 The nature of the habitats, and the special locality of rarer species, 

 are given, also the vulgar name of each species ; if only generic, 

 the Latin adjective is translated.

In reference to the opposing views as to whether familiar geo- 

 gnostic 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 in- 

 stituted in the neighbourhoods of Giessen and Kissingen, that in 

 the case of the so-called chalk-plants, the presence of a certain pro- 

 portion of lime has the first influence. Close inquiry into apparently 

 exceptional cases, and analysis of the soil, the author finds to con- 

 firm his view. When a " chalk-plant" is found isolated, on sand- 

 stone, for example, the number of individuals does not increase, nor 

 does the plant thrive, and its existence is but transitory. Dr. Hoff- 

 mann shows, upon small maps of the vicinity of Giessen and Kissin- 

 gen, having the alluvium, and the basaltic and calcareous formations 

 shaded in, the localities of Prunella grandiflora and Lianthus ear- 

 thusianorum. The basalt near Giessen contains from 7 to 12 per cent, 

 of lime.
