nnn-linear terms of the ecjuations of movement are not 

 neglecie<l, by M. J. Boussmesq. — On the combination of 

 free nitrogen with the elements of carbon disulphide, by 

 M. Berthelol. (See Notes, p. 202.) — A new combination 

 6f argon, its synthesis and analysis, by M. Berthelot. (See 

 Notes, p. 202.) — rroiiaraliun ami pro[x'rties of pure fused 

 molybdenum, by M. Henri Muissan. I'urc fused molybdenum 

 has l>een obtained by means of the electric furnace. Its proper- 

 lies and reactions are vcr)' luUy given in the paper. Among 

 these it is stated to have a density = g'Ol, to be as malleable as 

 iron, and capable of being filed cold or forged hoi. When 

 heated in contact with carbon, it forms a steel by cementation 

 much harder than the pure metal. It is suggested that molyb- 

 denum may be used in the Bessemer process in place of man- 

 ganese, bccau.sc it furnishes a volatile o.\idc disengaged in the 

 gaseous state, and any excess of the. metal remaining in ihe iron 

 would lie as malleable as the iron it.self, and similarly capable of 

 l)eing hardened. — .Action of phenyl isocyanate on cam|)holic, 

 carboxylcanipholic, and phth.alic acids, by M. .\. Hallcr. — Dis- 

 cover)' of a third |>ernianent radiation of the solar atmosphere in 

 the gas from cleveite, by M. H. Deslandres. The line of wave- 

 length 706 '55 has been obtained in the spectrum of cleveite gas, 

 using a very luminous tul>e. This corresponds to a third per- 

 manent chromospheric line, leaving now only the green line 53 1 '66 

 — the coronal line not obtained from terrestrial sources. The 

 new line corresponds with a line observed in the argon spectrum 

 by the author, employing argon prepared by means of lithium. 

 It bears out the suggestion of Prof Kamsay, that argon and 

 cleveite gas contain a comnum constituent. — Comparative 

 observations with declinometers of different magnetic moments, 

 by M. Ch. Lagrange. — f)n the molecular transformations of 

 chromic hydrate, by .M. .-X. Kecoura. — On some basic halogen 

 compounds of the alkaline-earthy metals, by M. Tassilly — 

 Action of heat <m the double alkaline nitrites of metals of the 

 platinum group : Iridium compounds, by MM. A. Joly and K. 

 Leidic. Among the |)roducts of the action of heat on potassium 

 iridium nitrite, the author signalises the compnunds : 6IrOj. 

 KjtJ, and I2lr(),. K,0. — On the ammonium sodium acid tung- 

 slalcs, bv M. L. A. Hallopeau. The compounds 16WO.,. 

 3Na.,0.3('NH,);f).22ll.,0 and i2VVOj.4Na/J.(NH,),0.25M„0 

 are described —Rotator)' powers of some amyl derivatives in 

 the liquid and gaseous states, by M.M. I'h. .\. (luye and A. P. 

 do Amaral — On synthesi.sed colloids and coagulation, by M. J. 

 W. I'ickering. Synthetic colloids behave, when injected into the 

 vascular system, in a ver)' similar m.anner to the nucleo-alliumins. 

 — On a new bed of "cipolin" in (he rocks of the Central 

 Plateau, by .M. L. de Launay. — Gl.acial and fluvio-glacial deposits 

 of the basin of the Durance, by .\I.\I. \V. Kilian and A. Penck. 

 — Onthecoexi.slence,inthe iKisin of the Durance, of two systems 

 of conjiig.ate foUls of different age, by .M. Kmile Ilaug. — On the 

 Jurassic and Cretaceous systems in the Balearic Islands, by M. 

 II. Nolan.— On the Miocene of the Novalaise Valley, by MM. 

 J. Revil and II. Douxami. — Researches on the sugar and 

 glycogen in lymph, by M. A. Dastre. Lymph contains an ap- 

 preciable quantity (0'097 per thousand) of glycogen, obtainable 

 by the usual methmls. Olycogen is destroyed in lymph, in less 

 than twenty-four hours, by a diastasic ferment (lymphodiaslasc). 

 Rohmann has .shown the existence of a ferment of this kind in 

 lymph. The glycogen appears to be entirely carried by the 

 vjlid elements, and absent from the liquid plasma. The doctrine 

 that sugar is Ihe circulating form of carbohydrate is thus con- 

 firmed.— Modification of the heal radiated by the skin, under the 

 influence of continuous currents, by M. Ix;cerclc. — Denionslra- 

 lion, by a new pupillimicter, of the direct .action of light on the 

 iris, by M. Charles Henry. — Experimental production of 

 guMindised ganglionary lynqihadeiiouiia in a dog, by .M. Pierre 

 DelU'l. The author h.xs proved the infectious nature of this

Meteorological Society, May 7. — I'rof. Ilellmann, Presi- 

 dent, in the chair. Dr. II. Meyer spoke on most proK-ible

mean exhibit a relationship to each other w hich is dependent on 

 cloudiness, and shows diurnal and annual periodicities w hich arc 

 of considerable iinporlaiice for the characterising of clim.itc. The 

 same speaker next de.tll with the applicability of I^ambert's 

 formula to the calculaliim of the average direction of the wind. 

 He showed that later observers had neglected Lambert's pre- 

 .supposition thai either the velocity or pressure of the wind must 

 be introduced into his formula, and had employed the 

 "frequency"' instead, a fact which must lead to worthless 

 results. liut even when the formula is employe<i in accordance 

 with Lambert's instructions the resultant diiectiim arrived at htis 

 no climatic .significance. .\ lengthy discussion ensued, which the 

 President summed u]i as indicating that Lambert's fornnila was 

 not generally regarded as sufticiiig for Ihe calculation of the 

 average direction of the wind. tJnly in the case where the 

 movements of the air lie close together for a given pcrioil, and (K> 

 not differ by more than 2°, docs it appear at all profitable to 

 calculate the resultant by means of this formula.
