author of ■ British Forest Trees,' who died at Twisel House on the 27th March 
last, aged seventy-nine ; and 3. Mr. David Tennant, an associate of the Society, 
died at Pittenweem, on 22nd March last, in the seventy-eighth year of his age. 
He was the younger brother of the late Professor Tennant, of St. Andrew's, and 
was for thirty- seven years schoolmaster at Denino. The following communi- 
cations were read :— 1. On Silicified Vegetable Structures from the Zambesi. 
By Dr. John Lowe, Lynn. While examining some mud brought from the 
neighbourhood of the Zambesi Falls, and given to him by Mr. Baines, Dr. 
Lowe's attention was arrested by some peculiarly-shaped bodies, which ap- 
peared in great numbers. They presented a variety of well-defined and con- 
stant forms, and at first he had considerable difficulty in determining their 
nature. After repeated examination he found some of them arranged together 
w their natural positions, which showed that they were silicified plant-cells. 
The mud had been boiled for a long time in nitric acid, and subsequently in 
iquor potass®. The bodies in question then appeared as transparent siliceous 
particles mixed with some fine Diatomacea. The author described the various 
forms met with. 2. On the Progress of Cinchona Cultivation in India. By 
an Indian Correspondent. Communicated by Professor Balfour. 3. Notice 
of Cinchona Planting in the Kangra Valley. By William Coldstream, E*q., 
■B.A. The Kangra Valley is situated at the foot of the lofty Chumba Hills, 
whose peaks rise, at a distance of four or QYe miles, to the height of 14,000 or 
i W teet. The first experiment was begun some two years ago in a sheltered 
mine above 5000 feet above the sea, in the midst of a forest of "chil." There 
the plants grew luxuriantly, but last winter a heavy fall of snow covered them 
and killed them all. In the beginning of 1866 ground was bought some six 
miles lower clown the slope of the valley, at an elevation of about 4000 feet, 
Where the snow never lies. Ten acres have been planted, and a large number 
° f the plants are looking most vigorous. 4. On New Zealand * Carrageen." 
^ J W. Lauder Lindsay, M.D. Dr. Lindsay, in a memorandum appended to 
paper on Otago Alga3, printed in the Society's ■ Transactions' for last session, 
expressed the opinion that the seaweed variously designated by New Zealand 
settlers^ "Carrageen," "Irish Moss," " Edible Seaweed," and " Chondrus 
spu$, would probably prove to be a species of Gigartina. A note subse- 
quently received by the author from Mr. Cooke, of the India Museum, 
London, confirms that opinion, and makes it probable that all the various 
esignahons above given apply to the same New Zealand species, Gigartina 
mda > whi ch is abundant on the Greenisland coast of Otago. Such desig- 
ions as " Carrageen " furnish a good example of the confusion, if not error, 
rising from the application to New Zealand plants, by the settlers, of the ver- 
acuiar names of British plants to which the New Zealand plants in question 
supposed to possess some resemblance, either as regards their uses or ap- 
P ranee. A similar instance among cryptogams is to be found in the term 
rc le ha weed." Among phanerogams, illustrations of this mal-appropriation 
*c T erms are muc h more numerous and striking. 5. On the Botany of the 
archn" of Mont Blanc. By Dr. Buchanan White. In this communication 
e autnor gave an account of an excursion which he made to the " Jardin" on 
a 
°nt Blanc, in September, 1866. In a paper by Professor Martins in the
