with reagents of suitable concentration there would 

 be shown marked differentiation. Attention has been 

 directed to greater resemblance generally of the 

 hybrid to L. maculatum than to the other parent 

 in histologic and certain qualitative peculiarities, and 

 ;ii o in the reaetion-intensitie expressed by light, color, 

 and temperature reactions, and it is of interest in thi6 



connection to note thai in the react - with calcium 



nitrate, uranium nitrate, cobalt nitrate, copper nitrate, 

 cupric chloride, and barium chloride the figures show 



very definitely the same parental relat ship, while in 



that with strontium nitrate the hybrid figure approxi 

 mates mid-intermediateness, and in that with mercurii 

 chloride a reactivity higher than in either parent. In 

 the remaining reactions, all of which being less rapid, 

 with chloral hydrate the reaction of the hybrid is prac 

 tieally mid-intermediate; with chromic arid and pyro- 

 gallic aeid the reactions are closer to //. maculatum; and 

 with sodium salicylate the reaction is at the end of 3 

 minutes distinctly lower than those of the parents and 

 at 5 minutes mid-intermediate. Referring to the charts, 

 it will be seen that in all five reactions the curve of L. 

 martagon album is the lowest of the three; that the 

 hybrid curve is practically the same as the curve of L. 

 maculatum in the reactions with chromic acid, pyrogallic 

 acid, and barium chloride; that the hybrid curve is 

 intermediate in the chloral-hydrate reaction, but on the 

 whole closer to L. maculatum ; and that the hybrid curve 

 is lower at first than that of either parent, and then inter 

 mediate, in the sodium salicylate reaction. 



Reactiox-intensities of the Hybrid. 



This section treats of the reaction-intensities of the 

 hybrid as regards sameness, intermediateness, excess, and 

 deficit in relation to the parents. (Table A '.'."> and 

 Charts D347 to D 353.) 



The reactivity of the hybrid is the same as that of the 

 seed parent in none of the reactions; the same as those 

 of the pollen parent in the reactions with polarization, 

 chromic acid, pyrogallic acid, copper nitrate, and cupric 

 chloride: the same as those of both parents with nitric 

 acid, sulphuric acid, hydrochloric acid, potassium hy- 

 droxide, potassium iodide, potassium sulphocyanate, 

 potassium sulphide, sodium hydroxide, and sodium sul- 

 phide, in all of which the reactions occur too rapidly 

 for differentiation; intermediate with iodine, chloral 

 hydrate, uranium nitrate, strontium nitrate, cobalt ni- 

 trate, and barium chloride (in four being closer to the 

 seed parent, and in four closer to the pollen parent) ; 

 highest with mercuric chloride, and as near one as the 

 other parent; and lowest with gentian violet, safranin, 

 temperature, sodium salicylate, and calcium nitrate (in 

 three being (loser to the pollen parent ami in two closer 

 to the seed parent). 



The following is a summary of the reaction-intei 

 tie-: Same as seed parent, 0; same as pollen parent. 5; 

 same as both parents, 9; intermediate, t'> ; highest, 1: 

 lowest, 5. 



The pollen parent has obviously exercised a much 

 more potent influence than the other parent on the proper 

 ties of the March of the hybrid. The most conspicuous 

 features of these reactions, apart from the many insta 

 of sameness to both parents, are sameness to the pollen 

 parent, intermediateness, and lowest rea tivities. 



Composite Curves of Reactiox-in'tkn'sitif.s. 



This section treats of the composite curves of the 

 reaction-intensities, showing the differentiation of the 

 starches of I, ilium martaqon alburn, L. maculatum, and 

 L. marhan. (Chart E 25.)
