field are omitted. Thus the list of titles is to some extent selected, but the widest
possible range is covered with regard to the needs of the correspondent of the
Bureau.

It will be noted that all the publications have been priced. This is necessary
as there is clearly a limit to which the Bureaux can undertake the free distribution
of their literature. On the other hand, arrangements have been made to supply a
considerable number of copies free varying with the different publications.

The number of free copies of Animal Nutrition abstracts and reviews is strictly
limited. This journal is a joint effort on the part of the Executive Council of the
Imperial Agricultural Bureaux, the General Medical Research Council and the Reid
Library at the Rowett Institute, Aberdeen. The scientific reason for this joint
effort is apparent. On questions of nutrition it is impossible to draw a strict line
between the Research undertaken primarily for human benefit and that undertaken
primarily for the benefit of stock. Both those who are working on human problems
and on stock problems are interested in each others progress in research. As three
different bodies are financing this venture it was found necessary to limit the num-
ber of free copies issued.

Concurrently with the issue of these abstracting journals papers will be issued
by all the Bureaux on particular technical problems or containing bibliographies on
special research questions as hitherto.

CARBON TETRACHLORID AS A PARASITICIDE, BY HENRY L. HIRSCHER.

The following may be of interest to members of the profession who have work
with small animals and who have had no previous experience with carbon tetra-
chlorid as a parasiticide :

Animals infested with fleas or other kinds of vermin may be practically rid of
these infestations with one rubbing of a preparation having carbon tetrachlorid as a
base.

By saturating a piece of cotton or sponge with a little of this preparation and
rubbing it over the coat briskly, I can safely state that every parasite will be
destroyed, without the danger of spreading them all over the house. The hopping
off of fleas, especially when any parasiticide is used, is entirely eliminated.

The danger of poisoning, even in cats, is not apparent from my experience with
the use of this method. I really did fear it at the beginning, but now I use this
method indiscriminately in treating small animals. It may be used by any one,
even to rid the smallest puppy or kitten of fleas or other vermin. The action is
immediate. [Reprinted from the Journal of the American Veterinary Medical
Association, N. S. Vol. 32, 2.]
