HISTORY IN BOTANICAL STUDY. 109 treatise in which de Blegny advocated its use in 1682 describes Cinchona bark as "le Remede Anglais." In a recent important treatise on Cinchona its natural history is condensed into the statement that the tree was known to the Indians of Loja as Quina-quina, but that these Indians had no knowledge of the medicinal property of its bark. We may admire the taciturn compression of this sentence and must admit that, for the first of its facts, its author has the unimpeachable authority of Condamine, who was in Loja in 1737; for the second, the equally unimpeachable testimony of Humboldt, who was in Loja in 1799. But we remember that Markham, whose evidence is as reliable as that of Condamine and that of Humboldt, has pointed out that in the Quichua Indian tongue reduplicated names usually indicate the belief that the things so named possess medicinal properties. The statement as it stands, therefore, includes two mutually contradictory assertions and their uncritical combination in one assertive sentence affords a striking example of neglect by the naturalist to give the attention they deserve to the methods of the Civil Historian. The atten- tion of the naturalist has recently been called to this question by Mr. Ramsbottom, who has furnished evidence that the name reported by Condamine certainly was applied by the Quichua- speaking Indians to a tree which they valued because of its medicinal properties. But it seems probable that the tree to which the name Quina-quina was primarily applied is the one which yields the Balsam of Peru; from this the historian is disposed to conclude that by 1737, when Condamine was in Loja, Spanish interest in Cinchona had enabled the Quichua- speaking Indians to supply us with an interesting example of the well-known phenomenon of name-transfer. If we see from what has been said how necessary it is to adopt the methods of Civil History when we wish to learn how Cinchona came to be used by European apothecaries and physicians, and how the name it bears arose, we find it just as necessary to employ these methods if we wish to understand the development of the commercial activity to which the discovery gave rise. The systematic botanist knows that the genus Cinchona is a very natural one, easily recognised and definitely restricted in distribution to the rain-forests of the inner Cordilleras, from
