glass tube in a current of dry hydrogen. The purity was determined by analysis, the melting point being found to be 720° C.-On the transmission by ticks of spirillosis and Laveran of bovine piroplasmosis: A. and M. Vallée. A specimen of the larva of Rhipicephalus decoloratus forwarded by M. Theiler from Pretoria, and stated by him to be the cause of the transmission of spirillosis in cattle, was allowed to act upon a healthy cow, with results entirely confirming those of M. Theiler. -The evolution of the Tertiary mammals: Charles Depéret. Magnetic observations at Tananarivo: P. Colin. Tables are given showing the results of measurements of magnetic declination, inclination, and the horizontal component taken weekly between May, 1904, and April, 1905. The principles of anallagmatic geometry: A. Demoulin.-Some new experiments on the lifting power of the helix "M. Léger at the oceanographic museum at Monaco: M. Léger. The apparatus proved capable of lifting a man, together with a weight representing its motor and the petrol necessary for an experiment of one hour's duration.-A new mode of application of the Pitot-Darcy tube to the measurement of the velocity of water in pipes under pressure: H. Bellet. The modification suggested is the use of a two-fluid manometer, water and a liquid of density slightly greater or less than that of water; carbon bisulphide tinted with iodine gave the best results.-The magnetic properties of the simple element of pyrrhotine: Pierre Weiss.-On a property of the tin-aluminium, bismuth-aluminium, and magnesiumaluminium alloys: H. Pécheux. The action of oxygen upon cæsium-ammonium : E. Rengade. The rapid oxidation of cæsium-ammonium dissolved in an excess of ammonia gives the oxides Cs,O,, Cs,O,, and Cs,O,, all in microscopic crystals. If the oxygen is added gradually a secondary reaction takes place, the amide and hydroxide of cæsium being formed.-Pyranic phenols: R. Fosse and A. Robyn.-On a new reagent for aconitine: E. P. Alvarez.-On the expansion and density of some gases at high temperatures: the application to the determination of their molecular weights: Adrien Jacquerod and F. Louis Perrot. Figures are given for air, oxygen, carbon monoxide, and carbon dioxide on the basis of the nitrogen thermometer at the melting point of gold. The molecular weights based on the density determinations at 1067° C. give for CO and CO, results agreeing within 1/3000th with the results of analysis; for nitrogen, the value found agrees with the atomic weight, 14.008.Osmotic pressure in colloidal solutions: J. Duclaux.-On the coagulation of starch: A. Fernbach and J. Wolff. -On methæmoglobin and its fluorine combination: J. Ville and E. Derrien. The authors maintain the accuracy of their results against the criticism of Piettre and Vila.-Protagon and the cerebrines and cerebric acid preexisting in the nervous tissue: N. A. Barbieri. The author regards the protagon of Liebricht as a mixture of cerebrin and the cerebric acid of Fremy.-On the effects of annular decortication: Leclerc du Sablon. On the results obtained by the observation of arable earths in thin plate A. Delage and H. Lagatu. A reply to various criticisms on an earlier paper. Researches ethnography of the Dravidians: Louis Lapiqus. evolutions of the sexual forms in the soft-water Nereids: Ch. Gravier.-The simultaneous contrast of colours: A. Polack. The phenomenon of the simultaneous contrast of colours appears even when accidental images by the movement of the eye are completely eliminated. Under these conditions the effect of contrast depends on the state of accommodation of the eye.-On the heats of combustion and chemical composition of the nervous and muscular tissues of the guinea-pig, considered as a function of the age of the animal: J. Tribot.-On a new method of protection against the Röntgen rays: J. Bergonié. The principle of the method consists in placing the whole of the arrangements about the patient above the horizontal plane prolonging the anti-kathode, and below this plane the patient himself. The method has proved successful after six months' use.-On the denomination of the supposed agent in syphilis: Paul Vuillemin. The presence of methane in the borings in Lorraine : Francis Laur.Captive balloon ascents carried out over the sea by the Prince of Monaco in April: H. Hergesell.

"We might continue for ever extracting from Dr. Murray's interesting pages. . . . It is quite impossible to do full justice to the many aspects of a work which we warmly commend to our readers. Nothing in its line more valuable and serviceable is to be found."-Notes and Queries.
"An excellent index will render the numerous references of use to the student, while the beautifully printed bibliography which we have tested in many places and not found wanting is a work remarkable not only because of the circumstances in which it was compiled, but for its unique character and intrinsic value."-Saturday Review.
"A work which should, if its precepts are taken to heart, be of great use both to those who have money to give and to those to whom is entrusted the spending thereof."-Lancet.
