On the alleged conversion of crystalline schists into igneous rocks in County 



Gahvay. Qnai\ Jour. Geol. Soc, No. 171, August, 1888, vol. xliii, p. 517. 



Contends that the ancient gneisses of Galsvay (Ireland) display evidence of 

 having been formed in part from mixtures of diorite and granite, similar to the 

 more modern " diglomerates." 



The above-iiuoted author has also contended (same journal, p. 530) that many of 

 the gneissic and schistose rocks of the Malvern Hills are formed out of igneous 

 materials and owe their foliated structure to regional pressure, as proven by the 

 intense contortion of granitic veins and by the mechanical effects recognized in 

 the rocks uiuler the microscope.

The Gneissose Granite of the Himalayas. Geol. Mag., May, 1887, p. 212. 



Describes with some detail the macroscopic and microscopic structure of this 

 granite, and which he contends could not have assumed its marked gneissic struc- 

 ture through merely mechanical agencies. Regards it as produced by a forcing up 

 of a semi-plastic granite porphyry mass through faults in the overlying rock where 

 it was subjected to enormous pressure. Before final consolidation took place, 

 minor and subsidiary eruptions took place, which forced new supplies of granitic 

 material into fissures formed in the previously injected rocks, and this fresh mate- 

 rial consolidated under conditions somewhat different from those of the first 

 eruptions.

Has studied the effects of pressure on sedimentary aud massive rocks, and 

 shows how in conglomerates a schistose structure may be produced which is quite 

 distinct from the bedding due to sedimentation.
