of which is at rest : A. Korn, — A particular case of the 

 problem of n-bodies : Thadee Banachiewitz, — The exact 

 significance of Carnot's principle : Louis Fredey. — 

 Lsvorotatory lactic acid : E. Jungfleisch and M. 

 Godchot. /-Lactic acid is much more easily transform- 

 able than the d-acid into the (d + l) acid, and increased 

 care in working is in consequence necessary. The crystal- 

 lised kevo-acid melts at 27° C, at approximately the same 

 temperature as the dextro-acid. — The cysts of Glceosporium 

 and their rile in the origin of yeasts : P. Viala and 

 P. Pacottet. — Stellosphaera mirabilis, a new larva prob- 

 ably belonging to an abyssal form : R. Kcehler and C. 

 Vaney. — The recuperative effects of raw meat after fast- 

 ing : Charles Richet. Experiments on dogs comparing 

 the recuperative effect after fasting of cooked meat, broth, 

 and raw meat showed that the latter food is the most 

 efficacious. — Study of the variations in the toxicity of the 

 contents of the small intestine : modifications of the blood : 

 MM. Charrin and Le Play.— The tectonic of the massif 

 of the Dent Blanche : Emile Argand — The geology of 

 Iferouane : R. Chudeau.

 Royal Society, December 6, 1905.— Mr. H. A. 

 Lenehan, president, in the chair.— A method of separ- 

 ating the clav and sand in clay soils and those rich 

 in organic matter : L. Cohen. — Latitude of the Sydney 

 Observatory ; appendix to a paper on the provisional 

 determination of astronomical refraction, from observ- 

 ations made with the meridian circle instrument of 

 the Sydney Observatory: C. J. Merfield. An alteration 

 in the accepted value (<£„= -33° 51' 4 I "-S5) is regarded as 

 unwise until the question is more completely discussed. — 

 Sociology of some Australian tribes : R. H. Mathews. 

 The author stated his opinion that among the social in- 

 stitutions of a primitive people there is none of greater 

 interest and value to the anthropologist than the study of 

 these social systems. He also expressed his conviction 

 that neither " sexual promiscuity " nor " group marriage " 

 has ever existed among the Australian aborigines. — An 

 undescribed species of Leptospermum and its essential oil : 

 R. T. Baker and H. G. Smith. " The lemon-scented 

 Leptospermum," the species described in this paper, 

 occurs in the north coast district of New South VVales 

 and the southern coast district of Queensland. It is a 

 shrub attaining a height from 6 feet to 12 feet, with erect 

 branches and small, lanceolate, ovate leaves, the flowers 

 occurring in the axils of the leaves on the upper branchlets. 

 The fruits measure about two to three lines in diameter. 

 Its differentiation from described species is based on both 

 morphological and chemical characters, although the former 

 are alone sufficiently marked to warrant its specific rank.
