Toronto Naturat History Society, Nov. 7.—Henry Mont- 
gomery, the president, gave a lengthy address upon “ The Rela- 
tions of the Blastoidea,” copiously illustrated by specimens of 
existing and extinct sea-urchins of various genera, star-fishes, 
brittle-stars, crinoids, trepangs and Blastoidea of the genera Pen- 
tremites and Nucleocrinus. Of the last-named genus the lecturer 
exhibited the specimen recently described by him in his paper on 
“A Blastoid found in the Devonian rocks of Ontario.” Mr. 
William Brodie then showed specimens of fiber from the upper 
sheaths of the “broom” grass, Adropogon scoparius, well adapted 
for the manufacture of cordage and paper. In his address Mr. 
Brodie claimed that this grass can be utilized to reclaim dry, sandy, 
waste land. The samples shown were remarkably tenacious.

THE SIXTEENTH VoLUME oF THE AMERICAN NATURALIST.— 
Although no promises of enlargement were made to our sub-
