. British bee journal & bee-keepers adviser. Bees. April 7, 1887.] THE BRITISH BEE JOURNAL. 155 or volatile, oils, oil of wintergreen [Gaulthcria procumbent) is synonymous with the oils of partridge-berry, methylo- salicylio ether, and salicylate of oxide of methyl. This ' Oleum gaultherice' (Pharmacopoeia of United States) is procured from the leaves, or the whole plant of Gau'.theria procumbens, a herb common in North America, and known also by the names of ' box-berry,' ' chequer- berry,' ' partridge-berry,' ' mountain-tea,' and 'winter- green.' When diluted it is agreeably fragrant. When mixed with a dilute solution of potassa it solidifies to a crystalline mass (salicylate of methyl and potassa) from which the oil may be again separated by the addition of an acid. Salicylic acid may be obtained from this ' Oleum gaultherice' by acting upon it with a strong and and hot solution of potassa, and afterwards separating the acid as before. But the greater part, if not the whole, of the salicylic acid of commerce, is now obtained by Pro- fessor Kolbe's method, which consists in acting on sodium carbolate with carbonic acid. See ' Cooley's Gyclopicdia.' Oil of wintergreen, pure and simple, we do not advise you to give to bees in syrup. It is much better and safer to keep to the solution of salicylic acid as recom- mended in Mr. Cowan's Guide-Bool:, p. 151. 0. W.—Food for the present Season.—The candy made as you propose will do, but we should substitute pea-flour for ordinary wheat-flour. The best method of feeding for a busy man is the dry sugar plan. Cover a frame both sides with the thin board used for picture-books, leaving an inch space open at the top of one side. Fill the trough thus formed with Porto Eico sugar and use as a dummy. Crowd the bees so that they are in contact with the feeder, and place enamel cloth on top of the frames to condense moisture. Inquirer.—We have not advanced so far in our endeavours to unravel the mysteries of the physiology
