    Grey neurine a ganglion—white neurine a nerve Grey generates, white conducts power : e. g. nerves and com¬ missures are conductors to and fro; the commissures are organs of comparison—grey neurine the seat of judgment, &c.

Spinal cord, 40—43 Not the seat of sensation, nor of voluntary or instinctive motion Analogy between articulata and vertebrata Symmetrical nerves of Sir C. Bell, the analogue of the spinal cord of the vertebrata Nervous thread of the lower is rudimental of the spinal cord of the higher Whenever the rudimental thread of the lower terminates in, or is joined to, a grey ganglionic centre or brain, then there is volition Comparative anatomy works out the analysis of the functions in man 4. Tunicata, 43—45 Simply vegetative life Elastic coating, the analogue of the valvular conchifera In structure a mere sac, with oral and anal openings, guarded by sphincters Rudimental lungs or aerating sur¬ faces Self-procreation by germs Elastic coating, contractile The ganglion with nerves radiating to the sac and its sphincters Tentacular filaments fringing the branchial orifices—nerves of sensation The sphincters act from consent or sympathy, analogous to the sphincters in man 5. Conchifera, 46, 47 1. The oyster a. No locomotive power b. A particular muscle for closing its shell c. Rudimental organs of vision d. One ganglion or nervous centre, the analogue of the medulla oblongata, governing its respi¬ ratory and oral apertures e. The smaller ganglia, analogues of the cerebral ganglia in man —organs of sense 2. Shell-bearing molluscae a. Locomotion b. Rudimental foot implies addi¬ tional vesicular neurine — the pedal ganglion i. Brain—consciousness 5 ii. Medni. oblong, excito- ! motory and respiratory j functions iii.
