360 NATURAL SCIENCE. May, 1895. 



and asked some definite and pertinent questions. We waited so long in vain for 

 answers to our questions that we felt none were contemplated, presumably because 

 the international bureau was even less than a castle-in-the-air. Accordingly, we 

 began to make arrangements for enlarging our list of periodicals, and were about to 

 issue a second circular guaranteeing at least ninety-five per cent, of all zoological 

 titles at a definite and very low price, when we received a reply to our questions 

 from Dr. Field (who had been as prompt as circumstances would permit). 



Dr. Field's letter indicated an actual move towards a realisation of the inter- 

 national bureau ; and in the light of the facts disclosed we dropped all our plans, 

 and expressed to Dr. Field our best wishes. 



We present no claims for glory, priority, or anything of that sort in this matter. 

 Our only desire is to see this very important work begun. Once begun it will be 

 continued. At present, however, there is altogether too much importance attached 

 to the active co-operation of certain excellent but painfully " slow " societies. 



We are still printing our own card catalogue, and are furnishing it to a few 

 friends, but are no longer offering it at any price. We urge everyone to encourage 

 the movement aiming at the establishment of a central bureau at once.

The Leeward Islands. 



In our March number we praised the colonists of these islands for their practical 

 appreciation of science, especially as applied to agriculture. We regret to hear as 

 follows from Mr. C. A. Barber : — 



" By vote of the Local Legislature the office of Superintendent of Agriculture 

 has been abolished, and the Department of Agriculture of the Leeward Islands, as 

 such, no longer exists. The Library which I have been engaged in collecting during 

 the last few years, and to which any journals and reports received have been added, 

 I have handed over to Mr. Watts, the Government Analyst, Antigua, as Secretary of 

 the Antigua Agricultural Society." Mr. Barber's address for the present is 16
