PROPOSED IMPERIAL CONFERENCE OF ENTOMOLOGISTS. 
It has been suggested by the Imperial Bureau of Entomology that a 
conference of entomologists of the Empire, which was deferred during 
the war, should be held in London at an early date. The objects of the 
gathering are to discuss problems of Imperial importance in the pre- 
vention of the spread of insect-borne diseases, and to afford an oppor- 
tunity of placing the entomologists in closer touch with the Bureau of 
Entomology and of settling lines on which the Bureau may render 
further assistance to the different parts of the Empire. An invitation 
to the Commonwealth Government to participate in the scheme was 
recently sent by Lord Milner, Secretary for External Affairs, and the 
matter has been referred to the Institute of Science and Industry for 
consideration. The Director, Professor Watt, Mr. G. Valder, Dr. S.S. 
Cameron, and Mr, A. E. V. Richardson haye been appointed a special 
committee to inquire into the proposal and to prepare a recommendation 
for submission to the Government. 
_ Manufacturers and primary producers are invited to state their 
difficulties to the Institute’s Bureau of Information, which will assist 
them where possible. 
___ Two more Bulletins, one on Cattle Tick and another on Posidonia 
Fibre, together with a pamphlet on Engineering Standardization, have 
been issued during the month from the publishing department of the 
Institute. : 
It has been decided that a nominal charge of 6d. for each Bulletin 
and Pamphlet issued by the Institute, and 3d. for each circular shall in 
future be charged, so as to restrict the demand to those genuinely in- 
terested. 
The Department of Scientific and Industrial Research has forwarded 
to the Institute a number of copies of A Study on the Performance 
of Night Glasses, by L. C. Martin, D.I.C. These can be obtained on 
application to the Secretary. 
An informative pamphlet, by Gerald Lightfoot, M.A., on “ Engineer- 
ing Standardisation,” ‘has been published by the Institute. . 
The technical and scientific library of the Institute is each day being 
made more complete, and is available for the inquiring public.
