EXTRACTS FROM PROCEEDINGS- 



lxvii 



June 16, 1868. 

 A. Murray, Esq., in the Chair. 



The Minutes of the last Meeting were read and approved. 



Two letters from Mr. Gr. Maw, respecting the coloured shades 

 proposed for experiment, were read. 



Major Clarke made some observations on the effect of coloured 

 glasses on the colouring of Dahlia-flowers. 



Yellow and red were as darkness, blanching the flowers. 



Deep blue made the colouring more intense, while the effect of 

 green was intermediate. 



A white Calceolaria, which he hoped would prove permanent, 

 had been produced under the influence of coloured glass. 



It was recommended that similar experiments should be carried 

 out at Chiswick. 



Mr. Lee, of Clevedon, sent diseased pears, cherries, &c, which 

 were unfortunately almost in a state of putrescence. The pears 

 were, however, still in such a state as to make it probable that 

 they suffered from the effect of frost, which in the first instance 

 attacks the stigmas, which, sooner or later, according to the degree 

 in which they have suffered, communicate a taint to the ovules, 

 and from thence to the surrounding tissue. It was observed by 

 Dr. Masters that the lining at the base of the calyx sometimes 

 suffers even sooner than the stigmas. 



Dr. Hogg exhibited monstrous flowers of the common foxglove, 

 in which the corolla was much enlarged by fusion, and the stamens 

 and pistils had undergone various modes of transformation. 



A conversation then arose respecting the effect of manure, the 

 failure of attempts to make artificial farmyard manure, and the 

 beneficial effects of cotton-cake on cotton, hopbines on hops, and 

 the primings of vines on vines, also of nitrate of soda on cotton. 



Specimens of Meseda Phyteuma were exhibited by Major Clarke 

 as the possible parent of the garden Mignonette. 



Mr. Reeves brought specimens of Strawberries, in which the 

 petals were not deciduous, though the fruit was large and per- 

 fectly developed. 



Finally, it was proposed that Dr. Voelcker should report on the 

 effects of different manures on vegetation at the next Meeting. 



The Committee then adjourned.
