of inestimable value, but also to geologists and others, who 
see in the remarkable " Sorbitic " structures disclosed close 
and highly suggestive analogies with the structure both of ter- 
restrial igneous rocks and still more with the structure of meteor- 
ites made known to us by Sorby's own researches. 
Sorby lived a life of strenuous scientific work, harassed 
fortunately by no cares, and upheld constantly by an eager 
and sanguine enthusiasm. To the younger generation of geolo- 
gists his example is full of inspiration, and no more profitable 
exercise could be commended than a careful perusal of his papers.
