Rehbock* INTRODUCTION AT THE NORWICH MEETING of the British Association for the Ad- vancement of Science in August 1868, Thomas Henry Huxley announced the results of his microscopical examination of some specimens of North Atlantic bottom sediment. Among the constituents of these seemingly unexciting speci- mens Huxley had found some curious "granule-heaps," surrounded by extensive masses of viscous matter, which he described variously as "lumps of a transparent, gelatinous substance" and a "colourless, and structureless matrix."' Tests of the substance convinced Huxley that he was dealing with a new type of organism in the form of virtually undifferentiated protoplasm. He gave the organism the generic name Bathybius, after its oceanic habitat, and called the species B. haeckelii, after his friend and fellow champion of Darwinism, Ernst Haeckel. Bathybius haeckelii was to live a brief but eventful life of some seven years. In 1875 the scientists aboard H.M.S. Challenger, then nearing the end of their epochal voyage for the establishment of the new science of oceanography, discovered that Bathybiuswas nothing more than an inorganic precipitate. Despite his obvious embarrassment, Huxley readily admitted his error. Haeckel, however, who had applauded Huxley's original discovery, would not give up so easily. For him Bathybiuswas both an important member of his new class of unicellular organisms, the Monera, and a keystone in his mechanistic philosophy of life.

Previous narrations of the Bathybiusstory have been characterized by a brevity and jocularity which obscures the seriousness of the controversy and the zeal of the debators. To be sure, there is a comical tone to the affair, deriving from the comments of the participants, especially Huxley, and from the subject matter itself (reminiscent of stories of sea serpents and other abyssal curiosities). But there is also a grave aspect, manifested in the immense efforts expended on laboratory investigations, ocean dredgings, and publications in scientific journals, all in behalf of a nonexistent organism. Loren Eiseley has called Bathybius "one of the most peculiar and fantastic errors ever committed in the name of science."3 At first sight it may seem strange that some of the most distinguished biologists of the nineteenth century should have been allied with such a "fantastic" error. Professor Eiseley claims it to be "the product of an over-confident materialism, a vainglorious assumption that the secrets of life were about to be revealed."4 This analysis is incomplete, however, for it lays the blame on a philosophical predisposition while ignoring the unique sequences of events in several scientific disciplines whose timely convergence made Bathybius"'discovery" possible. Bathybiuswas simultaneously a candidate for the lowliest form of protozoologi- cal life, the elemental unit of cytology, the evolutionary precursor of all higher organisms, the first organic form in the fossil record, a major constituent of modern marine sediments, and a source of food for higher life forms in the otherwise nutrient-poor deep oceans. Among biological entities Bathybius was probably unsurpassed in the variety of scientific specialties from which confirmation seemed forthcoming. Its eventual refutation came from outside this group of specialties, from the knowledge and techniques of chemical analysis. The present study attempts to trace out the full course of Bathybius' birth, development, and demise, emphasizing the complex milieu of scientific theories which allowed the "organism" its brief existence. PRENATAL CONDITIONS OF BATHYBIUS The idea that life on earth arose originally in the sea is one of the oldest speculations of natural history. Variations on this theme appear in the philosophy of the Milesian Anaximander5 and more recently in the speculative biology of the NaturphilosopheLorenz Oken (1779-1851). Oken believed that life began as a primitive mucous substance which evolved from inorganic constituents existing in shallow marine waters. He equated the individual vesicles of this mucus with the smallest organisms known at the time, the infusoria.

REHBOCK organisms, according to Oken, were made up of, were "metamorphoses" of, these infusoria.6 Oken's writings, though mystical in tone and erroneous in many details, were strikingly anticipatory of later developments in biology, including the cell theory of Schleiden and Schwann and the protoplasm theory which followed it.7 The early history of these theories has been well described elsewhere.8 For present purposes it should be recalled that by mid-century the initial conception of the cell, a unit characterized by a definite boundary or cell wall, was being questioned and new light was being cast on the nature of the cell's contents. Franz Unger's demonstration of the identity of the cell substances of plants ("sarcode") and animals ("protoplasm") in 1850 initiated an era of intensive protoplasmic research. The decade of the 1860s witnessed the most intensive investigations and speculations about protoplasm. Two events of particular interest marked the beginning and the end of this decade. In 1861 the German microscopist Max Schultze (1821-1874) published his essay "Uber Muskelk6rperchen und dass was man eine Zelle zu nennen habe,"9 in which he described his examination of membraneless protoplasm in marine invertebrates. Schultze's work convinced most scientists that the truly essential portion of the cell was not its outer membrane but its contents, the protoplasm and nucleus.'0 And in 1868 T. H. Huxley, by then a protoplasm devotee himself, placed the protoplasmic theory before the public in his famous lecture "On the Physical Basis of Life." "' Huxley's lecture generated much interest because, along with his strong support of the protoplasmic theory and its physicochemical basis, he brought serious criticisms against both vitalists and positivists. 12 In his espousal of protoplasm Huxley failed to mention, however, that in an earlier essay he 6Lorenz Oken, The Elenents of Physiophilosophy,trans.
