showing the differentiation of the 

 starches of Lilium martagon, L. macviatum, and L. 

 dalhansoni. (Chart K 26.) 



The most conspicuous features of this 'hart are: 



(1) The clo e e in the three cui 

 excepting in the reactions with chromic acid, pyrogallic 

 acid, and barium chloride, in which then irs in each 

 instance a marked drop in the curve of h. marta 

 while the curves of L. macviatum and the hybrid b ad 

 to keep the same or quite ■ In a large 

 number of reactions there is no differentiation bet 



the three starches, as in those with chloral hydrate, 

 nitric acid, sulphuric acid, hydrochloric acid, potassium 

 hydroxide, potassium iodide, potassium sulphocyanate, 

 mm sulphide, sodium hydroxide, sodium sulphide, 

 and uranium nitrate; and in other instances there 

 tendency for the hybrid curve to he the Fame as that of 

 one or the other parent, or occasionally above both ot 

 intermediate. In part the hybrid curve is more dis- 

 tinctly related to the curve of £. maculatum than to that 

 of the other parent, and in part the reverse. 



(2) In L. martagon in comparison with the other 

 parent, the high reactions with polarization, iodine, gen- 

 tian violet and safranin; the same or practically the 

 same with chloral hydrate, nitric acid, sulphuric acid, 

 hydrochloric acid, potassium hydroxide, potassium 

 iodide, potassium sulphocyanate, potassium sulphide, 

 sodium hydroxide, sodium sulphide, calcium nitrate, 

 uranium nitrate, and mercuric chloride; and the lower 

 with temperature, chromic acid, pyrogallic acid, sodium 

 salicylate, strontium nitrate, cobalt nitrate, copper ni- 

 trate, cupric chloride, and barium chloride. 



(3) In L. martagon the very high re with 

 chloral hydrate, nitric acid, sulphuric acid, hydrochloric 

 acid, potassium hydroxide, potassium iodide, potassium 

 sulphocyanate, potassium sulphide, sodium hydroxide, 

 sodium sulphide, sodium salicylate, calcium nitrate, ura- 

 niuni nitrate, strontium nitrate, cobalt nitrate, copper 

 nitrate, cupric chloride, and mercuric chloride; the high 

 reactions with polarization, iodine, chromic acid, pyro- 

 gallic acid, and barium chloride; and the moderate reac- 

 tions with gentian violet, safranin, and temperature. 



(-1) In L. macviatum the very high reactions with 

 chloral hydrate, chromic acid, pyrogallic acid, nitric 

 acid, sulphuric acid, hydrochloric acid, potassium hy- 

 droxide, potassium iodide, potassium sulphocyanate, po- 

 tassium sulphide, sodium hydroxide, sodium sulphide, 

 sodium salicylate, calcium nitrate, uranium nitrate, 

 strontium nitrate, cobalt nitrate, copper nitrate, barium 

 chloride, and mercuric chloride; the high temperature 

 reaction; the moderate reactions with polarization, 

 iodine, gentian violet, and safranin. 



(5) In the hybrid, the very high reactions with 

 chloral hydrate, chromic acid, pyrogallic acid, nitric 

 acid, sulphuric acid, hydrochloric acid, potassium hy- 

 droxide, potassium iodide, potassium sulphocyanate, po- 

 tassium sulphide, sodium hydroxide, sodium sulphide, 

 sodium salicylate, calcium nitrate, uranium nitrate. 

 strontium nitrate, cobalt nitrate, ci p er nitrate, cupric 



ride, barium chloride, and mercuric chloride; the 

 high reactions with polarization and iodine : and the mod- 

 erate reactions with gentian violet, safranin, and 

 temperature.
