no such parent is urowinu' in the same proximitv as is the case with 

 the white flowered type. \u)V the present, tiierefoie. it is impos- 

 sible to say what relation exists Ijetweeii the two conditions which 

 may be indicated by the pivseiiee and al)sence of the pale- vellow 

 factor. This [)()iiit is now under investigation, itiscleai-. however, 

 that this condition does not corres[)ond with that denoted bv Halls 

 (2) as lemon yellow which he found to represent the impure sta<4e 

 in tlie cross between full yellow and wliite flowered parents in the 

 lilgvptian cottons.

As has been noted under the description of tvpes all true 

 Indian cottons possess an eye situated at the base of the petal. 

 In some of the forms received from China, howexci-. the petal i> 

 self-coloured yellow. These cottons exhibit complete feililitv in 

 the cross with the Indian types and the cond»ined group, therefore. 

 is, in res[)ect to this character. comparai»l<' to the lyuA'ptiaii series 

 of cotton in which tin' e\'e mavor ma\" not be nresciit. IJalls 

 (2) has shown that in the latter group the liet eio/.x'gote is repre- 

 sented b\' plant in which the inteiisitx' ol the e\'e colour is much 

 reduced. In the examples we haxc obserx'ed such an intermediate 

 condition appears to be rare or non-existent. .Vt the present time 

 crosses in which the eyeless h)rm figures as parent ha\e n(»t been 

 carried sullicietitlv far the eveless t\|)e being onl\- recently 

 acquired — to sup[)lv dehnile iidormatioii of the Ixdiaxiour ol this 

 character. In the F, geneiation of a cross bt'tween this h)rm and 

 Type 3 the eye is fully develo])ed. but it is po.ssible that the red sap 

 colour of Type 3 may act as a masking chaiaoter. Indirect evidence
