apartment of which the windows may be left open as 
long as necessary. 
PRESERVATION OF FURS AND WOOLENS. 
The same process maybe used in the preservation of .clothing in 
clothing establishments, civil or military, where Tinea and Attagenus 
sometimes cause such ravages. Special arrangements maybe adopted 
in establishing fumigating chests or rooms to avoid the settling due 
to weight and to facilitate the penetration of the gas. 
This method makes it certain that we shall not " shut the wolf up in 
the sheepfold." Articles fumigated are entirely rid of eggs, larvae, and 
living insects. They may be shaken out in the open air for greater 
security and then replaced on the shelves, with the assurance that they 
will not be found gnawed when next visited. 
PRESERVATION OF THE STUFFING- OF FURNITURE AND SADDLES. 
Tinea and Attagenus have a marked predilection for horsehair, so 
that these insects are sometimes found flourishing in the stuffing of 
our furniture, even that which is in daily use. This process has the 
advantage of permitting us to destroy them without having recourse 
to the upholsterer; we need but to construct a fumigating chest large 
enough to contain a couple of armchairs or more. In the same way we 
may treat mattresses, eiderdown quilts, or anything which is supposed 
to contain eggs or larvae. 
I have experimented with a saddle much damaged by moths, and 
after fumigating it five days noticed no appearance of insects; the 
saddle was completely penetrated by the vapor and all the moths per- 
ished. I kept it two years under observation in order to be assured 
of the efficacy of the process. 
DISINFECTION IN EPIDEMICS. 
I am persuaded that clothing subjected to this process would be dis^ 
infected quite as well as by the processes usually employed in certain 
epidemics, such as typhus, cholera, smallpox, etc. It seems to me that
