Van Gehuchten, A. La dégénérescence dite rétrograde ou dégénérescence

Wallérienne indirecte. Le Návraxe, Vol. V, Fasc. I, pp. 1-106, April, 1903.

An extensive review of the literature on Wallerian degeneration, followed by experimental studies on degeneration of peripheral and central neurones. The degeneration which occurs between the point of section and the perikaryon is cellulifugal and therefore typically Wallerian. For this phenomenon the author proposes the same "dégénérescence wallériene indirecte.” It occurs in both the central and peripheral systems. In the former, certain fiber tracts undergo only direct degeneration while others undergo both direct and indirect degeneration. The author insists that it must be known exactly which tracts undergo indirect degeneration before the degeneration phenomena can be accepted as trustworthy evidence on certain physiological questions.

The forebrain was removed from fifteen turtles and the forebrain and thalamus from fifteen. After about three months degenerated fibers can be demonstrated by VASSALE's modification of MARCHI'S method, these being confined to the brain if the forebrain only has been removed, but extending through the whole length of the spinal cord if the thalamus also is removed. This fasciculus thalamo-spinalis is diffusely scattered through the fasc. longitudinalis medialis.

C. J. H. Langley, J. N. On the Effects of Joining the Cervical Sympathetic Nerve

with the Chorda Tympani. Proc. Roy. Soc., LXXIII, No. 489, Feb. 24, 1904.

In this very brief preliminary communication it is mentioned that the cervical sympathetic and the chorda tympani have opposite effects on the blood vessels of the submaxillary gland, the former causing contraction of the vessels and the latter dilation. Two experiments were made

on cats to determine whether the cervical sympathetic, if allowed an opportunity to become connected with the peripheral nerve cells in the course of the chorda tympani, will in part change their function from vaso-constrictor to vaso-dilator. The superior cervical ganglion was excised and the central end of the cervical nerve was joined to the peripheral end of the lingual, which contains the chorda tympani fibers. After allowing time for union and regeneration of the nerves, the cervical sympathetic was stimulated; it caused prompt flushing of the submaxillary glands, and the effect was repeatedly obtained.

The experiment is interpreted as showing (1) that vaso-constrictor nerve fibers are capable of making connection with peripheral vasodilator nerve cells and becoming vaso-dilator fibers, and (2) that whether contraction or inhibition of the unstriated muscle of the arteries occurs on nerve stimulation depends upon the mode of nerve ending of the post-ganglionic nerve fiber. The cervical sympathetic gave a less scanty and more prolonged secretion than normal, so that some of its nerve fibers had become connected with the peripheral secretory nerve cells of the chorda tympani.

C. J. H. Carlson, A. J. The Rate of the Nervous Impulse in the Spinal Cord and in

the Vagus and the Hypolossal Nerves of the California Hagfish (Bdellos. toma dombeyi). Amer. Jour. Physiol., Vol. 10, pp. 401-418, 1904.

By the use of a graphic method the rate of nerve transmission was determined. Electrical stimulation served to initiate the impulse. In the spinal cord the impulse moves antero-posteriorly, with but slight individual variations, at the rate of 4.50 m. per second. The rate in the opposite direction' is 2.50 m. per second, and it is more variable as well as slower than the rate for transmission in the anteroposterior direction. The vagus shows a rate of about 2.50 m., and the mandibular of 4.50 m.

The fibers of the cord as well as those of the peripheral nerves in the hagfish are non-medullated. As the author remarks, this low form of fish has slower transmission in the spinal cord than have certain of the annelid worms in the ventral nerve cord. Furthermore, “the rate in the peripheral motor nerves is the lowest recorded for any vertebrates and even lower than that in the motor nerves of some of the molluscs.”

This paper is of value because of its suggestions of possible applications of the reaction-time method in the study of the physiology of the nervous system, as well as for the interesting facts which it presents. Attention is called to evidence in the results of the experiments described “that the rapidity of the processes of conduction in
