leevigatum. But the specimens distributed from Dr. Dewar, 

 through the Botanical Societies of London and Edinburgh, 

 and locahzed at ToiTie, Fife, do not correspond with the 

 L. laevigatum of the Linnean Herbarium ; nor, waiting from 

 recollection of the Clova plants, do I think that the very 

 few stray examples there seen would coiTespond much bet- 

 ter. I consider that the sinking of L. maculatum, by Mr. 

 Bentham, as a variety of L. album, if equally acted up to 

 in other cases, would lead to the suppression of thousands 

 of species generally so received; and that this course 

 would be fully as confusing and injurious to the progress 

 of real science (inductive and generalized science) as the 

 opposite fault of hastily .splitting species on account of tri- 

 fling differences, without previous experiment, or even, as 

 too often done, without careM and truth-seeking examina- 

 tion of a proper series of their individual forms. In avoid- 

 ing Scylla, Mr. Bentham sweeps headlong into Chaiybdis.

 cent separation of L. intermedium, as a species distinct 

 from this present one, it becomes doubtful under which of
