time to time a few bubbles of carburetted hydrogen are evolved. 
he flow of water from the spring is probably two or three gal- 
lons per minute; around the well, there is a slight deposit, ochre 
yellow on the surface and bluish green within, and the course o 
the spring is tinged of a yellowish hue for some distance. The 
water is saline to the taste, and has a very agreeable flavor. _ 
above. The discharge is apparently about the same as that of 
the other spring; the water is saline to the taste and closely re- 
sembles that of the one before mentioned. 
he temperature of the two springs is somewhat different; on 
the 18th of October, that of the outer well was 47°°5 F., and that 
of the inner one 45°:5; the air being at the same time 44°. I 
had before visited these springs on the 20th of November 1847, 
| and found the temperature of the outer one nearly the same as 
° above stated, 47° F'., while the inner spring was 40°; the air be- 
ing 19°. I was informed by the proprietor that the former spring, 
although not protected from the weather, never freezes to any 
extent, while the latter, althongh sheltered by the house, and so 
much below the surface, is filled with ice in severe weather. The 
escape of such a quantity of gas, which may be supposed to find 
its way into the spring below in a greatly condensed state, and 
be rarified in rising, may help to explain in part this difference = 
but it is conceived by the villagers that it is affected by the changes 
of the seasons, and is at the same time warmer in summer, a 
fact which I have, however, not yet been able to verify by ex- 
periment. .

I. The Outer Spring.—This water has been already deseribed 
aS quite saline to the taste, and analysis shows the presence of 
large quantity of common salt, with traces of a salt of potassium. 
he concentrated water is distinctly alkaline, from the presence 
of a small quantity of carbonate of soda; the lime and magne- 
sia which are present are also held in solution as carbonates. In 
addition to these were obtained small quantities of bromine and 
lodine combined with the alkaline bases; traces of iron, alumina 
and silica, and the rare bases, baryta and strontia, which have 
never to my knowledge hitherto been observed in any of the 
mineral waters of this continent. The specific. gravity of the 
Water at 60° F., was determined to be 1008°15, pure water
