2. This water is from a copious spring which issues from the | 
limestones of the Trenton group at Whitby, on the north shore a 
of Lake Ontario. It contained small portions of baryta and | 
strontia, and was collected in October, 1853. + 
4. Several wells have been sunk in the Trenton limestone — 
sought for the manufacture of salt, is now much used for medi- 
cinal purposes. Its strength seems subject to some variation, 
since a specimen from the same well in December, 1861, gave mé,4 
by a partial analysis, ehlorid of sodium 23°00, chlorid of calcium 
9°66, chlorid of magnesium 2-40, sulphate of lime 1-75=8681 
parts in 1000. No. 6, examined at the same time, is from a sec- 
er aor in 1861, not far from the last. 
0. nese are analyses of the waters from two borings in the _ 
Trenton limestone at Morton’s distillery in Kiniaion re the 
analyses are by Dr. Williamson ueen’s College in that city 
and were made probably ten or twelve years since. T ey have 
been recalculated so as to represent the whole of the sulphuric 
acid as combined with calcium. The first of these waters gave 
to Dr. Williamson both bromine and iodine, and the second was
