interesting and timely contribution. Tiiese contributions are of 

 special interest to Canadian geologists and palaeontologists.

 Post Ordovician trap dikes in the Adirondacks." (Reprint)

 This very interesting contribution follows up the good work 

 done by Prof J. F. Kemp in the classification of the rocks of the 

 Eastern Adirondacks. In the "Rep. N. Y. State Geol. for 1893,, 

 Vol. I. p. 144 " Prof Kemp gave the various series of rocks met 

 within that region. In Prof Cushing's paper a new series is 

 described and added to the already known and described 

 Archaean series.

Contains a summary of the field work of British geologists in England and Wales, 

 Scotland and Ireland. 



England and Walfs. — The progress made in mapping out England and 

 Wales under their respective formations and systems is given from the Pre-Cambrian to 

 the Port Tertiary, including work performed by Messrs. Howell, Forbes, Strangways, 

 Watts, Bonney, E. Hill, Lamplugh, Strahan, Dakyns, Ussher, Gibson, De Ranee, 

 Gunn, Jukes- Browne, Cameron, Clement Reid, comprising most of the staff of field 

 geologist. Appended, there is a list of papers and memoirs published by members of 

 the Geol. Surv. of England and Wales during the year. 



Scotland.— Messrs. Howell (Director), Home, Peach, Clough, Harker, 

 Kynaston, Hugh Miller, Gunn, Grant, Wilson, Symes, Wilkinson, Hill, Barrow, 

 Hinxman, McConnochie comprised the staff of field geologists for Scotland in 1895- 



Mr. Teall has been acting Palaeontologist and determined the fossils obtained 

 by the collectors as heretofore. Mr. Teall has continued his investigations of the 

 Lewisian, Torridonian and later rocks of the N. W. Highlands. 



The Geological Survey collections are in charge of Mr. Goodchild in the 

 Museum of Science and Art, Edinburgh. 



Constant enquiries are made at the Geological Survey Headquarters for infor- 

 mation on the distribution of minerals in different parts of the United Kingdom. 



Mr. Teall's subdivisions of the "Lewisian gneiss" are worthy of note and 

 indicate the five groups into which the various masses are referable in the so-called 

 "fundamental complex." His scheme of classification will be found on page 18 of 

 the "annual report." 



Mr. Peach's excellent work is then described in detail regarding the 

 Lewisian, Torridonian and Cambrian areas. The progress made in mapping the 

 geological formations of Scotland are then given, from the oldest rocks, upwards.
