and matrix, was as follows: — 1. Original rock (Marl?). 2. Meta- 

 raorphic change with crystallization of (a) Octahedrons of magnetite 

 and certain discoidal crystals ; (b) Garnets. 3. Pseudomorphic change. 

 Chlorite after the original rock and after garnet, but preserving the 

 magnetite and discoidal crystals intact. The plate gives 2 coloured 

 figures of microscopic sections of the rock. G. A. L.

 On pseudomorphous crystals of monticellite (lime-olivine), occurring 

 with anorthite at the Pesmeda Alp on the Monzoni ; on the twin forms 

 of the crystals of rhombic sulphur ; on calcite from the Ahrenthal, near 

 Brunneck, in Tyrol ; and on a twin of quartz with inclined axes from 

 Japan. An appendix gives observations on the optical characters of 

 the red mica of Yesuvius, and several analyses of lime-soda felspars.

In reply to Prof. Weisbach [p. 263], showing wherein the views of 

 Frenzel and Yom Rath differ from those of Breithaupt respecting the 

 crystals which exhibit regular growth of quartz and calcite, from 

 Schneeberg in Saxony. F. W. R.
