All the viable microorganisms in the air have been transferred to the atmosphere either from the land or the sea. A comparison of the micro-flora of marine air with that of normal sea water and of land areas should indicate the major source of organisms in the atmosphere over the ocean
Corrections have to be applied to the readings of protected and unprotected reversing thermometers because they are read at a temp erature that differs from that at the time of reversal. In deriving these corrections it is generally assumed that Feruglio’s (1912) equa tion [(5) below] is exact. It is shown here that Feruglio’s equation is not quite exact, but a close approximation.

Statement of the Problem.—In a previous communication, Winsor and Walford (1936) analyzed the results of repeated vertical hauls of different types of plankton nets, making use of data available in the literature. They concluded that the observed rcsidts could be accounted for reasonably well on the assumptions that (a) the organisms were randomly distributed in the medium and (b) that t…
