small flies, etc., of which there was usually a plentiful supply on — 
bogs. He dealt briefly with the British species of Sundews, Butter- 
worts, and Bladderworts, pointing out their salient features and 
the different ways in which they secured their animal food. He 
reminded his audience that the well-known Venus’s Fly-trap 
(Dionea muscipula) belonged to the Sundew family, and that an 
Italian liqueur was made from another member of the family 
and called Rossoli, a word derived from Ros solis, the Latin equiva- 
lent of sun-dew. 
Mr. Nicholson then passed on to the consideration of the 
non-insectivorous bog-plants, explaining that he only proposed 
to refer to such plants as were practically exclusively confined 
to peat-bogs, although he admitted that in some cases it was 
difficult to draw the line. He omitted the cryptogams, except 
Lastrea cristata and Osmunda regalis, and also the sedges, grasses 
and rushes, confining his remarks to the five species of British 
Bog-Orchids and thirty-four other species of British plants belonging 
to twenty-three families, among which may be mentioned Narthe-- 
cium ossifragum, Viola palustris, Hydrocotyle vulgaris, Parnassta 
palustris, Anagallis tenella, Wahlenbergia hederacea, Sibthorpia 
Europea, and Gentiana pneumonanthe. 
Mosses, chiefly Sphagnacez, were exhibited by Mrs. Beach ; 
a series of sinistral and dextral shells by Mr. Hugh Findon ; and 
specimens of bog plants by Mr. L. B. Hall, F.L.S.

Three demonstrations (with specimens and blackboard sketches) 
were given: ‘‘The Five Banded Snails of London,” by Mr. 
Hugh Findon; ‘‘Star Fishes,’’ by Mr. P. Macleod Yearsley,
