and ' syenitic ' rocks of medium and fine texture. The central 

 block of the range, from the Wych to the fault in Swinyard's Hill, 

 consists chiefly of the lower and upper middle series, but with a 

 portion of the lower series at the south end. The upper series 

 consists of mica-schist and finely crystalline gneiss. He had little 

 doubt that the fine-grained schists were sedimentary, as they even 

 contained beds of quartzite. He further discusses how far the 

 foliation of these rocks and their main divisional planes represent 

 original stratification, leaving this point an open question. He 

 observes that, in the Malverns, the strike of foliation is not parallel 

 to the axis of elevation. Although Mr. Hutley was inclined to 

 believe that the divisional planes may be planes of original stratifi- 

 cation, he cannot say more than that they are original planes of 

 some sort, between which the rocks exhibit diverse lithological 

 characters. 



In the second portion of his paper this Author gave the results of 

 the microscopic examination of these rocks, which tended to show 

 that those of a truly eruptive origin are more plentiful in the range 

 than he at first supposed. He admitted there was no reason to 

 believe that the alteration of any ordinary sedimentary rocks could 

 have resulted in such a vast amount of hornblende as is found in 

 these gneisses, and he suggested a pyroclastic origin for some of the 

 beds. It is evident that he could not free himself from the idea 

 that some at least of the structural planes in these rocks indicate 

 planes of stratification; and that the foliation, in many cases if not 

 in all, denotes lamination due to deposition, either in water or on 

 land-surfaces, possibly accentuated by subsequent movements. We 

 plainly perceive that Mr. Eutley, at that time, regarded the main 

 mass as consisting of ordinary sediments metamorphosed into schists 

 and intruded upon after their formation by igneous masses. Although 

 he could not exactly make out the relations of foliation to sedimen- 

 tation, he felt sure that there had been deposition of some sort. 

 Nor has he very much altered that position in more recent years. 

 Speaking, for instance, when Dr. Callaway's second paper was read, 

 he allowed that a certain number of rocks were eruptive, although 

 he considered that a large portion consisted of the detritus of erup- 

 tive rocks, while towards the south they were mainly micaceous 

 schists and bedded quartzites, which he regarded as altered sedi- 

 mentaries. When Dr. Callaway's third paper was read, Mr. Eutley 

 went so far as to allow that the schists of the Malvern Hills had 

 been formed, to some extent, from plutonic rocks. This we must
