It will be observed that the correspondence between the 
two analyses is very striking, and also that in a general way, 
these lake ores resemble our ordinary bog ores in composi- 
tion. Judging from published analyses, however, the 
average proportion of volatile matter in the latter is higher 
than in the lake ores. The average quantity of water, 
deduced from nine analyses of Canadian bog ores, is 19.78 
per cent., while the average deduced from seven analyses of 
Swedish lake ores by Svanberg, is only 14.13 per cent. (**)
