Schaffner* has also ob- served ganglionic corpuscles from which nerve-tubes proceeded, in the substance of the lymphatic glands. Small ganglia have also been described by Remak as occurring on the nerves distributed to the bronchi: they have also been observed by Kolliker. The latter observer believes that he has seen nerve-tubes arise from them. From the observations of Purkinje* it would appear that numerous fibres of the sympathetic pass to the cerebro-spinal mem- branes. In the dura mater of the cranium he describes the nerves as most abundant in the neighbourhood of the trunks of the three meningeal arteries. Most of them accom- pany the vessels ; but there are also others which leave them and ramify in the mem- brane. In the pia mater of the cerebellum the nerves which branch separately from the arteries are not so numerous as in the pia mater of the cord. The nerves in the pons and cerebrum belong exclusively to the ar- teries : no trace of nerve-fibres was seen in * Vcrmischte Bcobachtungen in Henle und Pfeuffer's Zeitschrift, band vii. p. 177. t Miiller's Archiv. 1845. the choroid plexuses. Around the vena Galeni magna they form a dense plexus which passes into the tentorium cerebelli, and seems to belong to it rather than to the venous system. The nerves in the pia mater of the cord unite with th
