Dear Sir, 
Owing to the Editor of "Ornis" be- 
ing abroad our letters to him did not receive at- 
tention until this week, we regret this delay 
which was unavoidable. He now informs us that he 
has had the numbers published forwarded and the 
continuation will be sent to you as issued. We 
enclose the invoice herewith. 
By last mail we sent you a new part 
of the Proceedines of the Zoological Society and 
enclosed with it a prospectus of a new work on the 
birds of Kent, which we shall be pleased to sup- 
Pay, if desired. 
Yours respectfully,
