Huge volume containing an important collection of articles and papers on fish and especially eels, by the Danish biologist Ernst Johannes Schmidt (1877-1933), probably all his papers published in this period. Schmidt is best known for his findings on the migration patterns and breeding places of the eel, which he researched during various Danish expeditions in the North Atlantic Ocean and the Mediterranean Sea. He also, accidently, caught the first leptocephalus larva outside the Mediterranean Sea, which are also discussed in many of the papers. The book opens with a general title-page Havundersøgelser (Ocean studies), followed by a portrait, a letter and all the articles. Most of them are written in English, although a few are in Danish, German or French. Discussed in the articles are eels and their larvae, cod, halibut, sun-fishes and other fish, and one deals with various turtle species in the Danish West Indies. Many of the articles include illustrations in text, folding plates, maps and/or tables, showing migration routes, a fish's growth stages etc. Full list of contents available on request.
Browned throughout, some articles have frayed or slightly torn margins or dog ears. Binding slightly worn along the spine. Overall in good condition. Dean II, pp. 405-407, cf. H. Ueda, Physiology and ecology of fish migration, p. 82.
