Lake Mistassini—A letter to Science, from A. R. C. Selwyn, 
Director of the Geological Survey of Canada, states his belief that 
Lake Mistassini consists of several almost separate lakes, but 
that the entire body of water is not to be compared with that of 
Lake Superior. The exploration of the region was commenced 
in 1870-71, and last spring a party was despatched to continue 
the work. The sensational article in the Montreal Witness arose 
out of an interview of a reporter with Mr. F. H. Bignell, who ha 
just returned from taking winter supplies to the exploring party. 
The communication of Mr. Selwyn is accompanied by a tracing 
of Eugene Tache’s map of the province of Quebec, the only map 
upon which the results of the surveys of 1870-71 are correctly 
laid down. Geologically the lake lies in a basin of flat lying lime- 
stones, probably of Lower Cambrian age, resting on Laurentian 
and Huronian rocks. 
Dr. Carver. A Correction.—In your March number, p. 231, 
an error crops out in “ Carver the celebrated English traveler.” — 
According to the North American Cyclopedia, “he was an 
American traveler, born at Stillwater, Connecticut, in 1732, 
The notice proceeds with an incorrect statement, viz., “ He 
crossed the continent to the Pacific, and returned to Boston in 
1768, having traveled about 7000 miles 
Whereas, with a plan to go to the Pacific, he left Boston in 
June, 1766, went by the lakes, Green bay and Fox river portage 
to and up the Mississippi and the sources of St. Peter’s river, where - 
he wintered. He returned in the early summer of 1767 to Prairie 
du Chien, and in June, went, via the Mississippi and Chippewa 
rivers, &e., &c., to the north side of Lake Superior, coasted down 
to Sault St. Marie, then to Michillimackinac, where he spent the 
winter. “The next season he arrived in October, 1768, at 
Boston, after an absence of as ers and five months, and a 
journey of near 7000 miles,”
