APPENDIX. 
I place the two stones now to be mentioned in an appendix, 
because the evidence of their extra-terrestrial origin is not, in all 
respects, perfect. While there is much in the circumstances un-

which this depends; nor is this coe fully” counterbalanced 
by the nature of the stones themselves

covery. He observes that its finder was Capt. Josiah Crosby, of 
Waterville, that he is a good observer of natural phenomena, has 
paid edinsiderable attention to mineralogy, and that his character 
is beyond question. His statement is as follows
