120 Address. [Feb. 



among wliicli three are new, and nine species occurring on grasses and 

 sedges. Dr Prain has contributed the first instalment of a series of papers 

 entitled Novicice Indicce, containing diagnoses of some additional species 

 of Pedicularis new to India. Dr. G. King's paper on " Materials for 

 a Flora of the Malayan Peninsula " is the first part of a systematic 

 account of the Malayan plants indigenous to British India, including 

 Burma, the Malay Peninsula, the Straits Settlements and the Andaman 

 and Nicobar Islands, and includes the Bammculacece, MagnoUacece, 

 Menispermacece, NympJiceacece, Gapparideoe and Violacem. 



Of the new " Annals of the Royal Botanic Garden, Calcutta " 

 brouo-ht out by Dr. King, the two volumes mentioned last year as under 

 preparation have been completed and published. One is an Appendix 

 to Vol. I, dealing with new species of Ficus from New Guinea and 

 containing an account of the phenomena of fertilisation in Ficus 

 Roxhiirgliii, by Dr. D. D. Cunningham. The volume is illustrated with 

 lithographed plates and a heliogravure plate of Ficus Roxhurghii, from 

 Dr. Cunningham's photograph. The other. Vol. II, contains descriptions 

 of the species of Artocarpus, or Bread-Fruits and Jacks, indigenous to 

 British India, within the geographical limits noted above, and of the 

 Indo-Malayan species of Quercus and Gastanopsis, Oaks and Chestnuts, 

 and is also largely illustrated with lithographed plates. 



The principal botanical papers in last year's volume of the Scientific 

 Memoirs by Medical Officers of the Army of India, were noticed in my 

 last address. The foi'thcoming number, now almost ready for issue, 

 will contain papers by Dr. D. Prain on the Laccadive plants collected 

 by Mr. Alcock in the "Investigator," in 1888-89, and by Mr. A. 0. 

 Hume, in 1875 ; by Dr. A. Barclay on the life-history of a Himalayan 

 Qi/vinosporangium, (G. Gunningliamianum, n. sp.), on Pyrus PasJiia and 

 Cupressus torulosa ; also on a Ghrysomyxa on Rhododendron arboreum, 

 (C. Mmalense, n. sp.) ; and on the life-history of a Uredine on Rtibia 

 cordifolia (Puccinia Gollettiana, n. sp.) ; also a valuable and important 

 paper, by Dr. D. D. Cunningham, on Milk as a medium for Choleraic 

 Comma-bacilli, in which he shows that milk as ordinarily supplied for 

 consumption in this country, from the high degree to which it is nor- 

 mally contaminated by schizomycetes whose gi'owth is associated with 

 processes of acid fei'mentation, is not a favourable medium for the 

 development or continued existence of the Comma-bacilli or other 

 schizomycete organisms which require an alkaline or neutral envi- 

 ronment. A curious and striking fact brought out in the course of these 

 observations was the difference in the phenomena presented by portions 

 of milk from one and the same sample according to the level in the 

 fluid from which they were taken — and it is shown that specimens
