378 SECTIONAL TRANSACTIONS.—C. 
the previously published cases will be only very briefly mentioned. More time will 
then be devoted to fuller presentations of the facts concerning many similar conditions 
discovered since 1911 in the Appalachian region, the Ozark region of Missouri and 
Arkansas, the Arbuckle and Wichita uplifts in Oklahoma, and finally in the central ~ 
area of Texas.

Dr. L. J. Spenour, F.R.8.—Second Supplementary List of British Minerals. 
The first of these lists was presented at the Bristol meeting in 1898. They are 
intended to supplement the still standard work of Greg and Lettsom’s ‘ Mineralogy 
of Great Britain and Ireland’ (1858). The present list includes 90 names, of which 46 
(printed in italics) may be regarded as well-defined species with satisfactory records. 
This brings the total number of mineral-species that have,heen found in the British 
Isles up to 339, representing about one-third of the number of known species.
