INTRODUCTION.

The plates and sheets thus dispersed were however with difficulty 
and at considerable expence brought together by the spirited conduct 
of the present publisher, Mr. H. G. Bohn, who, anxious that the work 
should if possible be completed, again applied to Mr. Gray, but much 
against my wishes. That gentleman however repeated his offer of 
assistance, but as before it served only to delay the work another year. 
At length Mr. G. B. Sowerby was engaged to complete the Conchology, 
and to revise the unprinted portion of Mr. Gray’s MS., and thus after 
an unprecedented and vexatious delay, and with a considerable additional 
expense, I am now only able to submit the work to the public.
