“ Dr. Steenstrup was born in 1813, and had thus reached the eighty-fifth year of his life. He published much on Natural History, but he will be principally remembered by his work on the subject of "Alternation of Generations." Our best course is to quote Geddes and Thomson on this point. "The progress of marine zoology and the study of parasitic worms gave naturalists like Sars, Dalyell, Loven, Von Siebold, and Leuckart early glimpses of many alternations in life-history, but Steenstrup was the first to generalise the results. ”
