Zoological Society. 139 be mentioned the Rev. Charles Clouson, Dr. PoUexfen, Miss Watt of Skaill, and Mrs. Traill of Woodwick. It is interesting to find, that the study of the Algse, which has been so highly honoured by numbering among its most successful cultivators a Mrs. Griffiths and a Miss Hill, still continues to be a favourite pursuit with our fair countrywomen. The Museum also contains about 100 species of shells, and nume-rous antiquarian and miscellaneous objects of interest. The number of ordinary members in January 1839 was 118. We trust that such an instance of what may be done by enlisting the poorer classes of society in the support of institutions of this character will not be without its \ise, but that the inhabitants of the towns of England will do for their poorer neighbours that which has been already done with such distinguished success by the clergy and other influential persons in the distant and stormy Orcades.
