decanting the clear caustic liquor, evaporating in a silver crucible,
re-dissolving in alcohol, and then distilling the spirit, and heating
the residual pure soda to redness. Even in this state, soda contains 23
per cent of water, and only 77 per cent of _pure anhydrous soda_.

"Ten grains of this soda were dissolved in 1000 grains of distilled
water. But as 10 grains of this soda contained only 7.7 grains of
_anhydrous soda_, the 1000 grains of water would contain just 0.770 per
cent of soda--a quantity that differs very little from that contained in
the saturated aqueous solution of borax.

"Seven measures of the soda solution were added to four measures of
linseed oil. This mixture differed so little in appearance, that it
might have been mistaken by any casual observer as identical with that
produced by a similar proportion of the solution of borax. It had,
however, a more soapy odour; and a considerable separation of its
constituent parts occurred almost immediately after agitation. This
separation increased for many days. The lower liquid was of a foxy brown
colour, and, after a week's repose, it amounted to 38 parts out of 59.
The upper 21 parts were white and saponaceous. I tried other proportions
of soda solutions with oil, but none resembled the results obtained from
solutions of borax with oil.

"Fancying that solutions of the bi-carbonate of soda might be more
analogous to those of the bi-borate of soda in their effects upon oil,
than solutions of caustic soda, I tried many mixtures of solutions of
the bi-carbonate with oil; but they were all dissimilar, in appearance,
odour, and properties, from like mixtures prepared with the bi-borate of
soda."--_Letter from C. Thornton Coathupe, Esq., on Vehicles for
Pigments. Published in the Art Union of February_ 1832.]

the Commissioners of the Income-tax as those we have quoted, as a
consequence of our forced and hot-bed encouragement, remains to be seen.

ferment of patronage shall again have settled down to a selection of a
few favourites, may we not entertain somewhat similar fears?]
