Note 14 — Chapter I · VOYAGE FROM NEW YORK TO RIO DE JANEIRO.
Reading edition
As these investigations have been published with so much detail (Steenstrup, Alternate Generation, Sars’s Fauna Norwegica; L. Agassiz, Contr. to Nat. Hist. of U. S.), it has not been thought necessary to reproduce this part of the lecture here. Any one who cares to read a less technical account of these investigations than those originally published, will find it in “Methods of Study,” by L. Agassiz.
