upheaval in New Guinea, especially as there has never been any 

 similar evidence found on the east side of the Australian conti- 

 nent. It remains to be seen whether, in this case as in the 

 Southern Australian tertiaries, we have the sign of volcanic 

 activity accompanying the upheaval. Mr. Macleay showed me 

 specimens of true amygdaloidal and vesicular dolerites, taken from 

 the coast of Darnley Island, opposite Yule Island, a distance 

 however of 150 miles. They were in all respects similar to the 

 Victorian pliocene dolerites. The bathymetrical evidence of these 

 fossils show that at least there has been upheaval to the extent of 

 400 or 500 feet.
