✦ Synopsis

When NzO rerlcts with irradiated MgO, an ESR signal due to O-is found. rhis s+xies is highIy reactive ZU& v/h= mofetu& CW~=II, cubon monoxideand ckblen& sue ads&d at 77% an 0: new sign&s are fa~d due to tlgz fop mation of 0;. CD2 and CZH40-radicals.

Revious studies [f ,2] demonstrated that nitrous. oxide was dissociated into its elements when contacted with ultraviolet irradiated magnesium oxide. ESR spectroscopy has provided good evidence on the formation of O-species. Ten& et al. [l] have reported that this radical reacts readily with oxygen at 298°K to give a complex assigned to the ozonide ion O$. This paper presents evidence that O-is highly reactive even at low temperature and forms new species by reaction with 02, CO and ethylene.

Acute and Chronic Toxicity of Veratrum V

Acute and Chronic Toxicity of Veratrum Viride††The Veratrum viride studied was the whole-powdered drug marketed by Irwin, Neisler & Co. under the name, Vertavis. The work reported herein was supported by a grant from this firm. The batch of powder used in these experiments was stated by the manufacturer to have been assayed biologically by the Craw method on Daphnia magna. One Craw unit of the material studied was stated to be 15.6mg. With regard to this assay, Mr. R. O. Craw has been so kind as to allow us to publish a brief explanation: A reference lot of Yerolrum oirid; powder was set-aside as a standard and a 10% w/v aqueous extract was made of this powder. The average median length of life in 50 assays of 1000 daphnia on immersion in the solution was determined to be 2.22 hours. The daphnia were considered dead when the heart was found to be in systolic standstill on microscopic examination. Succeeding lots of powder were assayed and their potency determined by relating the median length of life of daphnia to 2.22 hours, which is one unit. Twenty assays of 10 animals each were used on each lot of powder.‡‡The authors wish to thank Dr. J. F. A.,McManus of the Department of Pathology for a pathologic report on the tissues, and Mr. James Thomas and Mrs. Bobby E. Teague for technical assistance.
