In reference to the opposing views as to whether familiar geognostic relations of certain species are dependent upon the physical conditions or the chemical composition of the soil, Dr. Hoffmann states his opinion, based upon special investigations which he has instituted in the neighbourhoods of Giessen and Kissingen, that in the case of the so-called chalk-plants, the presence of a certain proportion of lime has the first influence. Close inquiry into apparently exceptional cases, and analysis of the soil, the author finds to confirm his view. When a "chalk-plant" is found isolated, on sandstone, for example, the number of individuals does not increase, nor does the plant thrive, and its existence is but transitory. Dr. Hoffmann shows, upon small maps of the vicinity of Giessen and Kissingen, having the alluvium, and the basaltic and calcareous formations shaded in, the localities of Prunella grandiflora and Dianthus carthusianorum. The basalt near Giessen contains from 7 to 12 per cent, of lime.
