ter. In the qualitative reactions with chloral hydrate, 

 nitric acid, potassium iodide, potassium sulphide, and 

 sodium salieylate many differences are noted, some rather 

 striking but mostly seemingly of minor importance. 

 The starch of the hybrid N. dainty maid in comparison 

 with the starches of the parents contains more aggre- 

 gates than that of N. elegans and as many as in N. crispa; 

 the irregularities are more numerous than in N. elegans 

 and about the same as in the other parent ; and while most 

 of the grains in relative sizes of the proximal and distal 

 ends resemble those of N. en-spa, there are more that 

 have the proximal end smaller than the distal end. The 

 hilum in distinctness is closer to N. crispa, while in the 

 absence of fissuration it is closer to N. elegans; in eccen- 

 tricity it also is closer to the latter. The lamella? are 

 finer than those of either parent, but nearer N. elegans, 

 while in general characters and arrangements they are 

 nearer N. crispa; the number is less than in either 

 parent, but nearer that of N. crispa. The size is some- 

 what closer to N. elegans. In the polarization, selenite, 

 and qualitative reactions the resemblances lean to one 

 or the other parent, but on the whole distinctly more to 

 2V. elegans. In the qualitative reactions with chloral 

 hydrate, nitric acid, potassium iodide, potassium sulpho- 

 cyanate, potassium sulphide, and sodium salieylate cer- 

 tain of the phenomena lean to one parent and certain 

 others to the other parent, but the relationship is, on 

 the whole, distinctly closer to N. eleyans. In comparison 

 with the starches of the parents the starch of the hybrid 

 N. queen of roses contains a larger number of aggregates 

 which have a larger number of component grains, and 

 more compound grains than in either parent; and the 

 latter are like those of N. elegans; the grains are less 

 regular than those of 2V. elegans but more regular than 

 those of N. crispa. The hilum is as distinct as in 

 2V. crispa and more distinct than in the other parent; 

 it is rarely fissured, thus being closer to 2V. elegans; 

 and the eccentricity is greater than in either parent, 

 being nearer 2V. elegans. The lamellae in characters and 

 arrangements closely resemble those of 2V. crispa, but 

 the number is less than in either parent and closer to that 

 of 2V. elegans. In size the grains are smaller than those 

 of either parent, and closer to those of 2V. elegans. In 

 the polarization, selenite, and qualitative reactions with 

 iodine the resemblances are closer to 2V. elegans. In the 

 qualitative reactions with chloral hydrate, nitric acid, 

 potassium iodide, potassium sulphocyanate, potassium 

 sulphide, and sodium salieylate certain of the phenomena 

 lean to one parent and certain others to the other. In 

 the reactions with chloral hydrate and sodium salieylate 

 they, on the whole, more closely resemble those of 2V. 

 crispa, but those with nitric acid, potassium iodide, potas- 

 sium sulphocyanate, and potassium sulphide more closely 

 resemble those of 2V. elegans. 



The two hybrids differ in certain very interesting 

 respects, especially as regards their greater resemblances 

 in their various properties to one or the other parent. 

 2V. dainty maid is in form more like 2V. crispa than 

 2V. elegans, but in other histological respects more like 

 the other parent. 2V. queen of roses is in form and 

 hilum more like 2V. elegans than 2V. crispa, but in the 

 lamellae it is nearer to 2V. crispa. In the polarization 

 properties both hybrids are closer to 2V. elegans than to 

 2V. crispa, N. queen of roses being closer than 2V. dainty 



maid. In the iodine reactions, both quantitative and 

 qualitative, 2V. dainty maid more closely resembles 2V. 

 elegans; but in the other hybrid, 2V. queen of roses, the 

 uuheated grains show a closer relationship to 2V. elegans 

 and the heated or gelatinized grains to the other parent. 

 In the aniline reactions 2V. dainty maid is closer to 2V. 

 elegans than to 2V. crispa; while 2V. queen of roses is closer 

 to 2V. crispa than to 2V. elegans. In the qualitative reac- 

 tions with the various chemical reagents similar curious 

 individualities are recorded, as regards interparental and 

 inter-hybrid and parental-hybrid reactions. The hy- 

 brids are sometimes practically alike and at others quite 

 as different from each other as they are from the parents, 

 or as the parents are from each other. The qualitative 

 reactions may be closer to one or the other parent, accord- 

 ing to the reagent. In the chloral-hydrate reactions both 

 hybrids are closer to 2V. crispa, 2V. dainty maid being 

 the closer. In the reactions with nitric acid, potassium 

 iodide, potassium sulphocyanate, and potassium sulphide 

 the hybrids are closer to 2V. elegans, N. dainty maid being 

 the closer. In the sodium-salicylate reactions 2V. dainty 

 maid is nearer to 2V. elegans, and 2V. queen of roses nearer 

 to 2V. crispa, there being nearly as much difference be- 

 tween the hybrids themselves as between the hybrid 

 2V. queen of roses and the parent 2V. elegans.

2V. crispa shows a higher reactivity than the other 

 parent 2V. elegans in the reactions with polarization, gen- 

 tian violet, safraniu, and temperature, and a lower reac- 

 tivity with iodine. Both hybrids in the polarization and 

 iodine reactions are nearer to 2V. elegans than to the other 

 parent, 2V. dainty maid having the same polarization 

 reaction as this parent, but a higher iodine reaction.
