Mr. William Phillips. The phenomena locally known as „breaking" usually 

 occurs in autumn, and is caused by the rapid development of the tbllowing 

 Algse, viz. : Echinella articulata, Anabsena circinalis, Oylindrospermmu Ralfsii, 

 Sphferozyga Carmichaelii , and Coelosphserium Kützingianum. The author 

 specially draws attention to the fact that the phenomenon has this year oc- 

 curred in the month of February. 



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

 D. Acland, Bart., M. P., was elected a Fellow of the Society. The Pre- 

 sident 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 bis memory, he moved that after the formal business 

 was concluded the Meeting should adjourn. 



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

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

 papers were read : ,0n a Collection of Algge collected in the 

 Himalayas,' described by Prof. Dickie, F. L. S. - ,0n new varieties 

 oft he Sugar-Cane produced by planting in apposition,' by 

 the Baron de Villa Franca, and Dr. Olass, Superintendent of the Botanic 

 Gai-den, Rio de Janeiro, couimunicated by the late Charles Darwin. In 

 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 hini 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 bis early 

 but fruitless attempts to graft two varieties of the sugar-cane, though he 

 succeeded with another monocotyledon, viz., Dracsena. — , Notes on some
