Tin* M-ction treat* of the re* . of the 



hvhrid as regard* nameneas, inUrmodiatenee*, exec**, 

 UM detu-it in relation to the parent*. (Table A 4 and 

 Chart* 1> -i.) 



The reactivities of the hybrid are the Mine M thoae 

 of the seed pan-nt in not a single n-.i 

 thoee f the pollen parent with iodine and sulphuric i.l ; 

 the ume a* those of both parent* with lafranin, potas- 

 sium sulphide, calcium nitrate, uranium nitrate, cobalt 

 nitrate, copper nitrate, cupric chloride, barium rhl 

 and mercuric chloride; intermediate with hydrochloric 

 acid, potassium hydroxide, potassium i'li.|.-. pota 

 ftulphocyanate, sodium hydroxide, and strontium nitrate 

 (in three reactions being closer to those of the seed parent 

 and in three mid-intermediate) ; highest with polariza- 

 tion, temperature, chromic n< ul. pvmgallir ncnl, and 

 nitric acia (in one being closer to the pollen parent, in 

 three closer to the seed parent, and in one ait close to one 

 as to the other parent) ; and the lowest with gentian 

 violet, chloral hydrate, sodium sulphide, and sodium 

 salicylate (in two being closer to the jMilleii parent, in one 

 closer to the seed parent, and in one as close to one aa 

 to the other parent). 



The following. is a nummary of reaction-intensities : 

 Same as seed parent, 0; same as pollen parent, V ; same 

 as both parent*, 9 ; intermediate, 6 ; highest, 5 ; lowest, 4. 



In none of the reactions is there sameness to the seed 

 and in only two is there sameness to the pollen parent; 

 and in termed iateness is scarcely more frequent than de- 

 velopment in excess or deficit of parental extremes. Pa- 

 rental influences on the starch of the, hybrid seem to be 

 somewhat in favor of the seed pan-nt. 



COMPOSITE CURVES OF TICK REACTION-! STKNBITIES. 



This section treat* of the composite curves of the 

 reaction-intensities showing the differentiation of the 

 starches of Hippttutrum daonen, //. ttphyr, and //. 

 dtronet-zephyr. (Chart K I.) 



The most conspicuous features of this chart are: 



I I ) The closeness of all thm- cur 



(2) The curve of //. daones. excepting in the pola- 

 rization reaction, is higher than the corresponding reac- 

 tions of //. zephyr in the reaction*) with iodine, gentian 

 violet, chloral hydrate, chromic acid, pyrogallic acid, 

 nitric acid, sulphuric acid, hydrochloric acid, potasium 

 hydroxide, potassium iodide, potassium sulphocyanate, 

 sodium hydroxide, sodium sulphide, and strontium ni- 

 trate; lower with polarization ; and the same or practi- 

 cally the same with safranin, temperature, potaasium 

 sulphide, sodium salicylate, calcium nitrate, uranium ni- 

 trate, cobalt nitrate, copper nitrate, cupric chloride, 

 barium chloride, and mercuric chloride*. 



(3) In //. dttonet, the very high reaction* with 

 polarization, chromic acid, and aulphuric acid : the high 

 with pyrogallic acid and sodium salicylate; the moderate 

 reactions with iodine, gentian violet, safranin, and hy- 

 drochloric acid ; the low reactions with temperature, 

 chloral hydrate, nitric acid, potaasinm hydroxide, potas- 

 sium sulphocyanate, and sodium hydroxide; and the very 

 low reactions with potassium iodide, potassium sulphide, 

 sodium sulphide, calcium nitrate, uranium nitrate, 

 xtrontium nitrate, cobalt nitrate, copper nitrate, cupric 

 chloride, barium chloride, and mercuric chloride reaction*. 



(4) In //. zephyr, the very high reaction* with polar- 

 ization and sulphuric acid; the high with chromic acid, 

 pyrogallic acid, and sodium salicylate; the moderate 

 with iodine, gentian violet, and safranin ; UM low with 

 temperature, nitric acid, hydrochloric acid, potaasium 

 hydroxide, and pota*inm ralphocyanaie; the very low
