. The comparative anatomy of the domesticated animals. Horses; Veterinary anatomy. 118 THE LYMPHATICS. Nerves.—Bert and Laffont have demonstrated the existence of vaso-motor nerves in the chyhferous vessels of the Dog. Galvanization of the solar plexus or the o-reat splanchnic nerve, causes contraction of the wall of these lymphatics. (The lynipiiatic spaces surrounding vessels are designated perivmcular canals. Lymphatics originate in lacunae, or spaces between the fibres of the connective tissues, and these are lined by endothelial cells ; they are drained by lymphatic vessels—the arrangement presenting an analogy to the vascular system of insects and Crustacea. Masses of protoplasm—the connective-tissue corpuscles—abound in many tissues, occupying some of the interstitial spaces ; the latter communicate freely with each other, the communication being tubes in the form of small pores or canals. The fluid drained off is the lymph, which passes into gradually enlarging canals.) Lymphatic Glands. The lymphatic glands are ovoid, spherical, or discoid bodies of medium consistency, grey, rosy, or red-coloured, and sometimes quite black, and which at several points intercept the course of the lymphatic vessels. Their number is considerable, and they are rarely single, but most frequently Fig. 394.
