Thus the motions of the planets do not 

 prove the truth of the Einstein theory, nor, 

 on the other hand, do they prove its falsity. 

 While these motions can be accounted for by 

 a certain distribution of matter in the solar 

 envelope, it has not yet been established by 

 observation that the matter is actually distrib- 

 uted through space in the required way. The 

 presence of the matter is unquestioned; its 

 distribution is still a problem of observational 

 astronomy. In the present state of our knowl- 

 edge regarding the distribution of this matter 

 throughout space, the motions of the planets 

 do not and can not furnish a definite answer 

 to the question as to the validity of the Ein- 

 stein hypotheses of relativity.

 Arsenated iensophenone and its derivatives: 

 W. Lee Lewis and H. C. Cheetham. Benzarsonie 

 acid is best prepared -by reduotiou of p-nitro- 

 benzoie and arsenation by means of Bart's reac- 

 tion. With phosphorus trichloride and pentachlo- 

 ride, dichloro-p-arsinobenzoyl-chloride results. By 

 means of the Friedel and Crafts reaction, benzo- 

 phenone-p-arsenious oxide, arsenious acid, and ar- 

 sonie aeid are formed. The similar derivatives of 

 4-methyl benzophenone-p-arsenious oxide, 4-me- 

 thoxy benzophenone-p-arsenious oxide, and 4-phen- 

 oxybenzophenone-p-arsenious oxide have been pre- 

 pared. Their nitro compounds, oximes, and iso- 

 mers are being studied. With arsanilic acid, di- 

 chloTO-p-arsinobenzoylchloride gives the di-arsen- 

 ated benzanilide. The further reactions of di- 

 ohloro-p-arsinobenzoylchloride with hydrocarbons, 

 ethers, phenols, and various amino- and hydroxy- 

 compounds are being studied. 



6 chlorophe^ialphanaptlmzarsine and some of its 

 derivatives: W. Lee Lewis and C. S. Hamilton. 

 6 chlorophenalphanapthazarsine is prepared by 

 heating phenyl alpha naphthylamine with arsenic 

 trichloride. 6 cholorophenalphanapthazarsine with 

 hydrogen peroxide gives phenalphanapthazarsinic 

 acid. The sodium salt of this acid haa been pre- 

 pared. A series of compounds, 6 methoxyphenal- 

 phanapthazarsine, 6 ethoxyphenalphanapthazarsine. 



6 propoxyphenalphanapthazarsine, 6 butoxyphen- 

 alphanapthazarsine, 6 phenoxyphenalphanaptha- 

 zarsine are prepared by treating 6 ohlorophenal- 

 phanapthazarsine dissolved in xylene with the cor- 

 responding sodium alcoholate. 6 bromophenal- 

 phanapthazarsine is prepared by refluxing 6 

 phenaJphanapthazarsine oxide or 6 phenoxyphenal- 

 phajiapthazarsine with hydrobromie acid. 6 

 phenalphanapthazarsine oxide is prepared from 

 6 chlorophenalphanapthazarsine by heating with 

 silver oxide. 



Condensation reactions mith ieneyl cyan/ide: 

 Feed W. Upson and T. J. Thompson. Several 

 phenyl aUcyl succinic nitrils have been made by 

 condensing benzyl cyanide either (1) with the 

 cyanhydrine of the aliphatic aldehyde in the 

 presence of sodium methylate, or (2) with the a 

 brom ester of the fatty acid in the presence of 

 sod-amide in ether suspension. Saponification of 

 the resulting condensation products has given sub- 

 stituted succinic acids. The following have been 

 made by method No. 2 : methyl phenyl succinic 

 acid, m.p. 185° ; ethyl phenyl succinic aeid, m.p. 

 194° ; N. propyl phenyl succinic acid, m.p. 214° ; 

 and the following have been made by both meth- 

 ods : Iso-propyl phenyl succinic acid, m.p. 178° ; 

 iso-butyl phenyl succinic acid, m.p. 186°. The 

 nitrils of the higher members can be saponified 

 only under pressure. Some evidence has been 



H 



obtained for the formula CjHj — C=C=N — Na for 



the sodium salt of benzyl cyanide. 



Derivatives of trihalogen tertiary -iutyl alcoTiols. 

 IV. The ienzoic acid ester of trihromo-tertiary 

 butyl alcohol or trometone liemoic acid ester: T. 

 B. Aldeich. The benzoyl ester of tribromo ter- 

 tiary-butyl alcohol, 0„Hi,CO . GO— CjHoBrs, is pre- 

 pared most conveniently by mixing molecular quan- 

 tities of benzoyl chloride and preferably anhydrous 

 tri-bromo tertiary butyl alcohol and heating on 

 the steam bath until hydrogen bromide ceases to 

 be given off. The ester is purified by heating on 

 the steam bath with 5-10 per cent, caustic soda 

 solution, washing with water, and finally recrys- 

 tallizing from alcohol. It crystallizes in the mono- 

 clinic system and melts at 89-90°. It is readily 

 soluble in the organic solvents^ but insoluble in 

 water. It is not so readily saponified as the ali- 

 phatic esters of either chloretone or bromotone. It 

 is practically non-volatile at either incubator or 

 room temperature, and is not volatile with steam 

 to any extent. In general its properties are the 

 same as the corresponding ester of trichloro-
