The Johns Hopkins lJ7niversity, School of Medicine SEVEN FIGURES Marshall and &&in ( '28), in their work on the kidney of the goosefish, Lophius piscatorius, reported seventy-eight glomerular structures in an entire adult kidney. I n the same kidney there was an estimated minimum of 150,000 renal tubules, or an average of 2000 tubules to each glomerulus. They felt that on this basis alone the kidney could be considered from the functional standpoint as an aglomerular organ. On the other hand, there were certain peculiarities of the glomeruli which led these observers to consider them non-functional and to call them pseudoglomeruli. I n examining thin serial sections, some of the glomeruli were found to have no connection with a renal tubule. In other 2 0 p sections the presence of a connection between the glomeruli and tubules was debatable in two instances, and in one instance they felt the presence of a tubular connection to be definitely established. Furthermore, Bowman's capsule was almost invariably distended with coagulable fluid, and in numerous instances showed curious outpouchings. Finally, the glomeruli were situated only at o r near the periphery of the kidney, and were always surrounded by a very vascular tissue, called sinusoidal tissue. The glomerular tufts and *Part of the adult material used for this investigation was collected at the Mount Desert Island Biological Laboratory, Salisbury Cove, Maine, during the summer of 1927. The rest of the adult material was collected at the Marine Biological Laboratory, Woods Hole, Massachusetts, during the summer of 1928. The maceration study was carried out at the Marine Biological Laboratory.
