 even of the dark facial patch so prominent in that animal. 

 The new species was proposed to be called Budorcas 

 bedfordi, and female No. 2190 was selected as the type.

Paris. 



rt^-^^iny of Sciences, April 18,— M. Armsnd Gsulier in 

 the chair. — The president announced the death of Jean 

 Ikwsclia, corrcspondant in the section of physics. — Ph. 

 van Ti«Kham : The place of the Triuraceai in the class 

 of .Monocotyledons. The author is of opinion that this 

 order should be suppressed, reducing the class of the 

 Monocotyledons to two orders only. — Paul Sabattisr and 

 A. Maiihe : The catalytic esterification of the alcohols by 

 the fatty acids : the case of formic acid. Titanium oxide 

 is preferable to thorium oxide as a catalytic agent when 

 working at lower temperatures, such as are required when 

 formic acid is used. With this oxide the esterification 

 limit of 65 per cent, is reached at 150° C, an excess of 

 the alcohol being employed. — C. Bratu : The exponential 

 integral equation. — Maurice Fr^chet : The notion of the 

 differential. — M. d'Ocaarn* : .\ nomogram for the deter- 

 mination of the spaces described as a function of the time 

 whilst a ship passes from a velocity V, to velocity V,. — 

 H. Laroa* : The problem of the cable limited in two 

 directions. — M. Duaaaud : New uses for low voltage 

 bulbs. Sixteen lamps (10 volts, i ampere) are fixed on a 

 rotating disc in such a manner that each lamp receives 

 ao volts and 1-5 ampere during a fraction of a second. 

 With the expenditure of 30 watts a light apparently steady 

 is obtained equivalent to 10,000 candles, or the same 

 light as an arc consuming 6000 watts. — Guillaume 

 d* Pontonay : The photographic reproduction of docu- 

 ments by reflection. — L. Moreau and E. Vinet : The 

 elimination of lead arsenate from grapes in the process of 

 wine-making. — Em. Bourquelot and M. Bridel : The 

 action of invertin on the polysaccharides derived from levu- 

 kwe. — P. Sisley and Ch. Porcher : The elimination of 

 colouring matters from the animal organism. All the 

 observations lead to the conclusion that the microbial flora 

 takes part in the chemical processes of reduction of the 

 azoic colouring matters. — Hermann von Iheringr : The 

 history of the terrestrial fauna of the Brazilian forests. — 

 Armand Renter : The discovery in the Belgian West- 

 phalian of imprints of Calamostachys Ludwigi. — Francois 

 Favre : The relation between the partitions of Oppelia 

 Lias.
