pra.ctio able. 
I understand that the insects cannot be count¬ 
ed until the spsoiiaens have been relaxed. It will 
be inpossible for you, therefore, to indicate on the 
memorandxun to the Registrar the number of specimens 
in the various consignments. You will probably be 
only able to give the total of packages, but in that 
case any serial numbers or letters which they bear 
should be placed on the memorandum. 
Very sincerely, 
Head Curator of Biology.
