If phosphoric acid be agreed upon as the term for common use, 
then concentrated superphosphate will be represented as contain- 
ing 45 or 46 per cent, of phosphoric acid, mostly water soluble, and 
ordinary superphosphate will be represented as containing 16A- to 
17^ per cent, or more, phosphoric acid, mostly water soluble. If 
phosphate of lime be agreed upon as the term for common use, the 
concentrated superphosphate must be stated as containing from 98 
to IOO per cent, phosphate, mostly water soluble, and the ordinary 
as containing 36 to 38 percent, phosphate, mostly water soluble. 
I feel sure that I can successfully appeal to all respectable 
manure manufacturers and merchants, who recognise that the 
spread of precise knowledge as to the real nature of manures is in 
the interests of all concerned, to adopt that system which has heen 
agreed to by a consensus of opinion amongst the leading chemist 
of the day. All buyers of superphosphate should insist upon being- 
informed as to how much water soluble phosphoric acid the manure 
is guaranteed to contain. ’ '

Gutta Percha in Ceylon. 
It is reported that Mr. Hcrbeit Wright of the Ceylon Botanic 
Gardens Staff is in charge of an expedition to the Hilly districts of 
the S. W. of Ceylon for the purpose of investigating the trees there 
which produce gutta percha. Dr. Trimen describes seven species of 
Palaquim in the Flora of Ceylon but adds “Our species are ap- 
parently ill defined, but I have had little opportunity of examining 
them in a living state. All are endemic, and inhabit the wet forests 
of the low moist region, They yield a milky juice (Gutta Percha) 
but none is collected from Ceylon species” — Mr, Wright, however, 
in writingto a friendi n Colombo. Says “ Hinidoonkanda is just the 
place I anticipated. The soil is very poor, there is plenty of water 
and an altitude of 2,200 feet. Under such conditions you will not 
be surprised to learn that I found over 70 trees of the particular 
species required, and some of which attain considerable dimensions 
There is plenty of gutta percha in these trees and I could go on
