[Note 1: The farmyard dung was burnt slowly in a heap in the open
air to an imperfect or coaly ash, and 32 cwts. of ash represent 14
tons of dung.]

[Note 2: The silicate of potass was manufactured at a glass-house,
by fusing equal parts of pearl-ash and sand. The product was a
transparent glass, slightly deliquescent in the air, which was ground
to a powder under edge-stones.]

[Note 3: The manures termed superphosphate of lime, phosphate of
potass, phosphate of soda, and phosphate of magnesia, were made by
acting upon bone-ash by means of sulphuric acid in the first instance,
and in the case-of the alkali salts and the magnesian one neutralizing
the compound thus obtained by means of cheap preparations of the
respective bases. For the superphosphate of lime, the proportions were
5 parts bone-ash, 3 parts water, and 3 parts sulphuric acid of sp. gr.
1.84; and for the phosphates of potass, soda, and magnesia, they were
4 parts bone-ash, water as needed, 3 parts sulphuric acid of sp. gr.
1.84, and equivalent amounts, respectively
