    so LANU AS A M DULCAM MEDICINAL PLANT. By JOHN HAELEY, M.D., Ac. The following is a contribution to the elucidation of a plant which still retains a place in the Pharmacopoeias of Great Britain, of France, of Germany, and of the United States. On the 26th August, 1867, Mr. Buckle, of Gray’s Inn Koad, expressed for me the juice of thirty-four pounds of fine plants grown in the northern outskirts of London. The plants were laden with green fruit, and were destitute of roots. The quantity of juice obtained was seventeen im- perial pints, weighing twenty-one pounds four ounces = 62‘5 per cent, by weight, or 50 by measure. Part of this juice was converted into “ Succus ” in the manner and proportions directed in the Pharmacopoeia for Succus Conii—but the pre- cipitated matters were not separated;—and part into “Extract” Ten pounds of the crude juice yielded fifteen ounces of extract. The evaporation was effected by steam heat, and the tempera- ture was not allowed to rise above 170° Fahr. On the 21st of September, 1869, I picked from sturdy trailing plants,1 which grow in the full exposure to the sun on the shingly beach between West Worthing and. Goring, in Sussex, forty-two ounces avoidupois of fine, ripe, mucilaginous, thin-skinned berries. They were pulpSd the same day and mixed in a stoppered bottle with proof spirit acidulated with CZ\ 1 Var. y marinum, Babingt^^ VOL. VI. 19
