Fundamentals of the two-line method of emulsion calibration, in which the characteristic curve is derived from densities of two spectrum lines of constant relative intensity, photographed at different densitiy levels, are discussed. It has been found, that the principles of this method can be applied to the presentation of data obtained by any...

In a previous paper evidence was given that a step sector yields the same calibration curve for a photographic emulsion with either an intermittent light source or a continuous one, provided the emulsion has a negligible intermittency effect under the prevailing conditions. The data of that paper are now presented in a new way, based on that of...

The experiments of Havens, Ward, Drill and Paul, a Neefe and his associates4, 5,~,~ and:Paul, Havens, Sabin and Philip 9 on human volunteers make the virus etiology of infectious hepatitis at the least highly probable. The virus seems to be present in the blood, the feces and perhaps in the urine and the throat washings. As the human experiment...

Introduction. The way in which insoluble phosphates are absorbed by the plant is still a matter of some doubt. It is generally accepted that the carbonic acid, excreted by the plant roots, is capable of bringing insoluble phosphates into solution.

1. A conjugase activity (liberation of free folic acid from the conjugate) is not found in normal gastric juice at pH2 and 7. This confirms the results of Welch et al. They also found no free folic acid but they did not investigate whether the conjugate was changed by the enzymes. 2. In our experiments it is clearly shown that the vitamin B_c...
