' xxii PKOCEEDINGS OF THE EOYAL HORTICULTURAL SOCIETY. 
but as El result of good cultivation they have now reached the size 
represented by sample 8a. 
No. 9.— Specimens of the large white Fir-apple Potato. 
No. 10.--Specimens of the small white Fir-apple Potato. 
No. 11. — Specimens of the red Fir-apple Potato. These three Potatps 
produce flowers, but no berries. The foliage, generally speaking, corre- 
sponds with that of other Potatos, and is quite unlike No. 8. 
Besults of Sowing Tomato Seed saved from Potato Plant grafted 
loith Tomato. 
1895. — In this year a scion of Potato Victoria was grafted with 
Tomoto Maincrop. Seed was saved in the autumn of 1895. 
1896. — Seed sown, several plants raised, and seed again saved. 
1897. — Seed from last year's trials sown in the spring, and ten or 
twelve plant? ,put out in the open in June. It was evident on c omparing 
these plants with several trials of the true Mainsrop Tomato gro wing 
alongside that the graft had materially affected the variety, which 
happens to have very distinctive characteristics, the leaves of Maincrop 
being exceptionally large, massive, and almost entire in outline, generally 
at least three times the size of those of the ordinary Tomato ; the plants 
of the seedling appeared quite distinct from the true Maincrop ; t here 
were many more fruits on each plant, and these fruits were decidedly 
smaller and earlier, and more corrugated. The leaves, however, were 
similar in character, but decidedly smaller. Seed was again saved from 
these plants. 
1898. — Seed sown again, and the same number of plants put out in 
June. The 1897 notes were entirely confirmed, but the contrast between 
these plants and those of the true Maincrop Tomato growing alongside 
was perhaps more marked than in the preceding year. 
Holli/hock Disease. — Leaves attacked by Puccinia malvacearum, a 
fungus which has proved fatal to these plants for many years, were 
received from Mr. Molyneux. 
Eucalyptus sp. — Dr. Masters showed a flowering specimen of E. 
cordatus, growing in the open air inco. Down ; and of E. globulus, grown 
for forty years in Leicestershire. Professor Balfour observed that on 
the coast of Ross-shire several plants characteristic of the Riviera thrive 
well, in consequence of the amelioration of the climate by the proximity 
of the Gulf Stream. 
Cypripedium. — Dr. Masters exhibited a blossom of a Cypripedium in 
which the two normally coherent sepals were free. 
Fasciated Cyclamen. — Dr. Masters exhibited specimens of this not 
unusual phenomenon of several flowers with leaves on the same stem. 
Scientific Committee, February 14, 1899. 
Mr. McLachlan, F.R.S., in the Chair, and four members present. 
Diseased Apple-tivigs. — These were received last December from Rev. 
A. Foster-Melliar. Dr. W. G. Smith, after a prolonged and difficult investi- 
gation, has pronounced the disease to be due to bacteria, and forwarded the
