 Some interesting experiments have been carried out at Ryde with new arm of defense. The impliment is simply steel shield to be fixed on the muzzle of a rifle as a bayonet is fixed. It covers one superficial fGot, weighs three pounds, can be easily sluDg under the arm and does not ap- pear to be unwieldy.

Ill.,, recently, and for the poison in canned goods generally, All that is known about ptOmaiDes is that they are little "basic bodies or principles" that develop in putrefying meat. and soG1e- times in other substances, though it is not yet determined what conditions develop them most rapidly. Dr. Cyrus Eds0n of New York thinks ptomaines were the iToble with the rich cheese of a Vermont farmer, which poisoned customers regularly when the nights cream was added to the mornings. milk for the cheese vats, but not otherwise. The pu> bile will be more interested to know that the poison beef at Mo- mence was spoiled before it was dried, and was cured by some thrifty butcher ''te save it."
