 extensive bibliography of the less scientific and more descriptive treatises on the 

 West Indies.) 



At the Bath meeting of the British Association for the Advance- 

 ment of Science in 1888 I presented numerous rock specimens and 

 thin sections cut from them, illustrating a region of about forty miles 

 around Santiago de Cuba. The rocks were partly eruptives and partly 

 classic, but almost all exhibited profound alteration. The thin sec- 

 tions from these eruptives were examined with me by Dr. Hensoldt, 

 Mr. Kunz and Mr. La Croix in this country, and later by Mr. Teall, 

 Mr. Rudler, the Abbe Renard, Prof. Judd and the lamented Prof. 

 George H. Williams in London; all of whom were practically agreed 

 as to the main constituents. 



The specimens were divided into : 



A. Those from the hills containing the West mine of the Jurugua 



^ A more detailed statement of the observations, in the field and with the mi- 

 croscope, on which these conclusions are based will be published later. — P. F.
