Note 216 — I.—PHÆNOGAMOUS OR FLOWERING PLANTS. (continued 2)
Reading edition
Information kindly given us (9th June, 1873) by Mr. W. Dillworth Howard, of the firm of Howard and Sons, Stratford. A morphine manufacturer has no particular interest in ascertaining the amount of water in the opium he purchases. All he requires to know is the percentage of morphine which the drug contains. It is otherwise with the pharmaceutist, whose preparations have to be made with dried opium.
