    is the reflex tonus of the spinal cord. (Cf. also “Lancet,” 1881, vol. ii. p. 83.) The average rhythm of tremor and clonus is 8 to 10 per second. Tendon a'second} AAAAAAAAAAAAAAAAAAAAAAArmAAAAAAAAnyW'yVWm Comparison between the stimulus-to-eontraction intervals observed, with percussion of the Ligamentum Patellae (Tendon) and with direct electrical excitation of the Rectus Femoris (Muscle). Man. YI. Nouvelles Experiences sur les Phenomenes nommes Reflexes Tendineux (with Dr. J. L. Prevost). Revue Medicate de la Suisse Romande, 1881. Four experiments on rabbits made conjointly with Dr. Prevost to test the objection that crossed reflex proves the phenomenon not to be a direct response. Percussion of the knee of a limb of which all nerves are cut causes contraction of the opposite limb, i.e. direct excitation of the opposite limb by vibrations transmitted along the bones. VII. Sur le Temps perdu de la Contraction d’ouverture. Archives de Physiologie, 1882, p. 383. The anodic break contraction (upon man) has a latent period O'04 longer than that of the katliodic make contraction. An anelectrotonic depression of excitability may last for 0'05 second after cessation of the polarising current. Comparison between the stimulus-to-contraction intervals by closure (c) and by opening (o) of a galvanic current. Median nerve. Flexors of the fingers.
