The following writers have offered the best examples of this mode ofclassification: —
Jon. Osborne, M.D. On the Indications afforded by the Sensible Qualities of Plantswith respect to their medical Properties. Contained in the Transactions of the Asso-ciation of Fellows and Licentiates of the King- and Queen’s College of Physicians,vol. v. 1828. ... •

b. Classifications founded on natural-historical properties. —By natural-historical properties, I mean those made use of in natural history.They are principally external form and structure. In living beings wefind that peculiar structure denominated organized. The structure calledcrystalline is peculiar to mineral and other inorganized bodies.
A. Classifications of organized beings. —In the fol 1 owing works thevegetable substances employed in medicine are arranged according totheir natural-historical properties

As in the subsequent part of this work the vegetable and animal sub-stances used in medicines will be arranged in natural-historical order, itwill be unnecessary here to offer any examples illustrative of it. I havepreferred this mode of arrangement principally on account of the greatdifficulties attending any other method, especially that founded on theeffects of medicines.
Artificial method of Linneus. —This appears to me the best place fornoticing those pharmacological works in which the Linnean artificialmethod of arranging plants is followed.
