A SHORT HISTORY OF THE ENTOMOLOGICAL SOCIETY OF ONTARIO

Our society really owes its origin to an enthusiastic interest in entomology on the part of two young men who were beginning a study of insects shortly after the middle of the last century, and to the support and encouragement given them by a college professor who himself had a non-professional interest in entomology. These two young men were Charles James Stewart Bethune and William Saunders. The former was to become headmaster of Trinity College School and later head of the Department of Entomology and Zoology at the Ontario Agricultural College.

NEW ANOBIID BEETLE FROM CANADA

Specimens of an unknown Anobiid beetle infesting the woodwork of a house in Ontario were submitted to me by Prof. A. W. Baker, Ontario Agricultural College, Guelph, Ontario, for identification. It appears necessary to propose new names, both generic and specific, by which the species may be known.

A Study of Serum of Chickens Resistant to Rous Sarcoma

The purpose of this paper is to report some experiments carried out with serum of chickens which had been found to be resistant to Rous sarcoma. A study of these resistant birds has been reported in previous communications. A resistant bird is one in which a well developed tumor regresses; on further transplantation small nodules may develop, but these also regress, and the bird does not die of tumor. Pure-bred barred Plymouth Rock chickens obtained from the Ontario Agricultural College were used exclusively. The birds were from three to twelve months old. Tumor extract was prepared as follows: 3.0 gm. of tumor tissue were ground with sand and 3 c.c. of concentrated saline; this was allowed to stand fifteen minutes; 100 c.c. of distilled water were then added and the mixture was centrifuged. In some cases this extract was filtered through layers of sand and paper pulp, as described by Gye. This type of extract was called sand filtrate. Only one injection was given to each bird at one time. As a rule, three birds were used to test each serum mixture. All tumor extracts or sand filtrates were tested on three birds. Sodium citrate was used when drawing blood to prevent clotting. In some instances heparin was also used.
