the edges of the leaf, such as occur on Aloes, lVC, mav have had a 
mechanically deleterious effect on the intestine. 
Campanula, Species and Hybrids. — The Rev. C. Wollev-Dod sent 
specimens of the liowers of C. rotundifolia, C. rliomhoidalis, and their 
hybrid progeny; as well as of C. lactidora, both the typical flowers, and 
with an abnormal sub-polypetalous form. The following communication 
was also received from him : — " The form of corolla with narrow separated 
lobes, described and illustrated by De Candolle. Ponograph of Campjanula^ 
pp. 11, 12, lVC, and figured, plate ii. a, and also described by the late 
Professor J. S. Henslow (see De C, ^lonograph, p. 12), is commonest in 
C. lactidora (M. Biebj, in which it is always accompanied by narrow 
leaves. In C. rotundifolia it is commonest in broad-leaved forms, which 
I take to be hybrid, or are at least intermediate between C. rotundifolia 
and C. rliomhoidalis. These abnormal forms of C. rotundifolia are 
fertile, and the seedings come in part true, but always include many of 
the soldanelloid form — i.e. with a duplex corolla — which are also fertile. 
A study of C. rotundifolia and C. rliomhoidalis (apparently quite distinct 
and good species), and their variously-named intermediate forms, which 
Godron in his Flore de France calls * a httle chaos of species.' leads 
me to think that C. rotundifolia may be a species gradually crawling 
into new species which are not yet sufficiently deiined. In my garden 
the two species are united by imperceptible gradations, all of which 
are fertile. Forms having the characters of all the so-called species 
intermediate between ihese two may be picked out of them." 
Sweet Peas ^laljormed. — A curiously-flowered spray of Swee: Pea 
was sent by Mr. Pratt. Lion Gate, Richmond, every flower on the plant 
being similarly affected. An examination showed that the petals had 
remained crumpled up without having attained the usual subsequent 
expansion on blossoming. The stamens were twisted, but the anthers 
polhniferous, so that the stigmas were pollinated by self -fertilisation," 
the flowers being, in fact, cleistogamous. The flowers were arrested in 
growth, but it was impossible to assign a cause for their abnormal con- 
dition. 
Foliaceous Geranium. — A specimen of (apparently ) G. sanguineum 
was received from Mr. Bunyard, in which the petals of the flowers 
were replaced by green leaves the segments of which had remained con- 
duplicate.

Dr. M. T. Mastees. F.R.S., in the Chair. 
Grafted Potatos. — Mr. A, W. Sutton sent some specimens of the haulm 
and tubers of various Potatos upon which he had been experimenting. 
It wiQ be remembered that on January 31 Mr. Sutton (see page xx) 
exhibited numerous tubers the character of which appeared to have been 
modified in consequence of the plants from which they were grown having 
been gi*afted with Tomatos, 6iC. The plants now exhibited show that 
the modifications alluded to were not confined to the tubers alone, but 
were noticeable in the plants generally, and that there had been no rever- 
sion to the original form. The specimens exhibited were the follo\\ing : —
