Action of high temperatures upon antimony peroxide, by M. H. 
Baubigny. At a temperature just above the melting-point of 
gold, antimony peroxide is almost completely decomposed into 
oxygen and the volatile antimony trioxide.—Action of tannin 
and some other aromatic derivatives upon some alkaloids and 
compound ureas, by M. C&chsner de Coninck.—On some 
derivatives of anethol, by M. Georges Darzens. The un- 
saturated nature of anethol was shown by the formation of a 
chlorine derivative by addition, The chlorine was used in 
carbon tetrachloride solution, a very convenient form of using 
chlorine in known amounts. This derivative cannot be dis- 
tilled, as it readily splits off hydrogen chloride, leaving a mono- 
chloranethol from which, by addition of chlorine and bromine 
in carbon tetrachloride solution, the corresponding saturated 
halogen compounds were prepared.—On the combination of 
iodine with rice and wheat starch, by M. G. Rouvier.—On the 
solubility of the red colouring matter of the raisin, and 
on the sterilisation of the expressed juice of fruit, by M. 
A. Rosenstiehl.—On the Japanese and Chinese vines 
acclimatised at Damigny (Ome), and on the composition 
of the wines which they produce, by M. L. Lindet.-—On 
the composition of the ancient Indian pottery of Vene- 
zuela, by M. F. Geay.—Refractory period in the nervous 
centres, nervous wave, and consequences which result, from 
the point of view of cerebral dynamics, by MM. André Broca 
and Charles Richet.—On a new anatomical apparatus observed 
in the peritoneum, by M. J. J. Andeer.—On some anatomical 
peculiarities observed in the larva of Thriaxion Halidayanum, 
by M. J. Pantel.—On the relations of Antennophorus Uhimanni 
(Haller) with Zaszus méxtus (Nyl), by M. Charles Janet. The 
Antennophorus are parasites living on the Laszus, and are 
nourished by a nutritive fluid exuded by the ants. The para- 
sites always place themselves symmetrically about the body of 
their host, so that his. movements are impeded as little as 
possible. —On some points in the geology of the environs of 
Bourganeuf (Creuse), by M. Ph. Glangeaud.—On the use of 
formaline in the preparation of microscopic specimens, after 
hardening with osmic acid, by M. Ch. Rousselet.—Synthesis of 
the elementary forces, by M. Bridou.
