Photometric Methods in Quantitative Autoradiography,n of the density of silver grains above various structures or under varying conditions, or the determination of absolute quantities of radioactivity. In both these cases, photometric measurement serves for more rapid and more exact evaluation of grain densities than would be possible by visual counting of the grains.

Botanical Applications of Microautoradiography,ysiological problems in the plant sciences was slow. There may be several reasons for this, the most pertinent of which is the different nature of plant cells and animal cells. Although the microautoradiographic technique is applicable in principle to both plant and animal tissues, plant cells with

Microautoradiography of Water-Soluble Organic Compounds,lecules occurring in plant cells are composed mainly of H, C, N, O, P, and S. From nitrogen and oxygen no radioactive isotopes with sufficiently long half-life are available for use as tracers. .PO. = and .SO.=, when occurring as monoesters, can be precipitated as lead and barium salts respectively,
