sulphate, zinc sulphate, all developed aborescent forms, 
but differing in shape. Other compounds, such as ferric 
chloride, assume shapes which simulate fungoid growths. 
The growths are rigid and consist probably of silicate of 
the metal, but have not yet been analysed.

Sir,—Referring to my communication of Ist February, 1906, with 
respect to the request of the Natural History Branch of the British 
Museum, for specimens of the various species of blood-sucking insects, I 
have the honour, by direction, to inform you that from a later communi- 
cation from the Colonial Office, it appears that you are desired to be good 
enough to forward further specimens of blood-sucking insects collected 
in this State to the Quick Professor of Biology, New Museums, Cambridge, 
similar to those already forwarded, and, as far as possible, that future 
contributions should be divided between and simultaneously despatched 
to, the Director, Natural History Museum, and the Professor of Biology 
already mentioned. 
2. [am directed by the Chief Medical Officer of the Government to 
add that the opportunityis taken of again commending to the attention 
of the members of your Society the importance of forwarding the collec- 
tive enquiry in progress, in view of the part played by various insects in 
the transmission of human and animal diseases, and of pointing out that 
by the two institutions the subject will be regarded from rather different 
points of view. I have the honour to be, Sir, your obedient servant, 
JAMES J. POTTER, for Secretary. 
The Secretary to the Royal Society, 
Royal Society’s House, Elizabeth-street, City.
