Dr. VINES, Fellow of the Royal College of Physicians, writes, September 19, 1885 Having used Mr. PULVERMACHER'S BELTS for many years, in the course of medical practice, I am in a position to speak of their great value as a curative agent in cases of nervous disease or functional malady where Electricity is likely to be serviceable. I am entirely convinced of their efficacy." Dr. GOLDING BIRD, M.D., Physician, Guy's Hospital, says :-"I can hardly recommend Mr. PULVERMACHER'S INVENTION too strongly to the notice of my medical brethren."

BY THE RIGHT HON. SIR CHARLES DILKE, BART. With Maps. 2 Vols., 8vo, 36s. The Speaker says:-"What first strikes one in the truly remarkable and important work just published by Sir Charles Dilke, on what he calls the Problems of Greater Britain,' is its singular opportuneness. No book has ever appeared more precisely at the moment when it was most wanted. Nothing but gain can come from such cautious consideration as the author has given to us and the other questions that he has opened and explained, in what is undoubtedly, whatever we may find to say on given ortions of it, the most comprehensive, varied, and instructive survey of the British realm outside the three kingdoms that any publicist has yet attempted.' The Spectator says:-"Sir Charles Dilke's very able book. . . . To deal adequately with a book so stuffed with facts, and occupied with so vast a variety of subjects, is utterly impossible even in the course of two notices. All we can do is to fasten upon one or two of the most interesting features.' The Observer says:-This book is one of the most thoughtful and instructive contributions yet made to our political literature by any statesman or writer on public affairs. . . What Sir Charles Dilke has written is really a manual of Imperial statecraft, and it sets forth with the utmost impartiality and precision the conditions under which we are certain to lose, as well as those under which we may perhaps hope to retain, our Empire."

MONOGRAPH OF THE BRITISH CICADE OR TETTIGIIDÆ (FROGHOPPERS AND GRASSFLIES). By GEORGE BOWDLER BUCKTON, F.R.S., Corr. Memb. Acad. Nat. His. of Philadelphia, Memb. de la Soc. Ent. de France. Illustrated by more than 400 Coloured Drawings. In Eight Parts. Demy 8vo. Part I. 8s. No coloured monograph of the British Cicada exists, and it is even believed that no adequately illustrated monograph exists of Propean species. Partly to meet this want, it is proposed to publish eight quarterly parts, each containing on an average ten -chromo plates and letterpress, illustrating the forms, metamorphoses, general anatomy, and the chief details connected with be life-history of this family of insects. The work will contain also short diagnoses of all the British species, about 230 in number, st of which have come under the author's notice, each species being illustrated by one or more coloured drawings. Some account *be given of the curious myths and tales told by ancient Greek and Latin poets, and descriptions will be appended relating to he curious sound-organs possessed by some species, and other subjects connected with the economy of this interesting but difficult group of Rhynchotous insects. Mr. Buckton's name is well-known to entomologists, and this book represents the labour and hservation of many years. ELEMENTARY DYNAMICS OF PARTICLES AND SOLIDS. By W. M.

EDINBURGH, May 31,'89. DEAR SIR,-I have just returned from a six weeks' stay at the Ben Nevis Observatory, and while there had an opportunity of testing the admirable qualities of your new "Watkin" Aneroid. The result has been most satisfactory, the extreme error noted being only about ro of an inch. During my stay at the Observatory the Aneroid was frequently tested by taking it down 2000 feet and then comparing it with the standard on my return. The results obtained speak volumes for the high-class workmanship and great accuracy you have attained in the manufacture of this instrument. (Signed) R. C. MOSSMAN, F.R.M.S., Observer, Scott. Met.
