230 THE ENTOMOLOGIST. 



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. I have 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.
