near the marble, and assumes a bottle-green colour, traces 

 of limestone being common in it ; whilst, on the other hand, 

 the marble near the greenstone is also changed^ so that a 

 passage may be traced from one to the other. The author 

 concludes by referring to other instances in New South 

 Wales, in which similar phenomena have been produced. 

 He mentions one case in lat. 32° 6' S., and long, about 151° 

 E., where, in the neighbourhood of the river Page, veins of 

 marble intersect a lava-like trap ; and another about 16 

 miles north of Arthursleigh, where a magnificent tunnel, in 

 white crystalline marble, occurs in the bed of a tjreek sur- 

 rounded by basaltic rocks. On a branch of the Abercrombie 

 river, west of the Dividing Range, and about 40 miles south 

 of Bathurst, a similar tunnel of gigantic dimensions, nearly 

 800 feet long, and 80 feet high, also passes through a mass 

 of white crystalline marble, at the bottom of a ravine in the 

 middle of a country of volcanic rocks, and blocks of snow- 

 white quartz. 



The author hopes to be able, at a future time, to describe 

 these examples more fully. He alludes to them now to shew, 

 that there is reason to believe that these connections of 

 limestone, plutonic rocks, and quartz dykes, are not without 

 their application to a condition of geological phenomena, to 

 the elucidation of which the banks of the Wollondilly have 

 exhibited a clue. — Proceedings of the Geological Society,

1. Particulars of the Fall of Meteorites in the Sandwich Islands. 

 Communicated, by request^ by the Rev. Hiram, Bingham, Mission- 

 ary in those islands, in a letter, dated Boston, May 1. 1845. 



To Professor Silliman. — On the 27th of September 1825, a 

 shower of meteoric stones fell, partly in the channel between Molo- 

 kai and Lanai, and partly between those islands and Oahu, and 

 partly at Honolulu, where I then resided. One explosion was heard 

 at Lahaina, and several in quick succession at Honolulu, eighty miles 

 to the north-west, between the hours of ten and eleven, a.m. The
