The exhibitions held on each Saturday in January have been very interesting, as all the impromptu exhibitions are, owing partly to the discussions which take place at the same time The subject of the first discussion, January 10th, was the Native Grape, the essayist being W. N Barnett, of West Haven, Ct. The discussion was continued the following Saturday, and was long and animated. On the 22d of January E. S. Rand, Jr. made some interesting remarks on the orchids exhibited by him. January 29th W. H. Halliday read a paper on the growing of plants in Wardian cases, and that subject and the forcing of lilacs was discussed by various members of the Society. The principal plants exhibited have been the Orchids of E. S. Rand, Jr., who has shown the following fine varieties: Cypripedium insigne, an old well-known species, with thirty flowers. C. Harrisianum, a fine hybrid variety, with five flowers. Calanthc vestita ' rubra, with four very fine spikes of flowers, a very striking variety. Cattleya pumila, on a block of wood, a charming species from Brazil which remains some time in bloom.

Cirrhopetalum Medusae, a remarkable orchid, of which Williams, in his manual, says, "The flowers, though not large, are very numerous, and part of the sepals are very much lengthened, so that the spike looks like a head with long hair hanging down, from whence its name has been derived; it is a dwarf growing plant, with thick fleshy leaves." Laelia anceps, a superb plant, with five fine spikes of bloom; this is one of the best of orchids, it lasts a month or more in perfection if kept cool. Saccolabium giganteum, a very beautiful species, deliriously fragrant, and also very valuable on account of keeping in bloom a long time. This plant was in splendid order; it had been in bloom six weeks, and the flowers were apparently as fresh as when they were first expanded. Cattleya amethystoglossa, this is also a beautiful species, and as yet somewhat scarce; the flowers are very rich colored and attractive, and the specimen is the first exhibited. Mr. Rand has also shown very fine sprays of Thunbergia Har-risii and laurifolia, well-known stove climbers; also Aphelandra fascinator, recently sent out by Messrs. Veitch; the flowers are very bright and showy, and seed as freely as a morning glory.

James Comley has exhibited a new Amaryllis, Hendersonii, the beautiful Lapageria alba, Den-drobium nobile, Dracaena metallica (new), Lycaste Skinnerii, very fine specimens of lily of the valley in boxes; Cymbidium aloifolium, an old but choice species. C. M. Atkinson - Neapolitan and Maria Louise violets, good specimens, grown in pots. Although in color Maria Louise is the finest and best, the florists here say that it does not pay as well at $1 a hundred as Neapolitan at 50 cents. Cut flowers arranged in stands, dishes, and vases have also formed quite a feature of the exhibitions.

In fruits, a very fine display of winter pears was made by J. H. Fenno, who received prizes for Beurre Langelier, Easter Beurre, and Josephine de Malines. The first prize for Winter Nelis was given to J. L. Bird, and the second to J. H. Fenno, for Uvedales St. Germain; and the second prize to C. E. Grant for Catillac. Charles Bird exhibited an extra fine dish of Beurre d' Anjou. James Comley has shown some very fine forced rhubarb; the variety was Prince of Wales, and it was grown in a mushroom house.

The Society has appropriated for the present year $6,800 for premiums, divided as follows: For plants and flowers, $3,200; for fruits, $2,100; for vegetables, $1,200; for gardens and greenhouses, $300.
