Mr. Charles Wilkinson read a paper, ‘‘ Notes on some experiments, 
referring to the theory of the formation of gold nuggets in drift.” 
Mr. J. Bonwick rather questioned the novelty of the theory 
having heard Mr. Evan Hopkins, in 1852, put forth the same idea. 
Mr. Ulrich approved of the paper. Professor M‘Coy went minutely 
into the question, considering the analysis of the mine waters as avery 
important matter, and gave credit to Mr. Wilkinson for the paper 
just read. Mr. Aplin differed from the theory, seeing a physical 
difficulty inthe way. Mr. Wilkinson, after some discussion, replied 
generally to the objections. 
Mr. H. A. Thompson read a paper, ‘‘ Notes on the Extraction of 
Gold.” 
Professor M‘Coy, Messrs. A. K. Smith, and other members took 
part in a long conversation that ensued, and ultimately it was moved 
by Mr. A. K. Smith, seconded by Mr. Crooke, and carried, ‘“ That 
“the further discussion of Mr. Thompson’s paper be adjourned until 
“the next night of meeting.”
