a somewhat large minority the distal starch is the least 

 resistant and in these grains, there is always granulation 

 of the portion immediately surrounding the hilum, hut 

 not much fissuring or granule formation elsewhere, than 

 in N. sarniensis var. corusca major. There are fewer 

 grains in which dissolution of one point in the capsules 

 occurs than in N. sarniensis var. cprusca major. The 

 gelatinized grains are large and thin-walled and less dis- 

 torted than in N. sarniensis var. co-rusca major. 



The reaction with sodium hydroxide begins in a few 

 grains in half a minute. Complete gelatinization occurs 

 in less than 0.5 per cent of the entire number of grains 

 and total starch in 5 minutes; in less than 0.5 per cent 



01 the grains and 1 per cent of the total starch in 15 

 minutes; in less than 0.5 per cent of the grains and 



2 per cent of the total starch in 30 minutes; in about 

 0.5 per cent of the grains and 3 per cent of the total starch 

 in 45 minutes; in about 1 per cent of the grains and 

 4 per cent of the total starch in 60 minutes. (Chart 

 D 5242.) 



The reaction with sodium sulphide begins in rare 

 grains in 1 minute. Complete gelatinization occurs in 

 less than 0.5 per cent of the entire number of grains and 

 total starch in 5 minutes; in about 0.5 per cent of the 

 grains and '2 per cent of the total starch in 15 minutes ; 

 in about 1 per cent of the grains and 3 per cent of the 

 total starch in 30 minutes; slight advance in 45 minutes; 

 in about 2 per cent of the grains and 4 per cent of the 

 total starch in GO minutes. (Chart D 243.) 



The reaction with sodium salicylate begins imme- 

 diately. Complete gelatinizatiou occurs in about 78 per 

 cent of the entire number of grains and 91 per cent of 

 the total starch in 5 minutes; in 100 per cent of the 

 grains and total starch in 10 minutes. (Chart D 244.) 



The hilum becomes as distinct as in N. sarniensis 

 var. corusca major, but the lamella? are less distinct than 

 in those grains. A narrow refractive band, which is not 

 so narrow but more refractive than in N. sarniensis var. 

 corusca major, is formed about the margins of the 

 grains. Gelatinization begins usually first at the proxi- 

 mal end and then at the distal end, differing in this 

 from N. sarniensis var. corusca major in which gelatiuiza- 

 tion usually does not begin at the distal end immediately 

 following the gelatinizatiou of the proximal end. Gela- 

 tinization is rather different from that in N. sarniensis 

 var. corus~ca major, and progresses smoothly from the 

 proximal end and from the distal end by serial separation 

 and gelatinization of the lamella?, and continues so 

 until the most resistant part of the grain midway be- 

 tween the hilum and the distal end is reached, then 

 the margin on either side is first rapidly gelatinized, then 

 the central portion, accompanied by considerable infold- 

 ing and invagination of the capsule at the proximal and 

 distal ends. The gelatinized grains are large and more 

 distorted than in N. sarniensis var. corusca major. 



The reaction with calcium nitrate begins in rare 

 grains in 1 minute. Complete gelatinizatiou occurs in 

 less than 0.5 per cent of the entire number of grains and 

 total starch in 5 minutes; in less than 0.5 per cent of 

 the grains and 1 per cent of the total starch in 15 min- 

 utes ; in about 0.5 per cent of the grains and 2 per cent 

 of the total starch in 30 minutes ; in about the same per- 

 centage of the grains and 4 per cent of the total starch in 



45 minutes; little U' any further advance in 00 minutrs.

The reaction with uranium nitrate begins in a few 

 grains in 1 minute. Complete gelatinizatiou occurs in 

 about 0.5 per cent of the entire number of grains and 1 

 per cent of the total starch in 5 minutes ; in about 1 per 

 cent of the grains and 2 per cent of the total starch in 

 15 minutes; slight advance in 30 minutes; in about the 

 same percentage of the grains and 3 per cent of the total 

 starch in 45 minutes ; in about 2 per cent of the grains 

 and 5 per cent of the total starch in GO minutes. (Chart 

 D24C.) 



The reaction with strontium nitrate begins in a few 

 grains immediately. Complete gelatiuizatiou occurs in 

 about 2 per cent of the entire number of grains and 

 12 per cent of the total starch in 5 minutes; in about 3G 

 per cent of the grains and 78 per cent of the total starch 

 in 15 minutes; in about 57 per cent of the grains and 

 86 per cent of the total starch in 30 minutes; in about 

 75 per cent of the grains and 93 per cent of the total 

 starch in 45 minutes; in about 84 per cent of the grains 

 and 97 per cent of the total starch in GO minutes. (Chart 

 D247.) 



The reaction with cobalt nitrate begins in a few 

 grains in 1 minute. Complete gelatinization occurs in 

 less than 0.5 per cent of the entire number of grains and 

 total starch in 5 minutes; in about 0.5 per cent of the 

 grains and 1 per cent of the total starch in 15 minutes; 

 in about 1 per cent of the grains and 2 per cent of the 

 total starch in 30 minutes; little if any further advance 

 in 45 and 60 minutes. (Chart D 248.)

 utes; in about 0.5 per cent of the grains and 2 per

 grains in 2 minutes. Complete gelatinization occurs in 

 less than 0.5 per cent of the entire number of grains and 

 total starch in 5 minutes; in about 0.5 per cent of the
