HO— C : (COOC,H,), 



A benzene solution of this product gives a white 

 crystalline precipitate with dry hydrogen chloride, 

 probably an amidine salt. 



Dipropyl amine, on the other hand, adds to ethyl 

 cyantartraonate in molecular proportions, giving 

 likewise a white crystalline substance. It is less 

 stable than the benzyl amine compound, and gives 

 a similar crystalline product with dry hydrogen 

 chloride. The analysis corresponds to the follow- 

 ing formula: 



HO— C : (GOOCA), 



I 

 HN = C — N : (CjH,), 



The study of these and similar reactions is 

 being continued. 

 Arsenic and Antimony Derivatives of Certain 



Organic Acids: J. Bishop Tingle and K. A. 



Clabk. 



Ihe authors have prepared a number of new 

 arsenic and antimony derivatives of succinic acid. 



Similar experiments with camphoroxalic acid 

 and with some of its more complex amino deriva- 

 tives failed to give positive results. 



Phthalphenylamidic acid (phthalanilic acid), 

 under the conditions employed, was converted into 

 the anil. 



The experiments were made in an atmosphere 

 of carbon dioxide, in order to avoid oxidation of 

 the arsenious and antimonious oxides. Eeferenee 

 to this is made in another paper, which is pre- 

 sented before the inorganic section of this society. 



Professor Abel has examined the therapeutic 

 action of the new compounds mentioned above.

 The Action of Substituted Sydraeines on Beta-

Cecil Boord. 



Beta-orthotoluquinone and its condensation 

 products with unsymmetrical benzoylphenylhydra- 

 zine and unsymmetrical p-tolylhydrazine are de- 

 scribed. The two latter products upon saponifica- 

 tion yield benzeneazometacresol (CH3:OH:]Sr2^ 

 1:3:4) and p-tolylazometacresol (CH3:OH:N2 = 

 1:3:4), respectively. A study of these derivatives 

 is being made to determine the nature of ortho- 

 hydroxyazo compounds.

Finger and Zeh have described the compound 

 formed by the action of methyl or ethyl anthranil- 

 ate or cyanimido ethyl ether as o-carbethoxy 

 phenylcyanamide. It is now shown that the sub- 

 stance actually formed is ethyl benzoylenisourea, 



CbH,; 



^CO— NH., 



iCOCjH.5, 



and not a substituted cyanamide at all. Inci- 

 dentally carbethoxy and carbmethoxy phenyl- 

 cyanamide were made by a method, which leaves 

 no doubt as to their constitution, and found to 

 possess the properties customarily observed in 

 mono-substituted cyanamides and not at all those 

 of the compound described by Finger and" Zeh.
