1. This chemical seems to have no injurious effect upon animal cells.

2. It has a very energetic destructive action upon vegetable

cells—microbes.

3. It has no toxic properties; five cubic centimetres injected beneath

the skin of a guinea-pig do not produce any serious result, and it is

also harmless when given by the mouth.

As an immediate conclusion resulting from my experiments, my opinion

is, that peroxide of hydrogen should be used in the treatment of

diseases caused by germs, if the microbian element is directly

accessible; and it is particularly useful in the treatment of

infectious diseases of the throat and mouth.

Address, "Dental Student," 1100 Burlington street, Muscatine, Iowa.

SIR JOHN TOMES is spending his declining years very comfortably and

pleasantly at his delightful country home, Upward Gorse, Catram Valley,

and devotes a great deal of his time to the literature of the day, and

is remarkably strong and well preserved for a man of his age.

THE TOOTH TRANSPLANTED from a bell-boy's mouth to a lady's, the full

description of which is given in the _Missouri Dental Journal_ of

1882, on page 245, was extracted a few days ago, having done faithful

service in its transplanted socket for _ten years_, lacking one month.

The roots were considerably absorbed; also the external plate of the

socket, which made it unfavorable to implant another tooth, so a

"dummy," attached to a gold crown on an adjoining root, was substituted

in its place.
