Paris. 

 Academy of Sciences, November i6. — M. P. Appell in 

 the chair.— H. Deslandres : Observation of the total 

 eclipse of August 21, 1914, by the expedition from the 

 Meudon Observatory. The expedition organised by the 

 Observatory of Meudon made observations at Strom- 

 sund, in Sweden. Photographs were taken with two 

 spectrographs, a brief description of which is given 

 (see p. 373). — A. Chauveau : The question of the 

 diminished resistance of enfeebled organisms to the 

 destructive action of the tubercle bacillus. The author 

 has previously published the view that healthy sub- 

 jects, living in close contact with tuberculous patients, 

 are as liable to contract tuberculosis as enfeebled 

 subjects. They are all, strong and weak, equally 

 liable to receive and cultivate the specific germs of 

 the disease if these germs succeed in penetrating in 

 the living state by the two usual modes of infection 

 (respiratory or digestive). The author discusses from 

 the public health point of view the opposite view more 

 commonly held, and protests against erroneous inter- 

 pretations of his views. — Andr^ Blondel : The most 

 general enunciation of the laws of induction. Experi- 

 ments are described showing that the enunciation of 

 the laws of induction in some well-known text-books 

 is too general. — M. Courty : Observation of the 

 transit of Mercury made at the Observatory of Bor- 

 deaux, November 7, 19 14. — P. Gaubert : Artificial 

 macles of tin. — Marcel Baudouin : Discovery of a 

 menhir remaining upright under a dune on the coasts 

 of Vendee. The stone was found in modern 

 Quaternary deposits and was indisputably of human 

 workmanship.^Maurice Lugeon : The presence of 

 crystalline plates in the Prealps and their significa- 

 tion. — H. Colin : The saccharogen in the beetroot. — 

 P. Hariot : The marine flora of the island of Tatihou 

 and of Saint- Vaast-la-Hougue. 



Calcutta. 

 Asiatic Society of Bengal, November 4. — J. J. Kieffer : 



Chironomides du Lac de Tiberiade. Six new species 

 are described and one already known from Europe 

 and North Africa (Pelopia monilis) recorded from the 

 Lake of Tiberias. — H. Sastri : Recent additions to our 

 knowledge of the copper age antiquities of the Indian 

 Empire. The note brings up to date the information 

 about the copper or bronze antiquities of India by 

 noticing some fresh rnaterial that has come to light 

 since Mr. V. A. Smith wrote on the subject in the 

 Indian Antiquary, and makes some corrections in the 

 descriptions by Mr. Smith.
