KNOWLEDGE & SCIENTIFIC NEWS.

himself half seas over in dry nips all alone, without any other 

 diversion, so I sat down and talked to hini about evorythinj; 

 I could think ot. At first he was very unich taken up with his 

 arm, but from that we went on to the expetlition in .i;eu< ral, 

 then to shootins; iu general, and lastly, after inuumerabli! ex- 

 cursions landed, in the Lofloden Islands iu which he was 

 patriotic.dly interested. In this way I brought him little by 

 little into brilliant spirits. He grew livelier at every dram. 

 Fosheim and Simmons, who had been chosen for the deed of 

 bone-setting, sat awaiting the propitious monieni, following 

 with much excitement his various st.ages of development 

 during om- potations, while I t.alked myself blue in the face to 

 get him to drink more and hark on the crisis. It was not long 

 before Olsen himself began to be highly pleased at the whole 

 performance, decLaring it was the most amusing entertainment 

 he had ever t.aken part in. When he had swallowed about 

 half a bottle of brandy we thought he must be about ripe to 

 be taken. We accordingly placed him on a chest, and the 

 bone-setters began their work, but no, the collar would not go 

 in at last, however, we heard with unspeak- 

 able relief the crack of the arm .as it slipped into its socket. 

 As for Olsen. notwithstanding all he had taken tiown, it h.ul 

 not much eflfect on him. While we were doing our work, the 

 pain and excitement h:id kept him sober, but the instant 

 the ann was in its .socket he became dead drunk." The 

 operation in the result proved quite successful. We have not 

 space for further extracts from this deeply interesting book. 

 We may say of it in conclusion that its interest and value arises 

 from its es-sentially human aspect. Even the dogs become the 

 reader's as well as the writers friends ; and Sverdrup gives us 

 some quite new views about the l-^skimo. In short, he is a 

 shrewd observer, a kindly critic, a good writer, and a man to 

 the backbone. His book is worthy of him. 



Zoological Notes for instruction in schools, of a kind which 

 is likely to attract as well as to instruct children, are being 

 published by Messrs. .-Vslier and Co., of Coveut Garden. The 

 plates, large in size and printed in colour, are ( ierman in origin 

 and manufacture (Schroder and Kull's P>iological diagrams) : 

 and if, on the one hand, they are w.anting in artistic feeling, 

 the amount of information they convey of the characteristic 

 surroundings, occupations, attitudes, anatomy and allied 

 species of the animals pourtrayed is surprising. It is probable 

 that such plates leave a stronger impression on a childish 

 mind than others more artistic or more photographic. 



"Our Country's Animals" (Simpkin, Marshall, Hamilton, 

 Kent and Co.), by W. J. Gordon, is one of a very use- 

 ful popular series of Natural History. Each volume is 

 illustrated with coloured plates, so that the amateur observer 

 of Nature in country rambles may be able to identify the stoat 

 that runs across his path, the field-mouse that rustles away 

 into the hedgerow as he passes, or the water-rat that his 

 coming startles into diving from the bank into the stream. He 

 may learn, besides, something of their species, habits, and 

 characteristics. 



"The Nature Library" (Fisher Unwin). "Quiet Hours with 

 Nature," by Mrs. Brightwen, is in p<art republished from the 

 " Girl's Own Paper." The author's loving observations of bird 

 and insect life are prettily and sympathetically recorded ; and 

 her book is as pleasant to read as it must have been to write. 



"Nature's Story of the Year." by Charles A. Witchell, of the 

 same series, also records his observations of Nature, though in 

 a less sympathetic spirit. No true lover of Nature could shoot 

 a bullfinch in cold blood because it attacked his fruit trees. 

 His book nevertheless contains much that is interesting. 



" A Modern Zoroastrian " (Watts and Co.), by Samuel f^aing, 

 deals with scientific and moral questions, and proceeds from 

 the study of ether and energy to consideration of religions and 

 philosophies. It is addressed to the general reader. 



"Ethics of the Great Religions " (Watts and Co.), by Charles 

 T. Gorhani, is a useful survey of the principal religions of the 

 world, and the features they have in common. 



"The Ethics of the Dust" (George Allen, pocket edition). In 

 this little book, which was written in the form of graceful and 

 fanciful conversations with children, Kuskin attempted to ex- 

 plain some of the principles of mineralogy and to awaken an 

 interest in the study of the subject. 



"The Lion Hunter" (John Murray), by Hon. Aleyn Gordon 

 Curnming, which appears in a new edition, is the record of five 

 years' adventures in the interior of South Africa, covering a 

 period which began as long ago as October, 1843, so that the 

 writer traversed much of what was then unknown country. 



BOOKS RECEIVED. 



(ieography, — We have received lor review the iiiiietietli 

 edition ot Dr. J.uues Cornwcll's " School Geography ' (Simp- 

 kin, Marshall, Hamilton, Kent, and Co.). This coiii|)reheiisive 

 and clearly-arranged text-book should be useful to (enclicrs. 

 Its facts ;irc judiciously select<'il. and tlie information given 

 about each country is divicU'd imdrr the heads of physical atid 

 political geography so that the tcachci's work is simiilificd as 

 f.ir .IS possible. 



fieography for Beginners (Simpkin, Marshall, llaiiiiltou, Kent, 

 atul Co.). bv the same author, contains (he principal facts in a 

 simplified form. 



Photography.— Practical Enlarging (lliffe and Sons), by John 

 A. Hodges, appears in a sixth edition. It is intended for the 

 use of hand camera workers, or those who make use of .iny 

 small cameras. Bromide enlarging, as tlie most popular 

 method, is very fully dealt with, and full directions arc also 

 given for the more el;d>orat<' methods of making enl.irged 

 negatives. 



Practical Slide Making lllilfc and Co.), by G. T. Harris, 

 F.K.I'.S., is intended to supply trustworthy information con- 

 cerning all the best known methods of making lantern slide 

 transparencies; it is clearly written, aiul well adaptc<l lor 

 pr.actical purposes, with good print and a strong binding. 



Photography. — Mr. W. Jerome Harrison's " Photography 

 for All" (lliffe and Sons) suifers from the defects of its 

 qualities. It is designed for the instruction of thosf! — among 

 others — who handle a camer.i for the first time; and it is 

 sometimes too elementarj'. This would not be a great defect 

 if it were uj) to date; but that it is not, and the ways it 

 recomnutids of doing things .-nc not alwavs the best ways. 



The Photographic Dealer's Annual (Marshall, Brookes and 

 Chalkley) is what it aims .at bring — largely .1 trade |)ul)lii-atioii. 

 But its articles are well written and to the point ; and it is 

 an extremely useful "who's who" and "what's what" to the 

 practical [)hotographer. 



Engineering. — The Model Engineer Series (IVrcival Marshall 

 and Co.) is a series of cheapl)' printed and fully illustrated 

 popular handbooks ; price, fxl. each. 



The Locomotive is a simply-written introduction to thi^ study 

 of locomotive engines, distinguishing between their dilTerent 

 types ami explaining them. 



' X-Rays, by K. F. Howgrave-Graham, A.I.E.IC, aims .it giving 

 the student some idea of the course of (■x])erinnnt and dis- 

 covery which led to the present state of scientific knowledge 

 of Kimtgen rays. 



Static Electricity, by Percival G. Bull, M.A.,Oxon., describes 

 simple experiments illustrating electrical laws and phenomena, 

 and deals with the various means of producing elfctricity ; and 

 with electrical attraction and repulsion. It is designed for the 

 use of young students, and is very clearly and simply written. 



Patents Simply Explained gives directions for the patenting 

 of inventions and the registration of trade marks and designs. 



Mechanical Drawing, by F. E. Powell, is designed as a guide 

 to the apprentice or student, and describes the use of drawing 

 instruments, and the "reading" of drawings; it also gives 

 directions for preparing practical illustrative sketches. 



Acetylene Gas, by Cyril N. Turner, is a practical handbook 

 on the uses .and generation of .acetylene gas ; and is designed 

 to enable amateur meclianics to produce it in an inexpensive 

 way. 



We have received from Mes.sr.s. Adam Hilger, Ltd., 

 their new list of .spectroscopes ;md spectroscopic 

 accessories. The list is well and conveniently arranged 

 antl the information it affords concerning spectroscopic 

 instruments alike for general and for special work is of 

 practical service to the investigator. The most inter- 

 esting pages are those which reproduce lilm replic.-is 

 of Rowlandson's diffraction gratings, which are ruled 

 with 14,438 lines to the inch — a m.arvel of scicntillc 

 handicraft ; and of the Michelson echelon diffr.ution 

 gratings.
