Accortling to Sand, Hoagland was the first to discover the spon- taneous activity of the lateral-line receptors and the former has PLATE A transverse section a little anterior to that shown in the previous Plate. The cere- bellum is larger. The acoustic tubercles are very prominent and have a tri- angular shape in section with a curved base. Where the apices approach each other the round celled tissue is replaced by scattered large cells. A small area of central acoustic tissue is still seen. —Cells of Purkinje. — Somatic-sensory lobes. shown that the lateral-line system is exceedingly sensitive to low- frequency \dbrations. " Direct mechanical stimulation of the lateral line, as well as vibrations propagated from a distance, are effective in exciting the reception, on account of the movements they cause to occur in the endolymph of the ; Let us consider what theoretical advantage to a deep-sea fish there would be in the in- creased development of the acoustic Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Evans, Harold Muir, 1866-.
