Society and everyone else interested in minerals should feel indebted to 
Mr. Petterd for devoting so much time in affording valuable information 
on such an important subject. 
TESTING MINERAL SPRINGS. 
Major-General ToTTENHAM made some remarks on ‘‘The rough 
testing of mineral springs,” in which he said that in a country so rich in 
minerals as Tasmania there must be mineral springs, wells, and creeks 
in unusualnumbers. He suggested that yachtsmen and explorers might 
well invest a few shillings in a tiny case of tests, systematic search, 
collection of information, and chemical investigation of their medicinal 
and other commercial values. This was extremely desirable in further- 
ance of the Premier’s idea of placing Tasmania more prominently before 
the world. 
The general business having been transacted, the usual vote of 
thanks to writers of papers terminated the meeting.
