Abstract
YET another of the links that have bound the geologists of the present time in association with the early leaders of their science has been severed by the removal of the kindly and venerable form of Dr. Bigsby. Upwards of sixty years ago he began his geological career in North America, devoting himself mainly to the investigation of the structure of the older Palæozoic rocks of Canada and of the adjoining tracts of the States. As secretary to the Boundary Commission under the Treaty of Ghent he had opportunities of investigating the region from Quebec to Lake Superior, and published numerous descriptions, of which the exactness has been amply verified by the subsequent researches of the Geological Survey of Canada. It is chiefly as an admirable pioneer in Canadian geology that his name will be inscribed in the records of scientific progress. But he has other claims to grateful remembrance. Since he returned to spend his later years in this country he has devoted himself with the most untiring patience to the compilation of his “Thesaurus Siluricus” and “Thesaurus Deronicus”—works in which the geological and geographical range of the organisms of the earlier half of Palæozoic time is clearly shown in a series of valuable tables.
