world, and is published in English, French and German. 
It contains also a large number of receipts for vulcanizing 
for various purposes in which we notice that Pontianac, 
that is to say Jelutong plays quite an important part. 
Many would be surprised to see how little of the rubber 
goes into some of the cheaper vulcanized articles of every 
day use. 
1 he booklet is more likely to be of use to the manufac- 
turer and dealer in rubber articles than to the planter, but 
to them it will doubtless supply a want in an efficient 
manner. It is procurable from the office of .the journal 
above-mentioned, 49 Rue des Vinaigriers, Paris.

JOURNAL OF THE COOPER RESEARCH 
LABORATORY. 
Me have received a copy of the first Journal of this 
Laboratory which is situated at Rerkhampstead in England. 
It is a well bound and illustrated book of seventy two pages, 
dealing with the work of the staff, of especial value are the 
experiments with Insecticides and Fungicides, use of lime 
in Agriculture and Copper as a Fungicide. 
The staff do not only carry on researches of this kind 
valuable as they are, but undertake inspections of orchards, 
crops and stock suffering from disease, hold consultations 
with Colonial Departments of Agriculture, Country Coun- 
cils and such bodies and maintain a Museum of pests and 
beneficial insects showing their Jife-liistories and the 
damage they do. The laboratory was founded by Sir 
Richard Cooper in 1902, who is principal of the Laboratory, 
and maintains a staff of twelve persons. The Director Mr. 
Walter E. Collinge edits the report. Such experimental* 
laboratories are absolutely invaluable, and it is a cause of 
surprise to many that we have so very few in our vast 
Empire.
