Tfta unhappy termination of Mr. Sowerby's long illnoss, prevented the 

 appearance of the 06th number of Mineral Conchology, at the appointed 

 time. It is to be hoped that the materials left in the hands of his Sons 

 J. D. C. Sowerby, and C. E. Sovverby, will enable them to carry it on 

 regularly in future.
