Os autores descrevem um aparelho destinado à medida contínua da água absorvida pela TFSA em condições de laboratório. O sorbímetro, cujo funcionamento obedece ao princípio dos vasos comunicantes, consta de um tubo em U cujos ramos verticais se ligam respectivamente à uma coluna de terra e à uma bureta de 100 ml. A bureta restabelece no tubo, a água absorvida pela terra. As leituras de bureta substituem as pesagens do método gravimétrico. O aparelho é recomendado para medidas a intervalos de tempo para os quais, o método usual é ineficiente. | This paper describes an apparatus designed to carry on the continuous measurement of the water absorption by soils under laboratory conditions. The apparatus was called "sorbímetro". The principle accordingly to the "sorbimetro" works is the same which governs the flow of water in the usual linked flasks. The apparatus has a U tube whose vertical arms are connected respectivelly, to a soil colunn and to a 100 ml burete; the burete keeps constant the volume of water in the U tube since the liquid is being absorbed by the soil. In the present method the readings on the burete substitute for the usual weighings. The method is recommended for measurements in time intervals in which the gravimetric method does not work too well.

22 páginas, 4 figuras, 3 tablas | [EN] Several hypothesis have been proposed to explain the heavy reduction in the sardine fisheries in NW Spain; its atribution to over-fishing should be rejected. As a matter of fact, sardine is fished only near or in the Rías, and the fluctuatins of the populations in the exterior and their availability in the Rías should be dealt with sperately. [...] | [ES] En años "anormales", alrededor del 70 por ciento de la sardina desembarcada en los puertos españoles correspondía a las costas atlánticas, y el 30 por ciento restante, a las mediterráneas. Sin embargo, a partir del año 1948, del 40 al 50 por ciento de las descargas se han venido haciendo en los puertos mediterráneos. Galicia ha figurado tradicionalmente a la cabeza de las pesquerías de sardina en el Atlántico, siendo Vigo el puerto pesquero más netamente sardinero, lo que dio lugar al desarrollo de importantes industrias derivadas, especialmente de conservas y salazones.
