Abstract

The predictive equations of numerical forecasting are cast in differential form and do not have simple analytic solutions. In practice, the finite‐difference analogues of the differential equations are solved using a grid and the grid length has been chosen so that significant features of the synoptic chart are reasonably defined by values at the grid points of contour height or pressure. The purpose of this note is to enquire into the grid lengths that should be chosen so as to make the best estimate of the derivatives which appear in the equations.

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.

Report of Committee on National Legislat

Report of Committee on National Legislation,* American Pharmaceutical Association*This report was received and the report and resolutions were adopted. C. L. Eddy said that attention should be called to the growing tendency in the United States toward a bureaucratic form of government. Mr. Eddy referred to a law in New York state of this order which was abolished through the cooperative efforts of pharmacists and physicians. He also referred to a statement made recently in Congress-that "one in fifteen people is an employee of the Government; and these people who hold their jobs are making laws for our damnation.

Accepted dental remedies (1939). Secreta

Accepted dental remedies (1939). Secretary Harold L. Hansen, Council on Dental Therapeutics, states that this edition is similar to those which have geen prepared in the past under the direction of Dr. Sammuel M. Gordon, 1930–1938. (For the 1938 report see page 1284, Journal A. Ph. A.) the number of articles listed and described in this volume is considerably larger than in previous editions. Acceptance of a remedy is not an endorsement; the duration varies as to time and may be reconsidered; dentifrices are listed for one year; the rules have been adopted primarily with the object of protecting the dental profession and the public against fraud or imposition, undesirable secrecy and objectionable advertising
