Abstract The sedimentation differential agglutination technic is a modification of the Ashby method by means of which the concentration of immunologically distinct erythrocytes in a mixture can be determined by observing their volume after agglutination and subsequent sedimentation. The method has been applied to the determination of the efficiency of replacement transfusions, the survival of red cells after blood transfusion, and has afforded a method for the determination of production of erythrocytes under certain conditions. The results indicate an almost complete inhibition of erythropoiesis and the frequent presence of excessively rapid hemolysis in "blast" leukemias. In a number of instances in which simultaneous measurements by the sedimentation differential agglutination and radioactive phosphorus technics were made, good correspondence between the two methods was observed.

Quantitative Account

The phosphorus-containing constituents of various tissues of the rat were separated into five fractions. These were: inorganic and organic phosphorus soluble in aqueous 10% trichloroacetic acid; phosphorus soluble in 3:1 alcohol–ether; phosphorus derived from ribonucleic acid; and phosphorus derived from thymonucleic acid. In order to test the methods, inorganic phosphate, disodium phenyl phosphate, and purified ribonucleic and thymonucleic acids were added to a homogenate of rat liver in 10% trichloroacetic acid. It was possible by separation and analysis of the fractions to obtain a quantitative recovery of the added phosphorus in the appropriate fractions. The extent to which radioactive inorganic phosphate entered the other fractions was measured following its addition to a homogenate of rat liver in 10% trichloroacetic acid. When the fractionation was performed at room temperature it was found that all of the fractions except the organic acid-soluble phosphorus fraction contained negligible amounts of the added radioactive phosphorus. The amount of radioactive phosphorus taken up by this fraction could be reduced to a negligible quantity by working quickly and with cold solutions.Data are given showing the radioactive and nonradioactive phosphorus contents of the various fractions of liver, spleen, kidney, muscle, thymus gland, lymph node, prostate gland, and testis of the rat 24 hr. after the intraperitoneal injection of a solution of radioactive inorganic phosphate. By analysis of the urine, feces, and remainder of the rat after removal of the above tissues, a quantitative account was made of the injected radioactive phosphate.

1. A method for the determination of turnover time and turnover rate of plasma phospholipid is presented. 2. During the postabsorptive state 5.2 to 8.0 mg. of phospholipid phosphorus are turned over per hour in the plasma of dogs weighing 6–9 kilos. 3. The amount of phospholipid in an organ that is supplied by plasma phospholipid per hour is calculated.

The Galaxy

It is now possible to determine proper motions of high-velocity objects in such a way as to obtain with some accuracy the velocity vector relevant to the Sun. If a potential field of the Galaxy is assumed, one can compute an actual orbit. A determination of the velocity of the globular clusterωCentauri has recently been completed at Greenwich, and it is found that the orbit is strongly retrograde in the Galaxy. Similar calculations may be made, though with less certainty, in the case of RR Lyrae variable stars.
