first instant, in sea-water, and Vt is volume at time t), plotted against the time in 

 50 per cent, sea-water. K, the velocity constant, is obtained from the slope of 

 the lines. 



HCN for any given length, the greater is the rate of swelling. 

 Fig. 5 shows the rate at which the velocity constants increase 

 with increase of concentration and increase in time of exposure to 

 the HCN solutions. Fig. 6 is a composite curve in which all the

velocity constants have been plotted to form a single curve. The 

 various velocity constants have been plotted against their re- 

 spective concentrations. The figure shows that the increase in 

 the rates of reaction proceeds at a regular rate whatever the con- 

 centration of HCN and length of exposure.
