COMPOSITE CURVES or RSACTION-INTKNSITIHI. 



This section treat* of the composite curve* of the 

 reaction-intensities, showing Uic dinYn>nti:itii>n .if the 

 starches of Lilium martagon, L. maculatum. am! /. 

 (io/Aaiuoni. (Chart E 26.) 



The most conspicuous feature* of this chart are: 



(1) The clo*e correspondence in the three curves 

 excepting in the reactions with chromic acid, pyrognllic 

 acid, and barium chloride, in which there occurs in i-arb 

 instance a marked drop in the curve of L. marln 

 while the curve* of L. maculatum and the hybrid t> n<l 

 to keep the name or quite clow? tn^i-tlii-r. In H lar^<- 

 number of reactions there is no differentiation between 

 the three starches, as in those with chloral hydra!.-, 

 nitric acid, sulphuric acid, hydrochloric acid, pota-'ciuin 

 hydroxide, potassium iodide, potassium sulphocyanate, 

 potawium sulphide, sodium hydroxide, sodium sulphide, 

 and uranium nitrate; and in nthi-r instance* there is a 

 tendency for the hybrid curve to be the same as that of 

 one or the other parent, or occasionally above both or 

 intermediate. In part the hybrid curve is more dis- 

 tinctly related to the curve of /,. mamlattim 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 

 name 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, pyro^allic acid, sodium 

 salicylate, strontium nitrate, cobalt nitrate, copper ni- 

 trate, cupric chloride, and barium chloride. 



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

 chloral hydrate, nitric acid, sulphuric acid, hydrochloric 

 acid, potassium hydroxide, potassium iodide, potassium 

 sulphocyanate, potassium sulphide, sodium hvdroxidn, 

 sodium sulphide, sodium salicylate, calcium nitrnt<>, ura- 

 nium 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. 



(4) In L. marulalum 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, 

 aodinm salicylate, calcium nitrate, uranium nitrate, 

 strontium nitrate, cobalt nitrate, copper nitrate, barium 

 chloride, and mercuric chloride; tbn hiirli t'-miN-rnturc 

 reaction ; the moderate reaction* 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, 

 ?odinm salicylate, calcium nitrate, uranium nitrate, 

 strontium nitrate, cobalt nitrate, copper nitrate, cupric 

 chloride, barium chloride, and mercuric chloride; the 

 hi^li reactions with polarization and iodine ; and the mod- 

 erate reactions with gentian violet, tafranin, and 

 temperature.
