SOMETIMES IT SEEMS AS IF everyone's immigrating to America – sailing-ships on the North Atlantic as thick as watermen's boats on the Thames, more or less wearing ruts in the sea-lanes – and so, in an idle way, Enoch supposes that his appearance on the threshold of the Massachusetts Bay Colony Institute of Technologickal Arts will come as no surprise at all to its founder. But Daniel Waterhouse nearly swallows his teeth when Enoch walks through the door, and it's not just because the hem of Enoch's cloak knocks over a great teetering stack of cards. For a moment Enoch's afraid that some sort of apoplectic climax is in progress, and that Dr. Waterhouse's final contribution to the Royal Society, after nearly a lifetime of service, will be a traumatically deranged cardiac muscle, pickled in spirits of wine in a crystal jug. The Doctor spends the first minute of their interview frozen halfway between sitting and standing, with his mouth open and his left hand on his breastbone. This might be the beginnings of a courteous bow, or a hasty maneuver to conceal, beneath his coat, a shirt so work-stained as to cast aspersions on his young wife's diligence. Or perhaps it's a philosophick enquiry, viz. checking his own pulse – if so, it's good news, because Sir John Floyer just invented the practice, and if Daniel Waterhouse knows of it, it means he's been keeping up with the latest work out of London.
