BRITISH ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE 

 22 ALBEMARLE STREET, LONDON, W. 



The next ANNUAL GENERAL MEETING will be held at MANCHESTER,

President- Elect,

Notice to Contributors of Memoirs. — Authors are reminded that, under an 

 arrangement dating from 1871, the acceptance of Memoirs, and the days on which 

 they are to be read, are now, as far as possible, determined by Organizing Commit- 

 tees for the several Sections before the beginning of the Meeting. It has therefore 

 become necessary, in order to give an opportunity to the Committees of doing 

 justice to the several Communications, that each Author should prepare 

 an Abstract of his Memoir, of a length suitable for insertion in the pub- 

 lished Transactions of the Association, and the Council request that he will send 

 it, together with the original Memoir, by book-post, on or before August 3, 

 addressed thus : — " General Secretaries, British Association, 22 Albemarle Street, 



London, W. For Section " Authors who comply with this request, 



and whose Papers are accepted, will be furnished before the Meeting with 

 printed copies of their Reports or Abstracts. If it should be inconvenient to 

 the Author that his Paper should be read on any particular days, he is requested 

 to send information thereof to the Secretaries in a separate note. 



Reports on the Progress of Science, and of Researches intrusted to Individuals 

 or Committees, must be forwarded to the Secretaries, for presentation to the 

 Organizing Committees, accompanied by a statement whether the Author will 

 be present at the Annual Meeting. 



No Report, Paper, or Abstract can be inserted in the Report of the Associa- 

 tion unless it is in the hands of the Secretary before the conclusion of the Meeting.

THE ORIGIN OF MOUNTAIN RANGES,

 and in relation to their GEOLOGICAL HISTORY. 



By T. MELLARD READE, C.E., F.G.S., E.R.I.B.A., 



Past President of the Liverpool Geological Society. 



Extracts from Reviews (up to April 7, 1887). 



" We very heartily recommend this valuable work to the attention of geologists, as 

 an important contribution to terrestrial dynamics."— Philosophical Magazine. 



" It is long since geological literature has been enriched by so able, so philosophical, 

 and so profound a work." — Knowledge. 



" The work marks a distinct advance, and is a valuable contribution to physical 

 geology, and must take its rank accordingly." — The Builder. 



"Nothing could be more suited to entice the student into further research than 

 so charmingly- written and clearly -reasoned a treatise." — Christian World. 



" Mr. Eeade's work is a valuable contribution to the perplexing subject of mountain- 

 making." — J. P. Pana ('American Journal of Science '). 



" The author has had the advantage of being his own artist, and has embellished the 

 volume with a wealth of illustration rarely to be found in scientific books." — Liverpool 

 Courier. 



" By his title he perhaps unconsciously courts comparison with Darwin's celebrated 

 ' Origin of Species,' and there is some analogy between them in the immense area of 

 fact and speculation covered by the subject in either case." — Liverpool Paily Post. 



" The book has two merits : it takes nothing for granted, and it does not err on the 

 side of assuming too much knowledge on the part of its readers." — Nature.
