closely those of G. moorei than of C. zeylanicum, but in 

 60 minutes there is a greater variation of the amount 

 of gelatinization of the different grains than in C. zey- 

 lanicum. At the end of this period a larger proportion 

 of grains is completely gelatinized and the remainder is 

 less affected by the reagent than in C. zeylanicum. The 

 gelatinized grains are considerably less distorted and 

 more frequently contain some refractive granules than in 

 C. moorei, but they are somewhat more distorted and 

 contain less granules than in G. zeylanicum. The reac- 

 tions much more closely follow those of G. zeylanicum 

 than G. moorei. 



The reaction with potassium sulphide begins in very 

 few grains in 1 minute. Complete gelatinization occurs 

 in less than 1 per cent of the entire number of grains 

 (only the smaller grains) and less than 1 per cent of the 

 total starch in 5 minutes; in less than 1 per cent of the 

 grains and 1 per cent of the total starch in 30 minutes, 

 with little if any further progress at the end of 60 min- 

 utes. ( Chart D 136.) 



The enlarged refractive fissure at the hilum is much 

 more frequently seen than in G. moorei, but somewhat less 

 so and the gas more quickly collects in bubbles followed 

 by expulsion, and there is a more rapid loss of refrac- 

 tivity than in G. zeylanicum. The lamella? do not become 

 bo sharply differentiated as in G. moorei, but about the 

 same as in C. zeylanicum. Gelatinization begins and 

 proceeds as in the parents. The grains are disorganized 

 with the appearance of more refractive granules than in 

 G. moorei, but about the same as in G. zeylanicum with 

 the exception that in comparison with the latter the bril- 

 liant, scattered granules in the mesial portion are less 

 frequently observed. The gelatinized grains are swollen 

 and but little distorted, and they are less distorted and 

 more frequently retain a band at the proximal end and 

 sides, as well as a few scattered refractive granules, than 

 in G. moorei. They are a little more distorted at the 

 distal margin, and the band at the proximal end is 

 usually narrower with fewer refractive granules remain- 

 ing than in C. zeylanicum. The gelatinized grains bear 

 some resemblance to the untreated grain, much more 

 than in C. moorei but slightly less than in C. zeylanicum. 

 The reactions exhibit a much closer relationship to C. 

 zeylanicum than C. moorei. 



The reaction with sodium hydroxide begins in rare 

 grains in 1 minute. Complete gelatinization occurs in 

 about 1 per cent of the entire number of grains and 2 

 per cent of the total starch in 5 minutes ; in about 2 per 

 cent of the grains and 5 per cent of the total starch in 

 15 minutes ; in about 3 per cent of the grains and 6 per 

 cent of the total starch in 30 minutes; in about 5 per 

 cent of the grains and 7 per cent of the total starch in 45 

 minutes ; and in about the same percentage of grains and 

 8 per cent of total starch in 60 minutes. (Chart D 137.) 



The reaction with sodium sulphide begins in a few 

 grains in 1 minute. Complete gelatinization occurs in 

 about 2 per cent of the entire number of grains and 3.5 

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

 cent of the grains and 6 per cent of the total starch in 

 15 minutes ; in about 5 per cent of the grains and 9 per 

 cent of the total starch in 30 minutes; in about 7 per 

 cent of the grains and 9.5 per cent of the total starch in 

 45 minutes ; and in about 8 per cent of the grains and 15 

 per cent of the total starch in 60 minutes. (Chart D 138.) 



A bubble is less frequently detected at the hilum than 

 in either parent, and when present it is much more often 

 inclosed within an enlarged fissure than in C. moorei, 

 but less frequently than in C. zeylanicum. A few la- 

 mella? are more sharply defined, but the definition is soon 

 lost and not so distinct over nearly so much of the grain 

 as in G. moorei, but about the same as in 0. zeylanicum. 

 A refractive border is more sharply differentiated from 

 the main body of the grain than in C. moorei, but it is 

 slightly less prominent than in C. zeylanicum. Fissures 

 appear which are of the same character as those of the 

 parents, but they are deeper and much more profusely 

 branched than in C. moorei; yet not so deep and have a 

 character of branching much like that in C. zeylanicum. 

 The mesial portion of the grain is disorganized with the 

 appearance of from slightly to very refractive granules, 

 the mean degree of refractivity is much higher than in 

 G. moorei, but somewhat less than in G. zeylanicum. 

 The distal margin is more frequently the first region to 

 become gelatinized than in either parent; there is more 

 distention of the capsule at this end with a less number 

 of convolutions, and the reaction proceeds farther from 

 this end before much progress occurs around the hilum 

 than in either of the parents. The border at the distal 

 margin is broken down without the appearance of gran- 

 ules, as in the parents. A narrow refractive border at 

 the proximal end and sides is more resistant than in the 

 parents, and it becomes profusely striated and may dis- 

 organize into linear granules, the latter not being ob- 

 served in C. moorei, but being the same as in C. 

 zeylanicum. 



The completely gelatinized grains are much swollen 

 and often much distorted at the distal margin, 

 the mean distortion being considerably less than in C. 

 moorei but somewhat more than in C. zeylanicum. Grains 

 are often completely gelatinized with the exception of 

 a narrow refractive border at the proximal end and sides 

 nearby, which border may be profusely striated or broken 

 down into linear very refractive granules, together with 

 a group of refractive granules in an area around the 

 hilum, the border usually being broader and the granu- 

 lation more frequent than in G. zeylanicum, the resem- 

 blances being more marked to this species than to C. 

 moorei. The reactions exhibit a much closer relationship 

 to C. zeylanicum than to C. moorei. 



The reaction with sodium salicylate begins in a few 

 grains in 1 minute. Complete gelatinization occurs in 

 about 5 per cent of the entire number of grains and 8 

 per cent of the total starch in 5 minutes; in about 20 

 per cent of the entire number of grains and 26 per cent 

 of the total starch in 15 minutes; in about 80 per cent 

 of the grains and 87 per cent of the total starch in 30 

 minutes; in about 97 per cent of the grains and over 98 

 per cent of the total starch in 45 minutes ; and in all of 

 the starch, excepting small parts of few grains, making 

 over 99 per cent of the total starch gelatinized, in 60 

 minutes. (Chart D 139.) 



A bubble appears at the hilum and is inclosed within 

 an enlarged fissure in the majority of grains; decidedly 

 more frequently than in C. moorei, but somewhat less 

 often than in G. zeylanicum. The bubble which appears 

 within the hilum expands much more than in C. moorei, 

 but less than in C. zeylanicum. The definition of the 

 lamella? and the formation of a refractive border less
