Wagner* be- lieves that the normal relation between the nerve-tubes and corpuscles is, that each pri- mitive nerve-fibre coming from the centre, retains its appearance of double contour up to the ganglion-cell, where its contents are interrupted by the finely granular matter of the latter; at the peripherical extremity of the cell, the nerve-fibre commences in a quite similar manner. Thus then, according to Wagner, the oily contents of the nerve-tube cease on reaching the ganglionic corpuscle. Bidderf, on the other hand, regards the clear white space between the cell-wall and the granular contents as a thin sheet of nervous matter, which serves as a connecting medium between the contents of the nerve-tube on either side of the ganglionic corpuscle. As regards the sympathetic ganglia in this animal, they appear in some parts to be almost entirely composed of a fibrous structure and of a quantity of granular matter resembling, as Wagner and Kobin observe, the gray granular matter of the nervous centres, and containing a number of bodies of a brownish- yellow granular appearance, which do not dis- * Handwbrterbuch der Physiologic, bandiii. p 301. et set}. f 7ur Leben von dem VcrhUltnisz der Ganglien, korper zu den Nervenfasern, Leipzig, as quoted in Canslatt's Jahresbericht, 1847. appear on addition of acetic acid. In other parts the ganglia contain corpuscles similar to those already described as occurring in the spinal ganglia, with the exception that they are in general perhaps somewhat smaller. They are
