Owing to the New Regulations. It has becomes necessary for all who with to graduate in Medicine at the Calcutta university to obtain knowledge of the structure of animals by dissection. The anatomy of vertebrate types is described in many good books, but the common invertebrate animals of Bengal, which are peculiar to the country, have not been described hitherto in any text-book. It is necessary that the types for dissection should be of common animals, which may be obtained in large quantities. In England even Protozoa can be conveniently obtained by purchase. This is not the case in India; but the source of the material for our classes must be as certain as in other countries. The types selected are not in all cases those required by the University syllabus, Eunice, Bipalium, and certain Echinoderms, cannot be obtained in sufficient quantities for classes which may number as many as one hundred and fifty students. Because it was urgently required, the book has written somewhat hurriedly, and is therefore likely to contain errors.
