The only Scientific American cover featuring plankton collection

Cover of Scientific American issue containing a never cited article: Kofoid, C.A. 1912. A new apparatus for marine exploration. Recently invented deep-sea nets. Scientific. American, 106:174. The article begins with the surprisingly long and inaccurate sentence "The clear water of the open sea, even to considerable depths, has been found by the explorations of the "Challenger" expedition of the British government, by the German Deep Sea Expedition of the "Valdivia", and especially by the explorations of the United States steamers, "Blake" and "Albatross," conducted during the past thirty years in the Atlantic and Pacific oceans under the direction of the late Alexander Agassiz, to be more or less densely populated by pelagic animals and microscopic plants or their remains, of remarkable interest and beauty, and one of the questions raised by these explorations has been as to the depths in the sea to which these organisms descend, or at least are abundant.
