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.

Committee reports. Report on patent law
Committee reports. Report on patent law revision**The evidence in support of the Preambles and Resolutions and suggested additions to the copyright, patent and trade-mark laws contained in the first part of our report was not published in the May Journal owing to want of space. I am now sending you the remaining part of the report, by request, as it is considered quite necessary for the members of the Association to have in their hands before the next annual meeting, the entire document for consideration and study. It is believed that this will decidedly facilitate matters and save much time at the annual meeting which otherwise might be used up in unnecessary discussion of the subject.Your Committee wishes to again emphasize that fact that we have no desire to impose our personal views on the Association. The copyright and patent laws were designed to promote progress in science and the useful arts and the trade-mark laws to protect the public from fraud and imposition. It is generally conceded that the laws as now interpreted and applied fall short in accomplishing their purpose. It is therefore incumbent upon the A. Ph. A., representing the pharmacists of America, to suggest proper modifications of the law, of such kind as to secure the very important objects for which they were enacted.β€”F. E. Stewarcth, Chairman.
