Abstract

The Palaeozoic plant collection dealt with in this paper comprises specimens collected by Sir J. William Dawson who was principal of McGill University from 1855 to 1893. One of Canada's most distinguished geologists of the nineteenth, Principal Dawson pioneered paleobotanical investigations in North America. Much subsequent work, particularly in the coal fields of Eastern Canada, has been based on the discoveries of this famous scientist. Unfortunately, however, since the death of Sir William Dawson, no systematic restudy of this collection has been made.
