“I have lately had the opportunity of examining a series of fossils from high arctic latitudes, brought home by Captain M'Lintock, R.N. The series in one sense is extensive, as there are Silurian and oolitic shells, and also other fossils of the tertiary times. Among these last there are some things which, I am sure, will be of interest to you. Among the specimens are some recent and living shells from Baring's Island, of which I will send you a list when I determine the species.
