COWDRY Tie Roekefeller Institute for Medieal Researeh CYTOLOGICAL CONSTITUENTS--MITOCHONDRIA, GOLGI APPARATUS, AND CHROMIDIAL SUBSTANCE EDMUND V. COWDRY I. MITOCHONDRIA1 1. Discovery: Although it is customary to trace back our knowledge of mitochondria to the brilliant researches of Altmann at Leipzig between 1880 and 1890, they were certainly seen and imperfectly described by other workers before him, notably by Flemming. Some of the bodies called "Interstitial Korner" by Koelliker, "Neurosomen" by Held, and "Cytomicrosomes" by Strasburger were clearly of mitochondrial nature. Other pioneers in cytology must also have observed them (von Brunn, L. and R. Zoja, and J. Arnold). Their relation to the chromidial substance and to the Golgi apparatus (first detected at about the same time) occupied much of the attention of the earlier workers in this specialized field. The cell seemed already to them so complicated that they were naturally loath to accept the occurrence of two additional and morphologically independent cytoplasmic constituents without convincing proof. The interesting discussion which arose is well summarized by Duesberg (1912). Thus, it has only been during the past thirty-five or forty years, slowly, with gradual improvements in technique, that the distinctive characteristics of mitochondria have come to light. We are now entering upon a period of experimentation. 2. Definition: Mitochondria are composed of material exhibiting the following general properties: a) It is of rather low refractive index but with care may be seen to occur in living unstained cells in the form of granules, rods, and filaments, and occasionally of networks, which va...
