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.
_December_ 25, 1849 .-- Nawabgunge, eleven miles.

The soil good, as indicated by the growth of fine trees on each side of the road as far as we could see over the level plain, and by the few fields of corn in sight; but the cultivation is deficient and slovenly.
