MEDICAL AND SURGICAL NOTES.

THE EYE UNDER GALvANIC CURRENTS-The
physiological action OF electric currents and discharges
has been made matter OF extended study by ITO
fesor Dubois Of Berne and, in giving an account OF
his researches in this direeon some interesting OBJ
servations are presented the human eye which, IL
is known has luminous sensations under the action
of galvanic currents sudden variations OF current
strength says Professor Dubois especially at making
and breaking the circuit. produce flashes, and with

SPECIAL APPLICATION OF SULPHUR IN DIPH
THERIA-In the local treatment of dphheria situated
above the Iarynx DR.. +. n. Drake directs attention.
In 1.-The Medical News to the great advantage OF pre-
serving the false membrane long as it Will remain
In its place-he dphtheretic membrane answering ad-
mirably, after nonirritatDg disnfectant has been
applied over IT, TO retain the medicament used and to
dress the diplheretic spots in the mucous membrane
beneath the false membrane may be dlsnlected by
irrigation with solution Of any OF the soluble dis
inectans, and the medicament afterward applied to
the diseased should be slow of solution or in
soluble. DR.. Drake has found washed sulphur TO act
well for this purpose-insufiated, or applied with
OF absorbent cotton, wound on the end OF SUCK
or with a large comellair pencil if well packed into
the meshes of the membrane, from three to five APP
pcati0ns in the twenty -four hours suhce, or twice
during that time in mid Patients old enough
sulphur has been applied that their Threats feel better
Probably the sulphur, while in the meshes of the
moist fresh membrane takes up oxygen and sets
free sulphurOus acid.
