A POPULAR SKETCH OF INDIAN ANIMALS IN THEIR RELATION WITH THE PEOPLE. By JOHN LOCKWOOD KIPLING, C.I.E. With many Illustrations by the Author. TIMES::-" Mr. Kipling's book is that of a skilled artist as well as a keen observer. He goes through the whole of the fauna of India in its relation to man, illustrating it copiously and effectively with his own and other pencils, including those of more than one native artist." PALL MALL GAZETTE :- -"A volume of animal lore, and a right excellent one it will be pronounced by all those interested in folk and animal lore. Mr. Kipling has managed to compress into 400 pages an unusually large amount of really interesting information. He is scientific without being pedantic, and chatty without ever being garrulous.. The general public will welcome the book chiefly on account of its more amusing and cheerfully instructive contents, and those who expect much will, for the nonce, not be disappointed. The book is full of good stories and of charming illustrations." ST. JAMES'S GAZETTE:-"A book which will give English readers a truer conception of the character of the natives than a whole library full of standard works. It was a happy idea to define the progress and limits of civilization in India by describing the relations between man and beast.... Mr. Kipling is equally clever with pen and pencil. The result is a very charming volume, which is at once entertaining and instructive. . . Of the admirable drawings Of the book itself, we can only repeat that it is one of the best about India we have seen for a long time." we cannot speak too highly. TO H.R.H.

WATSON & SONS, OPTICIANS TO HER MAJESTY'S GOVERNMENT, 313 HIGH HOLBORN, LONDON, W.C. THESE TAPS have been opened and closed under water pressure for the equivalent of more than 50 years (30 times a day) without any deterioration. The ordinary rubber, fibre, or leather washer valve, and the packing or washer around the spindle, are entirely dispensed with. Perfect watertightness is nevertheless attained. By the invention of this indestructible water tap Sir William Thomson, D.C.L., LL.D., President of the Royal Society, &c., the author of many other useful inventions, has effected what previous inventors have unsuccessfully attempted. By an ingenious device the metallic valve and its seat retain their burnished condition for an indefinite period. The taps are made of the best metal throughout, and are equally suitable for boiling and cold water, are tested to 300 lbs. per square inch before leaving the works, and are sold at a lower price than equal qualities of ordinary firms by the PALATINE ENGINEERING CO., LTD., 10 Blackstock St., Liverpool, SOLE LICENSEES.
