PRESERVATION OF BOTANICAL AND OTHER SCIENTIFIC 
COLLECTIONS.—Those who possess a herbarium of any size, or 
a collection of entomological specimens, are frequently greatly 
troubled by the presence of mites and similar small pests. These 
may be got rid of in a most effectual manner by the use of Bi- 
sulphide of Carbon (Carbon disulphide). In each compartment 
of the herbarium a small fragment of sponge is placed, and a few 
drops of the liquid poured on it. The whole must be closed up 
as quickly as possible, in arder to permit the poisonous vapour 
to act most effectually. Every form of life, animal or vegetable, 
is quickly destroyed, and, in the case of insects, even the eggs: 
are all killed. The objections to the use of this substance are 
that its vapouris both deleterious and of a most offensive odour, 
so that it cannot be used in aliving-room. If, however, the room 
containing the specimens can be shut up for two or three days, 
this process will be found to be the most perfect yet devised. 
NEW SCIENTIFIC JOURNAL.—“ Science” is the name of a 
new illustrated periodical which is being published by “the 
Science Company,” of Cambridge, Massachusetts, U. S. A., and 
the first number of which was to be brought out on January: of 
this year. The president of this company is Dr. Alex. Graham 
Bell, and, to judge from the prospectus, it is the intention of the - 
promoters to make the journal a first-class publication. 
THE LATE PROFESSOR BALFOUR.—From a circular now 
before us we learn that a public meeting was held in Cambridge 
on 21st October, to consider the most appropriate form of me- 
morial to the late Professor Francis Maitland Balfour. The fol- 
lowing resolutions, among others, were unanimously agreed to :— 
“ That the memorial take the form of a fund, to be called the
