✦ Synopsis

This study evaluates using factors extracted from the autocorrelation function (ACF) as cues for sound localization of the median plane. The amplitude of the transfer function for sound incident from the median plane to the ear entrances measured (see reference [6]) is translated into the ACF. It is shown that the sound localization in the median plane can be characterized by factors extracted from the ACF. These cues are the e!ective duration of the normalized ACF, C

, the delay time of the "rst peak , and its amplitude . 2001 Academic Press

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.
