contributors, who calls Uranus not worth looking at, except with 

 very large telescopes, should not be attended to. A good 3-inch 

 glass gives an image of this planet which it is very interesting to 

 contrast with that afforded by any small star. 



New Entozootic Malady : Observations on the Probable Intro- 

 duction of this Formidable Disease, and on the almost inevitable 

 Increase of Private Diseases in general, as a Consequence of the 

 Proposed Utilization of Sewage. By T. Spencer Cobbold, F.E.S., 

 P.S.L. (Groombridge.) — We recommend attention to Dr. Cobbold's 

 " Entozoa," a work which embodies an immense collection of 

 information relating to parasites. The utilization of sewage cannot 

 be stopped by an alarmist pamphlet, but the knowledge conveyed in 

 Dr. Cobbold's important treatise cannot be too widely diffused, if 

 the great evil of parasitic disease is to be kept down. 



Functional Diseases of the Stomach. Part I — Sea-sickness ; 

 Its Nature and Treatment. By John Chapman, M.D., M.R.C.P., 

 M.Bj.C.S. (Triibner and Co.) — The discovery that the sympathetic 

 nerve causes contraction of the blood-vessels led Dr. Chapman to 

 believe that, by exciting or diminishing its action, he could diminish 

 or augment circulation, and thus obtain a remedial power over 

 certain disorders. Experiment verified his anticipations that cir- 

 culation could be increased by applying cold to the back, and thus 

 diminishing the contractile action exerted by the sympathetic on 

 the arterial vessels. Dr. Chapman first employed his process on 

 epileptic patients, and he now recommends a sausage-like bag filled 

 with ice, and laid down the spine, as a cure for sea-sickness. Many 

 cases are mentioned of the success of the plan, and the patients 

 describe it as less uncomfortable than would be supposed. Perhaps 

 a more complete study of narcotics will enable the same result to be 

 accomplished by the aid of some substance having a specific action 

 on the sympathetic system. 



Heat Considered as a Mode of Motion. By John Tyndall, 

 E.R.S., etc., Professor of Natural Philosophy in the Royal Institu- 

 tion, and in the Royal School of Mines. Second edition, with addi- 

 tions and illustrations. (Longmans.) — We are glad to welcome a 

 second edition of this admirable work, which is increased by some 

 seventy pages of new matter, embodying researches completed since 

 the publication of the first edition. It is undoubtedly one of the 

 most valuable and profound books which this generation has pro- 

 duced. And the learned professor deserves great praise for avoiding 

 the besetting sin of ordinary scientific men, who seem to fancy that 

 their reputation for wisdom will be increased by the dryness of their 

 style and the number of unintelligible words they employ. Pro- 

 fessor Tyndall is eloquent, simple, and clear, exemplifying the double 

 genius of discovery and exposition. 



The Old City and its Highways and Byways : Sketches of Curious 

 Customs, Characters, Incidents, Scenes, and Events, illustrative of 

 London Life in Olden Times. By " Aleph," author of " London 

 Scenes and London People." (Collingridge.) — This is another of
