HISTOLOGIC PROPERTIES AND REACTI' 



With gentian violet and safranin N. dainty maid is the 

 same as N. elegant, while N. queen of roses is the same 

 a> .V. i ri</>a. In the temperature reaction- the hybrids 

 are interi: N. dainty maid 



elegant, and N. queen of roses closer to N. crispa. N. 



dainty maid is, on the whole, more closely related in 



the pollen parent, and N. queen of 



i parent.

Velocity-beaction CtJBVES. 



This section deals with the velocity-reaction curves of 

 the starches of Xerine crispa, N. elegans, N. dainty 

 maid, and N. queen of roses, showing the quantitative 

 differences in the behavior toward different reagents at 

 definite time-intervals. (Charts D 190 to D 210.) 



Among the conspicuous features of these charts are: 



(1) The mar --of all four curves, except- 



the reactions with chloral hydrate and potassium 



sulph. . in which there is a marked tendency to 



separation, - illy in the former, although in the 



general course of curves the characters of the reactions 



In the reactions with pyrogallic acid, sulphuric 



acid, hydrochloric acid, potassium hydroxide, sodium 



sulphide, calcium nitrate, copper nitrate, cupric chloride, 



barium chloride, and mercuric chloride gelatinization 



occurs either with such rapidity or slowness that there is 



tisfactory differentiation, such differences as are 



noted falling within the limits of error of experiment 



or being unimportant. Even in some of the other reac- 



differences are small.
