These waters were bright and pure, and entirely unexception- 
able in point of aeration and colour. Their usual temperature 
when taken up was from 50^ to 52^, showing that their sources 
are deep-seated, and that thev preserve the average temperature 
of the whole year. Their taste betrayed no organic taint, but 
evinced great purity, although they appeared rather flavourless 
and somewhat vapid to persons habituated to the use of hard 
waters. 
Well-icaters. — Wells sunk in deep sandy soils or in siliceous 
rocks generally furnish soft waters. The following analvses of 
two soft well-waters from Hampshire were lately made bv me :

The sample !No. 1 was taken from a well 35 feet deep, the 
soil being sand and siliceous rock. The sample Xo. 2 was taken 
Irom a well 73 feet deep, sunk at a considerable distance from 
all buildings, through beds of sand and siliceous ironstone. 
Both samples are good, wholesome, soft-drinking waters, and 
well suited for general household purposes.
