    III. REPORT OF EXAMINATION AND ANALYSIS OF CERTAIN SAMPLES OF WATER FROM HASTINGS, BY DR. A. S. TAYLOR. The samples of water, well secured and sealed in Win- chester Quart bottles, were received at the Chemical La- boratory, Guy’s Hospital, on Feby. 1, 1859. The samples Samples, were seven in number, arranged in two groups, Nos, 1, 3, 5, and Nos. 2, 4, 6, 7. They were submitted to a qualitative examination for General the detection of the usual constituents of spring and river Properties, water. They were colourless, and without smell or taste, —for the most part clear and bright, depositing on stand- ^ ^po- ing but a small amount of sediment, chiefly of a silicious ^ or sandy nature. In all the samples, the same mineral quantity, constituents were found, namely sulphuric acid and lime, as sulphate of lime,—chlorine, representing common salt or chloride of sodium, carbonic acid and air. FIRST GKOUP. Samples 1, 3, 5. Of this group. No. 5 was remarkable for its compa- Samples rative purity or freedom from saline matter. It contained 1, 3, 5. a mere trace of sulphuric acid and lime, as sulphate of lime : the principal mineral ingredient in it, was chloride of sodium, or common salt. No. 1 gave rather stronger indications of the presence of sulphate of lime than No. 5 ; and after 48 hours, there was a visible deposit of the con- gt^tuents. stituents of this substance. The quantity of chlorine or chloride, appeared to be the same as in No. 5. Sample No. 3 contained the largest amount of saline matter of this group. There was a well-marked quantity of sulphate of lime, and a comparatively large proportion of common salt.
