Major MacMahon recently delivered an inter- 

 esting address at the Royal Institution upon the 

 '• Magic Square," which is an association of numbers 

 airanged in rows on the principle of the chess- 

 board ; these added any way produce the same 

 multiple. It is an old-world game of a scientific 

 character, and one that becomes interesting to 

 those who learn its rules. These, we understand, 

 are taught in one lesson by Mr. C. M. Wray, 

 65 Warwick Street, S.W. 



Experiments by Balloon, conducted by Drs. 

 Hallion and Tissot in Paris, are reported to have 

 given very interesting results. The object of Drs. 

 Tissot and Hallion was to discover the cause of 

 mountain-sickness, and the feeling of nausea some- 

 times felt by aeronauts. The question before them 

 was whether, as held by the school of Jourdanet 

 and Paul Bert, this was due to the poverty of the 

 atmosjhere in oxygen, or whether this feeling of 

 nausea was caused by an interference with the 

 circulation of the blood. Drs. Jolly and Bounier 

 in a second balloon, and the other doctors in a 

 third, intended especially to devote themselves to 

 a spectroscopic examination of the blood, to the 

 observation of the globules of the blood, to a study 

 of the causes of giddiness and of altered respira- 

 tion in mid-air. When on the ground a milli- 

 metre cube of human blood contains about six 

 millions of red corpuscles ; at the height of 4,000 

 metres thfse increased to ten millions. It was 

 hoped, in the event of a real increase being observed, 

 anaemic people would be benefited by being sent 

 up in balloons, with the resulting increase in the 

 number of corpuscles in their blood. The observa- 

 tions made, however, tended to show that this 

 neo-formation is only apparent. The effect on a 

 rabbit which had been taken up showed that at a 

 certain height the organism loses a definite quantity 

 of water, whilst the blood becomes concentrated. 



NOTICES BY JOHN T. CARRINGTON. 



The Discoverij of the Future. By H. G. Wells, 

 B.Sc. 95 pp.. 1\ in. x 5 in. (London : Fisher 

 Unwin&Co. 'l902.) 2s. 



This little work is the reprint of a lecture 

 given by the author at the Royal Institution on 

 January 24th of the present year. It is practically 

 a continuation of his recently published work 

 " Anticipations," dealing, however, chiefly with the 

 ethical side of the problems of the future rather 

 than the mechanical. 



A Concise Dictionary of Egyjriian Archaeology. 

 By Mary Brodrick and Anna Anderson Morton. 

 viii -I- 198 pp., 7 in. X 5 in., with 80 illustrations. 

 (London : Methuen & Co. 1902.) 3s. 6d. 



Now that Egypt has become a fashionable play- 

 ground for Britons, a better knowledge of the 

 hieroglyphic characters found on the ancient monu- 

 ments is almost a necessity for full enjoyment. 

 Herein they are illustrated in alphabetical order, 

 as are many cartouches and other interesting- 

 subjects. It is a useful little book. 



The West Indies and the Empire. By H. de R. 

 Walker, x + 253 pp., 9 in. x 5^ in., with map. 

 (London : Fisher Unwin. 1901.)^ 7s. 6d. 



This book refers chiefly to the economic and social 

 conditions in the West Indies in recent times. It 

 is the result of a visit paid by the author to that 

 beautiful part of the world, and will be found of 

 interest to the increasing number of persons who 

 make a winter's sojourn under the sunny skies of 

 the Antilles. There are only touches here and 

 there with regard to scientific subjects, as may be 

 gathered from the following quotation from the 

 author, who says, when referring to the botanical 

 departments of Jamaica: "I mention the fact 

 because there may be many, like myself, who con- 

 nected Kew simply with the idea of well laid-out 

 gardens which were thrown open to the public, and 

 knew nothing of the serious scientific researches." 

 One may learn much by travel. 



Moths and Butterflies. By Mary C. Dickerson, 

 B.S. xviii -I- 344 pp., 9^ in. x 6^ in., with 234 

 illustrations. (Boston, L'\S.A. : Ginn & Co. 1901.) 

 10s. 6d. net. 



It has seldom been our pleasure to notice such 

 a beautifully produced book as this before us. 

 Splendidly illustrated by upwards of 200 photo- 

 graphs by the author from life, it forms quite a 

 work of art, and is highly creditable to the pub- 

 lishers, being also among the best examples of 

 American typography. The subject-matter is 

 p^^rely popular, but apparently accurate, the 

 examples being taken chiefly from New World 

 species. It contains little about classification, but 

 is a good story of moths and butterflies for 

 young people and some others. English names 

 are used for most insects ; but the many readers 

 who, after meeting with this book, will first com- 

 mence to collect and then study, may later learn
