granit', the ' Waiilsortian ', and the ' sublcevis oolite') have been 

 discovered at certain points of the South-Western Province, and they 

 are adumbrated at many others. [If, furthermore, we extend our 

 researches and compare the Midland and Northern developments of 

 England and Wales with that of Belgium, striking identities are 

 observed ; for example — 



The ' Brachiopod Beds ' of the Midlands and of Vise are identical. 

 The lower ' knolls ' of the Clitheroe area are typical ' Waulsortian '.] 



The following are the most important conclusions from the author's 

 work in Belgium : — 



(1) Phjsiographical Phenovie7ia. — The lateral variation of Mid- 

 Avonian lithology is strikingly exhibited in a diagram. Minute 

 correlation of the Belgian sequence with that of the South-Western 

 Province demonstrates that the periods of partial emergence, of the 

 west of the South-Western Province and of tlie east of the Belgian 

 Province, took place consecutively and not simultaneous!}', namely : 

 in the South-Western Province at the close of C^ time, in Belgium at 

 the beginning of Visean time. At the latter period England and 

 Wales, outside the South-Western Province, had sunk below the 

 Carboniferous sea. [Simultaneously, however, Ireland was, like 

 Belgium, under emergent conditions.] 



(2) Palceontological Phenomena. — The palseontological section contains 

 descriptions of several gentes that are common in Belgium, but rare 

 in Britain. The most interesting portion of the section is, however, 

 that which deals with the evolution of the important Carboniferous 

 corals and brachiopods. Two illustrations were selected, and were 

 shown as lantern-slides : —

2. Fragments of the history of Spiriferinaoctoplicata, showing variation

These facts concerning migration and evolution are, unquestionably, 

 the most important results of extending the area of observation. 



The author has received continuous and invaluable assistance from 

 Professor G. Delepine and from Mr. E. E. L. Dixon ; he is also very 

 deeply indebted to the recent works of Professor Delepine and Dr. A. 

 Carpentier (Northern France), from which he has cited freely.

Mr. E. T. Newton, in exhibiting a series of small mammalian and 

 other renuiins from the rock-shelter of La Columbiere, near Poncin 

 (Aiu), said that, during the year 1913, Dr. Lucien Mayet and 

 M. Jean Pissot were working systematically at the prolific deposits 

 of this locality, and towards the end of the year made known the
