“Oh! infinitly omnipotent God whose mercyes are fathomlesse, and whose knowledge is immense and inexhaustible next to my Creation and Redemption I render thee most humble thanks even from the very bottome of my heart and bowells, for thy voutchchafeing me (the meanest in understanding), an insight in soe great a secret of nature beneficial to all mankind as this my Water-commanding Engine. Suffer me not to be puff’d upp, O Lord, by the knowing of it, and many more rare and unheard off, yea unparaleled Inventions, Tryals, and Experiments, but humble my haughty heart, by the true knowledge of myne owne ignorant, weak, and unworthy nature, proane to all euill O most mercifull Father my creator, most compassionatting Sonne my Redeemer, and Holyest of Spiritts, the sanctifier, three diuine persons and one God! grant me a further concurring grace with fortitude to take hould of thy goodnesse, to the end that whatever I doe, unanimously and courageously to serue my King and Countrey, to disabuse, rectifie, and convert my vndeserved yet wilfully incredulous[P] enemyes, to reimburse thankfully my creditors, to reimmunerate my benefactors, to reinhearten my distressed family, and with complacence to gratifie my suffering and confiding friends may, voyde of vanity or selfe ends, only be directed to thy honour and glory euerlastingly. Amen.” With Caspar Kaltoff to superintend the work at Vauxhall, the engine would no doubt be kept in operation, for the benefit alike of the Dowager Marchioness and all interested, most likely including Colonel C. Copley. In the travels of Cosmo de Medici the Third, Grand Duke of Tuscany,[30] through England,[Q] among other matters that attracted his attention in the metropolis, it is recorded that on the 23rd of May, 1669:--“His Highness went to see an hydraulic machine upon a wooden tower, in the neighbourhood of Somerset House,[R] which is used for conveying water of the river to the greater part of the City. It is put in motion by two horses, which are continually going round, it not being possible that it should receive its movement from the current of the river, as in many other places where the rivers never vary in their course; but this is not the case with the Thames, owing to the tide; consequently the wheels, which serve at the ebb, would not be able to do their office when the tide returns.” On the 29th following, his Highness was entertained by the Earl of Devonshire, when a sumptuous banquet was provided.
