B. Explanation of Plates. 



The Sketch Map, Plate IX., is intended to indicate roughly the general struc- 

 ture of the Harz, and to show the positions of most of the places referred to in 

 the text, and of the lines of Section in Plate X. The contemporaneous diabases 

 are shown, but the numerous patches of intrusive diabase, as well as the dykes 

 of quartz-porphyry, etc., have, to avoid needless complexity, been omitted. 



The Sections, Plate X., are drawn to the same scale as Lossen's Map. The 

 verticals are about double the horizontal distances. The sections do not pre- 

 tend to any great accuracy in detail, and are intended merely to serve as 

 illustrative diagrams approximately correct in general outline only.
