Pressing as were his personal necessities, he continued untiring in maintaining the practical working of the new engine set up under protection of the Act he had obtained in 1663. But, like all novel enterprises, people were sceptical as to its real value. He appears to have been wholly neglected by the first scientific authorities of his day, who yet could not be otherwise than aware of the remarkable performance of the engine erected by him at Vauxhall. We find him making sufficient allusion to its nature and properties in his _Century_, published in 1663; then, in 1664, Sorbière published his account of his visit to England, further describing what he had seen of the water-works at Vauxhall; while Dr. Sprat, by the severe strictures he wrote on the Royal-Hydrographer’s book, in the letter he published, addressed to Dr. Wren, at Oxford, must have spread the intelligence, and served to call attention to Sorbière’s statement.
