SCIENTIFIC COMMITTEE, JUNE 11. 



xxxvii 



la. " Solamim tuberosum, wild species," from seed saved from the 

 foregoing at Reading in 1906. 



lb. " Solamim tuberosum, wild species." Seedling plants raised from 

 seed received from Vermont in 1907. 



These three lots of seedlings so far exhibit no variations, but promise 

 to come quite true from seed, and to be uniform in character. 



lc. Seedlings raised by crossing No. 1 with pollen from white-flower- 

 ing Solamim Commersonii at Reading in 1906. 



Id. Seedlings from No. 1 crossed with pollen of Solatium etuberosum. 



2. " Solatium tuberosum (neiu wild species)" collected in Mexico. 

 Grown from seeds saved at Vermont in 1906. 



3. Solatium Maglia. Grown from tubers received from Mr. Baker of 

 lew in 1886. 



4. Solamim verrucosum. Grown from tubers raised from seed 

 received from Vermont Agricultural Experiment Station, 1906. 



4a. S. verrucosum seedlings from seed saved from No. 4 at Reading 

 in 1906. 



4b. S. verrucosum raised from seed received direct from Vermont, 

 1906. 



5. S. polyanthemum from seed received from Vermont in 1906. 



5a. S. polyanthemum from seed saved at Reading from tubers raised 

 from No. 5. 



It is remarkable that seedlings of all the above wild types appear 

 to come true and quite uniform, when it is remembered that in the case 

 of no cultivated potato do the seedlings come either uniformly true to 

 each other or to the parent. 



A hearty vote of thanks was accorded to Mr. Sutton for his very 

 interesting and comprehensive exhibit. 



Scientific Committee, June 11, 1907. 



Sir J. T. D. Llewelyn, Bart., in the Chair, and seventeen other 

 members present. 



The late Dr. M. T. Masters, F.B.S.— The Chairman, Sir J. T. D. 

 Llewelyn, after referring in sympathetic terms to the loss the Committee 

 had sustained in the death of Dr. Masters, who had for so long presided 

 over the deliberations of the Committee, a loss which would be felt not 

 only by them, but by the whole Society, and by the whole horticultural 

 world, moved that a letter of condolence should be sent to his family. 

 Dr. Cooke, V.M.H., seconded the motion, and it was carried by all the 

 members of the Committee upstanding in their places. 



Genetics. — Mr. Chittenden reported that he had received a communica- 

 tion from Mr. Bateson concerning the proposed meetings for the special con- 

 sideration of the progress in the study of Genetics, brought forward at a 

 recent meeting by Mr. A. Worsley. Mr. Bateson expressed himself in 

 sympathy with the scheme. Mr. Chittenden also announced that Mr. 

 Biffen would, at the next meeting, show a series of hybrid sweet peas to 

 illustrate the Mendelian laws of inheritance.
