[November 14, 1907 



mental study of the change in the absorption spectrum of 

 bromine vapour under pressures varying from one to 

 twenty atmospheres. — A new element, lutecium, resulting 

 from the splitting of Marignac's ytterbium : G. Urbain. 

 The separation was effected by fractional crystallisation of 

 the nitrates from nitric acid of density 1-3. The 

 characteristic lines in the arc spectrum of the new element 

 are given. For the purified ytterbium resulting from the 

 separation the name of neo-ytterbium is proposed. — Bi- 

 secondary butylene chloro#)'drin : K. Krassousky. An 

 account of this compound, recently described as new by 

 M. Louis Henry, was published by the author in 1902. 

 Further details of its preparation and properties are given. 

 — The alkaline granite massif of Dahomey : Henry 

 Hubert. — The uralitisation of pyroxene : Louis Duparc. 

 — Remarks on the structure of the aleurone grains in the 

 Graminaceae : .■\. Guilliermond. The author modifies 

 some conclusions drawn by him in previous publications. 

 The aleurone grains in the Graininaceas offer analogous 

 characters to those of the lupin. They are distinguished 

 only by their smaller content of protein (the latter con- 

 stituting only a thin layer round the globoids), by the 

 smaller number and larger size of the globoids, and by 

 the Insolubility of the protein in potash after fixation by 

 Ladowsky's method or by alcohol. — The experimental pro- 

 duclion of grapes without pips : Lucien Daniel. The 

 production of ripe grapes without pips can be caused by 

 vigorous pruning immediately after the fruit is set, and 

 is produced bv overfeeding at the time when the fertilised 

 seed starts developing with great activity. — The evolution 

 of Frenzelina. intestinal parasites of decapod Crustacea : 

 L. L6e:er and O. Duboscq. — Classification of the Zygo- 

 pteridca? according to the characters of their leaf 

 impression : Paul Bertrand. — Variations of density and 

 amount of oxygen of pools of sea water : R. Legendre. 

 — Observation of a discontinuous lightning flash : M. 

 Luizet.
