Drosera, Pinrjuicula, &c., and other genera. From these experi- 

 ments, the author considers it estabhshed that chlorophyll-grains 

 are re-formed after being broken up ; he further considers that 

 these contain living protoplasm, to which may be attributed their 

 various movements. 



April 6. — Sir John Lubbock, President, in the chair. — Messrs. 

 John Blackie, C. C. Lacaita, J. W. Phillips, and John B. Wilson 

 were elected Fellows of the Society. — Mr. Patrick Geddes exhibited 

 and described a series of living specimens under the microscope 

 illustrative of the presence of Algae in Radiolarians and certain 

 forms of Coelenterata. — The following papers were read : ' On 

 the Connection between Geotropism and Growth,' by Mr. Francis 

 Darwin. — ' Note on Negative Heliotropism in Fumaria coryvibosa,' 

 by Mr. B. Day don Jackson. M. Battandier has noticed that in 

 this plant, which grows in the crevices of overhanging rocks, the 

 pedicels after flowering lengthen out, and deposit the fi'uits in such 

 crevices as may be within reach. — ' Some Observations on the 

 Breaking of the Shropshire Meres,' by Mr. William Phillips. The 

 phenomena locally known as "breaking" usually occurs in autumn, 

 and is caused by the rapid development of the following AlgaB, viz. : 

 Echinella articulata, Anabania circinalis, Cylindrosjjermum Ralfsii, 

 Splmrozijya Carmichaelii, and Ccelosphcuriiun Kutzingianum. The 

 author specially draws attention to the fact that the phenomenon 

 has this year occurred in the month of February. 



April 20. — Sir John Lubbock, President, in the chair. — Sir 

 Thomas D. Acland, Bart., M.P., was elected a Fellow of the 

 Society. — The President then addressed the Meeting, and made 

 some remarks upon the loss which science had sustained in the 

 death of Mr. Charles Darwin ; and, as a tribute of respect to his 

 memory, he moved that after the formal business was concluded 

 the Meeting should adjourn. 



May 4. — Sir John Lubbock, President, in the chair. — Dr. 

 Cuthbert C. Gibbes was elected a Fellow of the Society. — The 

 following papers were read : ' On a Collection of Algse collected in 

 the Himalayas,' described by Prof. Dickie, F.L.S. — 'On new 

 varieties of the Sugar-Cane produced by planting in apposition,' 

 by the Baron de Villa Franca, and Dr. Glass, Superintendent of 

 the Botanic Garden, Eio de Janeu'O, communicated by the late 

 Charles Darwin. Li correspondence which had passed between 

 the above-mentioned gentlemen, Mr. Darwin had expressed doubts 

 as to whether two varieties could affect the character of the buds 

 produced by either, it appearing more probable to him that the new 

 variety was due to bud- variation. The Baron de Villa Franca 

 thereupon forwarded a document signed by eight distinguished 

 Brazilians, testifying to the fact that valuable varieties have been 

 raised by the process in question. Dr. Glass furthermore describes 

 in detail his early but fruitless attempts to graft two varieties of the 

 sugar-cane, though he succeeded with another monocotyledon, viz., 

 Draccena. — ' Notes on some Cape Orchids, with a list of published 

 species of Cape Orchids,' by Harry Bolus, F.L.S. — ' Note on the 

 Dimorphic Florets of Catananche lutea,' by B. Daydon Jackson.
