The analyses given by Mr. J. D. Kendallt of lava and ash- 
rock of the Borrowdale series are not new analyses but averages 
deduced from the above, viz., from (1) and (2) and from (3) and (4), 
respectively. Mr. P. F. Kendall,t in describing a large boulder 
found at Manchester, and probably derived from the Lake 
District, gives an analysis of it by Dr. J. B. Cohen, and for 
comparison one of a rock from ‘near Coniston,’ the locality no 
being more closely specified. The silica-percentages are :—
