With non-metals, such as sulphur, phosphorus and 

 iodine, no action was observed. 



Ammonolysis of Certain Sydrazine Salts: A. E. 



HOULEHAN. 



The behavior toward liquid ammonia of several 

 hydrazine salts has been studied in a specially 

 designed extraction apparatus. It was found that 

 the monosulphate, disulphate, dioxalate and di- 

 selenate of hydrazine readily ammonolyzed, yield- 

 ing the corresponding ammonium salt and free 

 hydrazine, but that the monophosphate and the 

 diphosphate did not ammonolyze. 



Aluminum Anodes in a Liquid Ammonia Solution 

 of Ammonium Trinitride: M. J. Brown and 

 G. W. Pawel. 



Aluminum anodes were corroded in a liquid am- 

 monia solution of ammonium trinitride, with for- 

 mation of a grayish scale. This substance was 

 filtered and was washed with pure liquid ammonia 

 in an apparatus designed to exclude all moist air, 

 and to permit the proper sampling of the product. 

 The purified substance, when brought into contact 

 with water, became red hot and decomposed, yield- 

 ing aluminum hydroxide, ammonia, hydronitrio 

 acid, nitrogen and hydrogen. Repeated analysis 

 has shown it to consist, in all probability, of a 

 partially ammoniated aluminum nitride mixed 

 with a small percentage of an ammonobasic 

 aluminum trinitride. This is considered to have 

 been formed by an initial ' ' nitrination ' ' of the 

 metallic aluminum by the discharged nitrine ions, 

 and subsequent ammonolysis of the aluminum tri- 

 nitride formed. An accurate gasometric method 

 for the determination of small amounts of hydro- 

 nitric acid has been devised during the course of 

 the research. 



Oxidation of Arsenious and Antimonious Oxides 



by Means of Air and Water: J. Bishop Tingle 



and VoLNEY A. Ray. 



It is well known that arsenious and antimonious 

 oxides (AsjOo and SbjOs) are transformed easily, 

 hj many oxidizing agents, into arsenic and anti- 

 monic oxides (AsjOs and SbjOc), but the authors 

 lave failed to find any record of the fact that this 

 change can be brought about by the action of air 

 and water. 



The observations on which this conclusion is 

 based were made in the course of some experiments 

 having for their object the preparation of certain 

 organic derivatives of arsenious and antimonious 



The organic compound was mixed with a little 

 alcohol and water, the respective oxide added and 



the mixture boiled in a test-tube which was fitted 

 to a reflux condenser of small bore. 



After about sixteen hours the liquid still had 

 an odor of alcohol, but the oxides were found to 

 have been converted into the antimonic and ar- 

 senic stages of oxidation. 



Similar results were obtained by the use of the 

 oxides, water and alcohol (99 per cent.) only, in 

 the ratio 0.5 g., 5 c.c. and 3 e.c, respectively, but 

 the boiling was continued during about 26 hours, 

 at the end of which time the change was prac- 

 tically quantitative.

 Ozone: gAERY N. Holmes. 



The author of the paper reviewed the present 

 technical uses of ozone such as water purification, 

 ventilation by oxidation of ' ' air sewage, ' ' bleach- 

 ing, deodorizing, aid to cold storage, sterilization, 

 organic synthesis and others. The cost of ozone 

 as made by different methods was discussed. 



The various methods of making this gas in the 

 laboratory were enumerated and the author con-
