[478] The well-known Sir John Hill, an Englishman, has proved, however,
in later times, the possibility of injecting a substance into the
vessels of plants also. He dissolved sugar of lead in water, suspended
in it bits of the finest wood, so that one-half of them was under water
and the other above it, and covered the vessel in which they were
placed with an inverted glass. At the end of two days he took the bits
of wood out, cut off the parts which had been immersed in the water,
dipped them in a warm lye made of unslaked lime and orpiment, like
what was used formerly for proving wine; and by these means the finest
vessels, which had been before filled with sugar of lead, acquired
a dark colour, and their apertures became much more distinct. This
process he describes himself in his work on the Construction of Timber.
