ENGLISH: The following report describes the findings of an "El Niño" project carried out at the Department of Meteorology of the University of California, Los Angeles, at the request of, and with funds provided from, the Inter-American Tropical Tuna Commission. The project was, in its early stages, supervised by Professor M. Neiburger, but was in June 1959 transferred to Professor J. Bjerknes, who thereby became the sole author of this final report. Readers who may be interested in the general background of knowledge of the maritime meteorology of the Eastern Pacific are herewith referred to Professor Neiburger's final report of the "Subtropical Pacific Meteorology Project." That report, submitted in September 1958 to the Office of Naval Research, summarizes the results of all the meteorological soundings released at sea since 1949 from California in the north to Peru in the south. The soundings off Ecuador and Peru were all taken by the "Shellback" expedition during July 1952. Important as this first exploration of the atmosphere over the Eastern Equatorial Pacific was, it did not even begin to explore " El Niño " itself, which is confined to the southern summer season and, moreover, only reaches catastrophic proportions in a few exceptional years. SPANISH: Este estudio da a conocer los resultados de una investigación que, bajo el nombre de Proyecto "El Niño", ha sido efectuada en el Departamento de Meteorología de la Universidad de California, Los Angeles, a solicitud de la Comisión Interamericana del Atún Tropical y con fondos provistos por ésta. En sus primeras etapas, el proyecto fué supervisado por el Profesor M. Neiburger, pero en junio de 1959 fué transferido al Profesor J. Bjerknes, quien de este modo vino a ser el solo autor de este informe final. A los lectores interesados en los conocimientos de fondo de la meteorología marítima del Pacífico Oriental se les recomienda consultar el informe final del Profesor Neiburger intitulado "Subtropical Pacific Meteorology Project". Este informe, sometido a la "Office of Naval Research" en septiembre de 1958 sumariza los resultados de todos los sondeos meteorológicos efectuados en el mar desde 1949 en el área entre California en el norte y Perú en el sur. Todos los sondeos frente al Ecuador y el Perú fueron hechos por la Expedición "Shellback" durante el mes de julio de 1952. Importante como fué esta primera exploración de la atmósfera sobre el Pacífico Ecuatorial del Este, ni siquiera comenzó a explorar "El Niño" en sí, que se confina a la estación de verano en el sur y, más aún, sólo alcanza proporciones catastróficas en unos pocos años excepcionales.

Megacyclops viridis Jurine, noticed in Lago Maggiore in 1912 by De Marchi from the littoral vegetation of Pallanza, is a normal member of the littoral plankton of the lake. The subgenus Megacyclops, created by Kiefer in his revision of the viridis-vernalis group, contains european and american species some of which are today considered as varieties of the species viridis. This paper examines morphology and of the distribution of the Italian viridis in Lake Maggiore.

By the industrial cultivation of blue-green algae, there very much appears the important question about their carbon nutrition. Spirulina grows within the range of pH value of medium of 8.5 - 11.0. In this range of pH value in the culture medium CO2 is present in the form of bicarbonate and carbonate, which serves as principal source of carbon for the present type of algae. There is little information yet about the influence of the pH of the medium, and the form of carbon components of the medium, on the rate-increase of Spirulina. Investigations were conducted into the influence of some pH values of medium on the rate-increase of the alga Spirulina platensis.

These minutes report on colloquium on the methodology of radiation measurement under water. The meeting was held on 3-5 January 1957, at the Biological Station, Lunz, Austria. The participants of the colloquium discussed various methodologies of radiation measurements, basic methods such as Secchi Disc and underwater photometer as well as specialist equipment like the absolute radiation apparatus.
