cord and brain. 
A Woman with Four Breasts . — A primiparo us woman was admitted under 
M. Lorain, and was delivered next day of a dead premature child. She 
was found to have four breasts, two in the normal position and with the 
normal puerperal appearances, and two which, from their position, might be 
called axillary, and attaining the size of a small orange . — Revue photograph ique

Permanganate of Potass in Coryza . — We desire to call attention to the use 
of permanganate of potassa in very dilute solution (0-18 grins. =1*67 grains 
to 60 grms. or c.c.=to about 2 fluid ounces) against coryza, cold in the 
head, attended with severe sneezing. Of the permanganate solution, some 
twenty to sixty drops are poured into a tumblerful of water, and of this 
liquid every two hours a quantity of a tablespoonful is snuffed up the 
nostrils j and if there be any soreness of the throat, the same liquid is applied 
as a gargle. Dr. Franck, of Munich, states that he has prescribed this 
mode of treatment now for some years, and found it very efficient, by curing 
the complaint in about from two to four days. 
Skin Grafting . — This remedy now appears quite successful. The u Medical 
Press ” of November 30 says that Mr. Pollock exhibited to the Clinical 
Society several cases of the operation devised by M. Riverdin, of Paris, in 
1869. A girl, aged eight, had been in St. George’s Hospital with an ulcer- 
ated surface from buttock to knee, which had existed for two years. Mr. 
Pollock first transplanted two small pieces of skin, about the size of millet 
seeds, taken from the lower part of the abdomen. Fourteen pieces in all 
were transplanted at various periods. The burn was nearly healed in five 
months, without any perceptible contraction of the cicatrix. Mr. Pollock 
transplants usually very small pieces, and takes care that the granulations 
are healthy where he inserts them. Mr. Lawson showed a patient in whom 
a large ulcer in the leg had resisted all treatment for four } r ears, and was 
completely cured in four weeks after a piece of skin, the size of a fourpenny- 
piece, had been planted on it. As soon as the new skin had established 
its vitality, granulations sprang from the circumference, and rapidly closed 
in the wound. The granulations should be healthy, no fat transplanted, 
but only skin, which must be accurately applied to the granulating surface. 
The new skin is kept in position without interruption, and lightly covered 
with a layer of lint, over which is a small compress of cotton wool and a 
bandage, for the purpose of keeping it warm until it grows on to the part. 
The Indian Medical Service . — We regret to state that there will be no 
February examination this year. 
Urea formed in the Liver . — According to a note in the u New York 
Medical Journal” for November, the latest researches upon the place of 
origin of urea, and especially the beautiful experiments of M. Grehant, 
have demonstrated that the kidneys are by no means secretory, but purely 
excretory, organs for urea. Dr. Cyon, in the last number of the u Central- 
Llatt,” publishes a few facts in the form of a provisional communication, to 
show that it is probably produced at the liver. The plan of experimentation 
adopted (in common with M. Istomin) was as follows : The whole of the 
blood was abstracted from the carotid of a dog, and a portion, after being
