Doctor O’Shaughnessy further states, that the reha earth, which I sent to him from Oude, is identical with the sujjee muttee of Bengal, and contains carbonate of soda and sulphate of soda as its essential characteristic ingredients, with silicious clay and oxide of iron.  But in Oude, the term “sujjee” is given to the carbonate and sulphate of soda which remains after the silex has been removed from the reha.  The reha is fused into glass after the carbonic acid and moisture have been expelled by heat, and the sujjee is formed into soap, by the addition of lime, fat, and linseed oil, in the following proportions, I am told:—­6 sujjee, 4 lime, 21/2 fat, and 11/2 ulsee oil.

The sujjee is formed from the reha by filtration.  A tank is formed on a terrace of cement.  In a hole at one corner is a small tube.  Rows of bricks are put down from one end to the other, with intervals between for the liquor to flow through to the tube.  On these rows a layer of stout reeds is first placed, and over them another layer composed of the leaves of these reeds.  On this bed the coarse reha earth is placed without being refined by the process described in the text above.  Some coarse common salt (kharee nimuck) is mixed up with the reha.  The tank is then filled with water, which filters slowly through the earth and passes out through the tube into pans, whence it is taken to another tank upon a wider terrace of cement, where it evaporates and leaves the sujjee deposited.  The second tank is commonly made close under the first, and the liquor flows into it through the tube, rendering pans unnecessary.  It is only in the hot months of March, April, May, and part of June, till the rains begin to fall, that the reha and sujjee are formed.  During the other nine months, the Looneas, who provide them, turn their hands to something else.  The reha, deprived of its carbonic acid and moisture by heat, is fused into glass.  Deprived of silex by this process of filtration, it is formed into sujjee, from which the soap is made.

On this process of filtration.  Doctor O’Shaughnessy observes:-"I do not clearly understand the use of the common salt, used in the extraction of soda, in the process you described.  But many of the empirical practices of the natives prove, on investigation, to square with the most scientific precepts.  For example, their proportions in the manufacture of corrosive sublimate are precisely identical with those which the atomic theory leads the European chemist to follow.  The filtering apparatus which you describe is really admirable, and I doubt much whether the best practical chemist could devise any simpler or cheaper way of arriving at the object in view.”

The country is well provided with mango and other fine trees, single, and in clusters and groves; but the tillage is slovenly and scanty, strongly indicative of want of security to life, property, and industry.  No symptom of the residence of gardeners and other cultivators of the better classes, or irrigation, or the use of manure in tillage.
