✦ Synopsis

In this paper, we have proved in theory that the sign of the current stiness matrix provides a correct indicator for determining the sign of the loading parameter in the arc-length algorithm before the ®rst bifurcation point is encountered, but may not be the case thereafter.

## Abstract Presently X‐ray crystallography of protein–antibody complexes is still the most direct way of identifying B‐cell epitopes. The objective of this study was to assess the potential of a computer‐based epitope mapping tool (EMT) using antigenic amino acid motifs as a fast alternative in a

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.
