remain there in quarantine until all chance of communicating 
the disease has been baked out. In my cabinets, constructed 
by Benjamin Standish on an antediluvian plan of my own, 
there is a cavity all the way round, technically known as a 
camphor-cell, and camphor it formerly contained; but when 
it became manifest that camphor was neither ornamental nor 
useful,—in fact, that it was highly deleterious to Lepidoptera, 
-—camphor was ejected by a summary process, and the cells 
stuffed full of calico-rags, on which benzole is occasionally 
poured. Ihave no objection to cajeput, and the scent is 
more pleasant than that of benzole; but the effect of cajeput 
on a living Atropos pulsatorius is less rapid. Between the 
camphor era and the mercury era Mr. Doubleday always 
used oil of cajeput, but now he invariably touches the under- 
side of an insect with a weak solution of bichloride of mercury 
in alcohol: this process effectually prevents grease, mites or 
mould. In using this solution some care is requisite that it 
be not made too strong, for this is possible, since the insect 
may be disfigured by a slight change of colour or by a 
crystallized coating of the bichloride. In order to test the 
strength of the solution a sheet of black or dark paper should 
be at hand, and a portion of the solution laid on it with 
a camel’s-hair brush; if there appears the least coating of 
white on the paper add more alcohol, and continue adding 
and testing the solution until it will dry and leave no mark 
whatever: it is then fit for use. I shall be very pleased to 
receive and to publish the opinions and experience of others.
