that the same genera of vertebrata are found in the Keuper and 

 Ehaetic beds, though the species, with few exceptions, are quite 

 distinct. 



But it is with the Lias that the name of Charles Moore is most 

 intimately associated. Time does not permit me to do more than 

 allude to the wonderful collections of Ehgetic and Liassic fossils 

 made by him from the fissure-veins of the Carboniferous Limestone, 

 or of the treasures which are stored in the Bath Museum. There 

 never was a more enthusiastic palgeontologist, and nothing pleased 

 him better than to exhibit the fossilized stomach of an Ichthyosaurus, 

 stained by the ink-bag of the cuttle-fish, on which it had been 

 feeding, or some similar palseontological curiosity. Everyone here 

 knows how deeply the West of England is indebted to Charles 

 Moore for his unceasing researches, and I have been thus particular 

 in alluding to them because it was under his auspices that I first 

 became acquainted with the geology of this part of the country just 

 thirty years ago. 



Amongst more recent work in the Eheetic and Lias I might 

 mention papers by Mr. H. B. Woodward and Mr. Beeby Thompson, 

 each in explanation of the arborescent figures in the Cotham Marble. 

 The latter revives an old idea with modifications, and his theory 

 certainly seems plausible. Mr. H. B. Woodward's Memoir of 1893 

 does full justice to the Lias of this district, and much original matter 

 is introduced. 



It is, however, in the Inferior Oolite that the most important 

 interpretations have to be recorded since the days when Dr. Wright 

 and Professor J. Buckman endeavoured to correlate the development 

 of the series in the Cotteswolds with that in Dorset. To this subject 

 I alluded at considerable length in my address to the Geological 

 Society in 1893, pointing out how much we owed in recent years to 

 the late Mr. Witchell and to Mr. S. S. Buckman. In the following 

 year appeared Mr. H. B. Woodward's Memoir on the Lower Oolitic 

 Eocks of England ("Jurassic Eocks of Britain," vol. iv), wherein 

 he did full justice to the work of previous observers. Meantime 

 Mr. Buckman has not been idle, and his paper on the Bajocian of the 

 Sherborne district ^ marks the commencement of a new era, where 

 the importance of minute chronological subdivisions, based upon the 

 prevailing ammonites, is insisted on with much emphasis. This 

 system he considers to be almost as true for the Inferior Oolite as 

 for the Lias. 



There can be no doubt that its application has enabled 

 Mr. Buckman to effect satisfactory correlations between the very 

 different deposits of the Cotteswolds and those of Dorset and 

 Somerset. In subsequent papers also he brings out an important 

 physical feature, viz., the amount of contemporaneous denudation 

 which has affected deposits of Inferior Oolite age in this country. 

 This serves in part to explain the absence of well-known beds in 

 certain areas. Eor instance, in the Cotteswolds contemporaneous
