acid, 849 are contained in the neutral carbonates, leaving only 
‘141 towards the formation of bi-carbonates. For later analyses 
of these waters see § 46. 
. This, which is known as Gillan’s spring, is from the town- 
se of Fitzroy, not very far from the last. Its waters were 
collected in July, 1850. 
5, 6. These two waters are from Varennes, and are about one 
hundred rods apart. The first is known as the Saline, and the 
second is called the Gas spring from the large volumes of car- 
buretted hydrogen gas which it disengages. The Saline spring 
contained in 1000 parts ‘920 of carbonic acid, of which -451, or 
nearly one half, is required to form neutral carbonates present. 
In the-Gas spring was found -792 of carbonic acid, leaving thus 
812 over that required to form neutral carbonates. The waters 
were collected in October, 1848. 
7. This is from Labaie du Febvre, and is known as Cour- 
chéne’s spring. It evolves small quantities of carburetted hy- 
drogen gas. The water was collected in September, 1852. Sevy- 
eral other mineral springs occur in this vicinity, one of them 
belonging to this class, and others to the second and fourth 
classes.
