180 THE ESSEX NATURALIST. It was also a question whether it would be desirable to introduce animals which had become extinct in this country, such as the elk, reindeer, wild pig and the beaver. It might not be possible to get the right food for them in Scotland and that would make them difficult to acclimatise. There was one animal, however, namely, the Irish stoat, which only occurs in Ireland, which should be introduced into a national park if one were provided in Scotland.

He re- ferred to the paper by our President, read at the previous Delegates' Conference, concerning the formation of an Association for the study of systematics in relation to general biology, and then gave some account of what had been done since that date. A questionnaire had been submitted to certain specialists as to the state of our knowledge of various animal groups. Answers were now being received, and it was clear that in nearly all groups there was lack of information as regards distribution. Much further work was evidently required, and it was proposed to adopt
