The unhappy termination of Mr. Sowerby’s iong illness, prevented the 
appearance of the 66th 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. Sowerby, will enable them to carry it on 
regularly in future. 
No. 2, Mead Place , November, 1822.
