with normal dry fruits, twist-nuts have a wrinkled appearance. These 

 nuts, he says, never germinate, the kernel being always dry, but not 

 thicker than the normal.

Table illustrating in the Case of Entada scandens the Method 

 OF Determining the Water and Solid Constituents in the Pre- 

 resting, Resting, and Swollen Stages for a Number of Seeds, 

 FOR which the Requisite Data are given on pages 200, 201 for 

 THE Shrinking and Swelling Regimes, and on pages 135 to 137 

 for the Water-contents of the Resting Seed. 



The data required, taking Entada scandens as an example, are the weight of the 

 resting seed (400 grains), the shrinking and swelling ratio (2 "5), the proportional weights 

 of coats and kernel in each of the three stages, and the water-contents of the coats and 

 kernel of the resting seed, as determined by exposure to a temperature of 100° C. 



The shrinking and swelling ratios are taken as the same, viz. 2-5, 

 since one is sometimes a little larger and sometimes a little smaller than 

 the other ; and it would be arbitrary to make a distinction, more 

 especially as all the other data are based on average results. 



All the materials above given are worked out from the data given 

 in the tables on pp. 135 and 202. Results for a considerable number 

 of other seeds can be obtained in the same manner by utilising the 

 data given in the table on p. 200 for determining the shrinking and
