Schaffner also describes a bipolar cell in the ganglion Gasseri of the sheep ; and similar cells have been observed by Cord* and Pappenheim in the acoustic nerve of the pig, and by Frey in the Gasserian ganglion of the cat. In the common trunk of the pneumogastric and sympathetic nerves in the middle of the neck, in the young calf, oval cells may be seen which have distinctly attached at their peripherical extremity a nerve-fibre ; and some of them also appear to be connected with one at the opposite or central extremity. The different cells composing a ganglion are each surrounded by a more or less clear, homo- geneous substance, in which are contained a number of round or oval nuclei. These are seen to form a single or double row around the margin of the ganglionic vesicle, their long axis being directed in the axis of the cir- cumference of the cell (fig. 288.)- They are also seen upon the surface of the corpuscle (c, 288.). This substance not unfrequently presents a more or less fibrous aspect, as if composed of spindle-shaped corpuscles. It re- sembles much (as has been already stated) the fibres of Remak. The nuclei measure from the rJj_th to the 4-oVoth of an inch in breadth, and about ^n^th to -f^th of an inch in length. The structure in question is closely connected * Kolliker's Mikroskopische Anatomic, band ii. \ 519.

It has been termed the capsule of the ganglionic corpuscle. The cap- sules surrounding the different ganglionic cor- puscles are also closely united to each other, so as to form a kind of framework, in the loculi of which the ganglioni
