cent; while a portion of the water taken from the spring three 
weeks earlier gave a large proportion of alkalies, equal to 03400 
of chlorids; of which 0:0596, or 1753 per cent, were chlorid of 
potassium. 
2. This spring occurs on the bank of the Jacques Cartier river, 
a little above Quebec. It is strongly impregnated with sulphur- 
etted hydrogen, and appears to contain a considerable proportion 
of borates. It was collected for analysis in the summer of 1852. 
8. This water is from a spring in the township of Joly on the 
opposite side of the St. Lawrence, a few miles south from the last, 
and like it is sulphurous, and affords a strong reaction of boric 
acid. It was collected for analysis in July, 1853. 
4. A small area of marshy ground in the seigniory of Nicolet, 
near the line of St. Gregoire, is, like the similar tract in Chambl 
so impregnated with mineral water as to be destitute of vegeta- 
tion. The water collected in a small pit, dug in this locality in the 
autumn of 1853, was yellowish colored, and alkaline to the taste, 
and gave by analysis the above results. Several other alkaline 
springs occur in this vicinity. All of the preceding waters, with 
the exception of No. 2, which comes out from the Utica slates, 
rise, like that of Chambly, from the Hudson River formation. 
. This water, unlike the preceding, is that of a large river, 
the Ottawa, which drains a region occupied chiefly by ancient 
ine rocks, covered by extensive forests and marshes. .The 
the first five waters are for 1000 parts, while those of the Oused ot 
are for 10,000 parts.
