experiments. — Ljevo-canipholic acid : Marcel Guerbet. A 

 good yield of this acid is obtained by heating /-borneol 

 with dehydrated caustic potash in sealed tubes. The acid 

 has a rotation au=— 49.1. — The alkaline reduction of 

 o-nitrodiphenylniethane : P. Carre. Reduction with zinc 

 dust and caustic soda gives o-hydrazodiphenylmethane and 

 o-aminodiphenylmcthanc. — The influence of aeration on the 

 formation of volatile products in alcoholic fermentation : 

 E. Kayser and A. Demolon. The amounts of aldehyde, 

 acids, and esters are all modified by access of air to 

 fermenting liquids. The presence of air, therefore, is 

 an essential condition for the production of bouquet 

 in wine. — The anatomy of the human thymus : Henri 

 Rieffel and Jacques Le Mee. The two lobes of this 

 gland are not united, but are easily separable, at least in 

 the case of newly born infants. The contact of the 

 thymus with the thyroid gland is not exceptional ; this 

 contact has been observed in 20 per cent, of the glands 

 examined. — The rudimentary organs of the larvae of the 

 Muscidre : J. Pantel. — Contribution to the study of the 

 singing voice : M. Marage. Curve tracings are given 

 showing the changes taking place in the transition stage 

 between chest and head notes. — The anion of ink on the 

 photographic plate : Guillaume de Fontenay. A criticism 

 of some experiments by M. Darget. — The treatment of 

 Baleri in the horse by orpiment : h. Thiroux and L. 

 Teppaz, It is now shown that there are three forms of 

 trypanosomiasis, curable by treatment with orpiment, in- 

 festing horses in Gambia, Souma, and Baleri. The 

 diseases caused by T. coiigolense and T. briicei still have 

 to be studied from this point of view. — Studies of cancer 

 in mice. The different types of tumours appearing in the 

 same growth : L. Cuenot and I.. Mercier. — .Xn enormous 

 urinary calculus in man : A. Guepin. This calculus was 

 removed from a man sixty-eight years of age, measured 

 8-5 cm. by 6-8 cm. by 4-5 cm., and weighed 220 grams. — 

 The source of the Bise at Thau : .MM. Chevallier and 

 Sudry.
