Sir,
The mistake of the printer in substituting the word "every" for "even," in the paper on Vaccination (p. 40), so materially affects the sense of the passage, that I must request the favour of the following insertion:—

"3d. That while the vaccine cicatrix retains even one distinct fovea or depression, the individual continues unsusceptible both of small pox and of re-vaccination; but that," &c.

I am, Sir,
Your obedient servant,
Thos. H. Burder.

SINGULAR BICEPS MUSCLE.

To the Editor of the London Medical Gazette.

Sir,
The valuable paper communicated to your Journal, by Mr. Stanley, last week, has brought to my recollection a singular appearance of the parts in front of the shoulder-joint which I dissected about two years ago. It is a fact worth recording; and perhaps you will be kind enough to insert it in your next number.

The circumstance was this—that in the right arm, instead of there being a biceps muscle having two origins, the one the shorter from the corocoid process, the other the longer from the upper part of the glenoid cavity of the scapula, there was simply a one-headed muscle arising from the corocoid process. I could find no tendon passing through the joint answering to the long head of the biceps, neither was there any appearance of a biceptical groove; the capsular ligament was, perhaps, thicker than it is found in ordinary cases.

I knew nothing of this man during life, and am therefore unable to give any account of the use which he made of this arm.
