 Throughout, the geology of the districts visited is described. A 

 treatise on " Sulphur in Iceland " forms an Appendix, vol. ii. pp. 328- 

 404, in 8 sections : — 1. Account of 0. Henschel's Eeport on the Ice- 

 landic Sulphur Mines (1776) ; 2. Sir G. S. Mackenzie's account of the 

 Krisuvik diggings (1812) ; 3. Extract from Consul Crowe's Eeport on 

 the mineral resources of Iceland (1871-72) ; 4. Letter on Mr. Vincent's 

 paper on the subject (1873) ; 5. Eeprint of a paper by Dr. C. C. Blake 

 on Sulphur in Iceland (1873) ; 6. Sulphur in Sicily ; 7. Suljjhur in 

 Transylvania; 8. Sulphur in the Andaman Islands, from Dr. Mouat's 

 book (1863). The author's researches respecting sulphur in Iceland 

 are scattered through the work. G. A. L.

Consists of 7 memoirs brought together for the consideration of the 

 Geographical Congress in 1875. 1 and 2 are geographical ; 3 describes 

 the system on which the drawing up of the detailed geological map of 

 France is carried out; 4 gives the history of that survey, with a 

 reduction of the table of divisions adopted by its directors ; 5 consists 

 of the detailed scheme of signs, colours, &c. used ; 6 is on the appli- 

 cation of 5 ; 7 urges a more strict uniformity in geological investiga- 

 tions, and the desirability of the union of geological, hydrological, and 

 meteorological studies. A table showing the position which the various 

 departments of geology should occupy in a general classification of the 

 sciences is given. The whole refers to Erench geology. G. A. L.
