[Footnote 1: A gentleman told the writer that this was vulgarly called by the sobriquet of "Punch's Tuning Fork!"] Fitz Stephen (William) a learned Monk of Canterbury, being attached to the Service of Archbishop Becket was present at the time of his murder. In the year 1174 he wrote in Latin the life of St. Thomas, Archbishop and Martyr, in which as Becket was a native of the Metropolis, he introduces a description of the City of London with a miscellaneous detail of the manners and usages of the Citizens; this is deservedly considered a great curiosity, being the earliest professed account of London extant. He describes the springs and water courses which abound in the vicinity of Old London as "sweet, salubrious, and clear," so that all that the inhabitants and water-carriers had to do was to draw water from the wells and springs, or dip their vessels in the pellucid stream of the river which was fit for culinary and all ordinary and domestic purposes. London then though considered a "Great City" was as a small town when compared with its teeming population of nearly 5,000,000 which people its City and environs now.[1] Since that time the Majestic Thames and its tributary streams have been so polluted with sewerage and other deleterious and poisonous matter as to induce some of the most scientific men of the age to consider not only the desirability but the necessity of obtaining for London a pure water supply. It is asserted as a fact that in England and Wales alone upwards of eight hundred persons die every month from typhoid fever; a disease which is now believed to be caused almost entirely through drinking impure water, and Dr. Frankland, the official to whom is entrusted the analysing of such matters reports "The Thames Water" notwithstanding the care that is taken to filter it by certain Water Companies is so much polluted by organic matters as to be quite unfit for dietetic purposes.
