Jews in China.—A colony of Jews is known to exist in the centre of China, who worship God according to the belief of their forefathers; and the aborigines of the northern portion of Australia exercise the rite of circumcision. Can these colonists and aborigines be traced to any of the nations of the lost tribes?

Derivation of "Mammet."—The Rev. B. Chenevix Trench, in his book on the Study of Words, 4th edition, p. 79., gives the derivation of the old English word mammet from "Mammetry or Mahometry," and cites, in proof of this, Capulet calling his daughter "a whining mammet." Now Johnson,

in his Dictionary, the folio edition, derives mammet from the word maman, and also from the word man; and mentions Shakspeare's

"This is no world to play with mammets, or to tilt with lips."—Henry IV. (First Part), Act II. Sc. 3.

As both Dr. Johnson, the Rev. Ch. Trench, and many others, agree that mammet means "puppet," why not derive this word from the French marmot, which means a puppet.—Can any of the readers of the "N. & Q." give me a few examples to strengthen my supposition?
