 Salt has a strong influence on plants, and causes the first division 

 into (1) maW<m^,= plants that flourish in soils containing sodic chloride, 

 (2) terrestrial^ = plants to which it is uncongenial ; these latter are 

 divided into calcicolous (those that flourish on lime soils), calcifugous 

 (those repelled by limestone), and indifferent (those that will grow on 

 any soil not containing salt). The chemical influence of the soil is far 

 more powerful than the physical, and the repulsive action of salt or 

 lime than the attractive. Potassium, magnesia, iron, silicon, &c. seem 

 to have no influence on the dispersion of plants, though some have a 

 strong physiological action. Clay has only a physical (mechanical) 

 influence. Lists of European species are given to illustrate soil-influ- 

 ence. E. B. T.

 maps of European States. Section 1. Physiographical geology, pp. 5— 

 21. 2. P€<rojr«^^imZ, including microscopical structure; rocks classified 

 as (a) simple, (6) mixed, (c) klastic. Further (6) is subdivided into : — 

 massive crystalline rocks, varieties given in detail, pp. 59-99 ; and 

 schistose, gneiss, phyllite, &c., pp. 100-107. 3. Dynamical geology : 

 vulcanicity, pp. 123-157; hotsprings, earthquakes, pp. 158-179 ; water- 

 action, chemical and mechanical, glaciation, &c., pp. 180-244 ; disinte- 

 gration by atmosphere, organic agents, &c., pp. 245-269. 4. Petro- 

 genetic : origin of rocks, eruptive, sedimentary, and metamorphic, pp. 

 270-311. 5. Architectonic, relative positions of rocks, dip, faults, 

 cleavage, mineral veins, &c., pp. 312-340. 6. Historical : introductory, 

 touches the transmutation theory, nebular hypothesis, &c., pp. 341-360 ; 

 Archaean to Kainozoic, pp. 361-678. The eruptive phenomena in each 

 formation have a separate paragraph. Tables of homotaxial beds in 

 different countries also under each formation ; and short lists of the 

 commoner fossils. E. B. T.
