NOTES ON RECENT THERAPEUTICS. One of the recent remedies at home in skin diseases ia acid used in the proportion of 1 to 15 of lard. This remedy has been known in India for some time under the empiric name of Goa powder, and used in all cases of skin disease which have shown that were dependant they on a nerve weakness of the part. A good guide for its employment is the annular or serpentine character of the eruption. Dr. Crocker relates a case of bilateral psoriasis which he treated, one side of the body with chrysophanic acid ointment, the other with two drams of turpentine in an ounce of olive oil ; the strength of each preparation was increased until in twelve days pure turpentine was used on thedaily one side, and chrysophanic acid one dram to the ounce on the other The eruption had disappeared from the whole body, with the exception of a few spots, in this time. There was no advantage of one application over the other in any way. Dr. Crocker?is of opinion that any stimulating penetrating application will cure this disease.
a very dangerous generalisation this when the_ bilateral character of the eruption is considered, and one correspondent subsequently writing says that he saw a case of psoriasis (bilateral) cured by liawng the one aim treated with chrysophanic acid, and the other simply wrapped in cotton wool. One may call to mind the experiment conducted with 4 clinical thermometers in connection with this latter case. One thermometer being held in either hand, and the other two one in either axilla.

the second remedy were afterwards applied to the opposite Bide, then how much can be put down to the central cure already worked from the other side, and how much to the efficacy of the second drug ? Two cases as nearly similar as possible must be taken, and careful and complete notes taken of each, and then they can be compared. *
The new mechanical method of relieving pain, as explained and described bv Dr. Mortimer Granville, is one which bids fair to systematise the treatment of those distressing cases of neuralgia which have long been the dread of physicians. They have mostly gone empirically and haphazardly to work with the recognised specifics,?Quinine, Iron, Croton Chloral, Nitrite of amyl, etc., and have flattered themselves with a cure, when it is very doubtful if they had anything to do with the matter. The principle of the matter is exceedingly simple, and, as Dr. Granville says, only wants development Pain is an abnormal rhythmical action to be very useful. in a nerve and communicated to the sheath of the nerve which causes the sensation.

Medicine is a rather grim subject, and it is but rarely one pets a chance of a laugh out of a journal connected with, and devoted to it, but your advertising columns supply the place of a facetious column, ' vide Lamplough's pyretic saline. One authority says it unfolds germs of immense benefit to mankind,' another evidently has had scarlet fever in his experience, a third must consider it a truly heavenly medicine, for ' since its introduction the fatal West-Indian What deep hidden fevers are deprived of their terrors.' meaning is contained under Rawul Pindee's observation 'I gib's it up.'
