"It will flourish, if naturalists, chemists, antiquaries, philologers, and men of science in different parts of Asia, will commit their observations to writing, and send them to the Asiatic Society at Calcutta. It will languish, if such communications shall be long intermitted; and it will die away, if they shall entirely cease. SIR WM. JONES. CALCUTTA : PRINTED BY C. B. LEWIS, BAPTIST MISSION PRESS. 1868.

EXPERIMENTAL INVESTIGATIONS connected with the supply of WATER from the Hooghly to CALCUTTA, Part II, being Supplementary Observations; by DAVID WALDIE, Esq. F. C. S. &c. [Received 28th September, 1866.] In the preceding remarks I have directed attention to the discrepancies between my own results as to the quantity of organic matter by weight in the Hooghly water and those given in Dr. Macnamara's Report, and I have also made some pointed observations on the very doubtful accuracy and unsatisfactory nature of the results generally given by chemists respecting organic matter in waters, except some of the most recent. For though I have found that the process detailed in the previous part of my paper is older than I then supposed, having been recommended by Mr. Dugald Campbell in 1856 as suggested by Dr. Clark, and that an analogous plan was given by Abel and Bloxam in 1854,† though imperfect, yet these plans seem either to have been little known, or neglected, or imperfectly carried out. Some analysts indeed of later date do not even attempt to estimate the amount of organic matter at all, apparently despairing of reliable results. But the process given, I believe, yields the most trustworthy results hitherto obtainable, if properly performed. * Journ. Chem. Soc. Vol. IX. 1856, p. 51. |
