The cyclopædia of anatomy and physiology cyclopdiaofana03todd Year: 1847 Second abdominal ganglion of a greenfinch, slightly compressed under the compressor. The course of the nerve-tubes only is represented, a, fibres passing in ; b, emerging fibres ; c, sur- rounding fibres. The meshes for the reception of ganglion globules are shown. Fig. 374. A small piece of the otic ganglion of the sheep, slightly compressed, showing the interlacement of the inter- nal fibres and, the grey matter. (After Valentin.) tin, travel round the margin of the ganglion, and to these he gives the name of umspinnende Fasern, surrounding fibres, and some fibres pass from them to the more central ones, or from the latter to the former. Nerve-vesicles exist at the circumference of the ganglion as well as in its interior, and to them is due the peculiar grey colour of that body. The best mode of examining these points is to select the smallest ganglia of very small animals, birds, mice, &c.; these, when sub- jected to compression, become very transpa- rent, and display much of their intrinsic ar- rangement. Or thin slices of large ganglia may be placed under the microscope, and when torn up by needles the disposition of the nerve- vesicles and the caudate processes, when pre- sent, are rendered visible. And none is more suitable for this purpose than the Casserian ganglion of the fifth nerve, which by the ab- sence of a dense sheath and its greater loose- ness of texture is more easily examined. It is a highly important problem, in minute
