Abstract
AN editorial note in the first issue for 1942 of Ciencia: Revista hispano-americano de Ciencias puras y aplicadas (published in Mexico) expresses the hope that its publication, interrupted for a time, will be regular and punctual in the future. Issues for the first half of 1942 deal with a great variety of subjects, some of cultural interest, others of a practical and technical character, and in addition, it contains short items of scientific importance from a great number of countries. Of special interest is a series of articles (not yet completed) by Prof. B. Cabrera, of the National University of Mexico, entitled “El Atomismoy Su Evolucion”, which provide an excellent account of the developments in our knowledge of atomic physics from the days of Democritus and Leucippus up to modern times. Dr. Honorato Castro contributes an article on the determination of the distance between two points on the earth's surface with sufficient accuracy to serve the needs of aviators. A spherical earth is assumed in the first case, and then it is shown how corrections can be applied when an ellipsoidal earth is considered. Biological and medical subjects are prominent, and among the latter may be noticed an important article by Dr. S. Obrador Alcalde, with the title, “Mecanismos Neurales De Los Ritmos Electricos De La Corteza Cerebral”. The author, who is connected with the Laboratory of Medical and Biological Research, School of Medicine and Institute of Neuro-Psychiatry, Mexico, deals with investigations. These few references will suffice to show the scope of the journal, and it may also be mentioned that a considerable amount of space is devoted to reviews of scientific works.
