Variations in the products of inertia of the Earth are calculated from atmospheric pressure variations. Expressions for the variation of latitude are derived taking damping and possible resonance into account. It is found that, in general character, the variation of latitude is explainable on the assumption that the free motion is subject to random disturbances and that the forced motion is due to seasonal movement of air masses.

The increase of PO4 concentration in Dhar yeast culture does not influence its other physiological properties except its nitrogen losing and nitrogen fixing properties. The increase of PO4 in the culture first converts the nitrogen loss of Dhar Yeast cultures to nitrogen fixation. This nitrogen fixation then increases with the increase of PO4 in the culture within a certain limit, after which the increase of PO4 decreases the nitrogen fixation. On still further increase of PO4 in the culture this fixation again returns to loss of nitrogen which then increases with the increase of PO4 in the culture.

A higher concentration of potassium diminishes volatile acid and also yeast production beyond 0.2 gms. of potassium in Dhar Yeast (1) culture. The carbon usage during fermentation and the percentage carbon in cell is more at lower concentration which goes on falling with increasing concentration. At 0.1 gms. of potassium it is 51.9069 % and falls down to 31.8604 % at 0.5 gms. of potassium. The increase of potassium concentration also influences the nitrogen fixing property and nitrogen balance in Dhar Yeast cultures. Little amount of nitrogen is fixed at lower concentration which increases with incremental concentration of potassium within a certain limit, after which there is continuous decrease with further concentration. The nitrogen used during fermentation and percentage nitrogen in cell also follows the same pathway.
