“The greater sort which serve to hunt, having lips of a large size, and ears of no small length, do not only chase the beast while it liveth, but being dead also by any manner of casualty, make recourse to the place where it lieth, having in this point an assured and infallible guide, namely the scent and savour of the blood sprinkled here and there upon the ground. For whether the beast being wounded, doth notwithstanding enjoy life, and escapeth the hands of the huntsman, or whether the said beast being slain is conveyed cleanly out of the park (so that there be some signification of blood shed), these dogs with no less facility and easiness than avidity and greediness, can disclose and bewray the same by smelling, applying to their pursuit agility and nimbleness without tediousness. And albeit peradventure it may chance that a piece of flesh be subtilly stolen and cunningly conveyed away with such provisos and precaveats as thereby all appearance of blood is either prevented, excluded, or concealed, yet these kind of dogs by a certain direction of an inward assured notice and privy mark, pursue the deed-doers, through long lanes, crooked reaches, and weary ways, without wandering awry out of the limits of the land whereon those desperate purloiners prepared their speedy passage. Yea, the nature of these dogs is such, and so effectual is their foresight, that they can bewray, separate, and pick them out from among an infinite multitude and an innumerable company—creep they never so far into the thickest throng, they will find him out notwithstanding he lie hidden in wild woods, in close and overgrown groves, and lurk in hollow holes apt to harbour such ungracious guests. Moreover, although they should pass over the water, thinking thereby to avoid the pursuit of the hounds, yet will not these dogs give over their attempt, but presuming to swim through the stream, persevere in their pursuit, and when they be arrived and gotten the furthen bank, they hunt up and down, to and fro run they, from place to place shift they, until they have attained to that plot of ground where they passed over.” This treatise was so highly esteemed by Pennant that he inserted it in his British Zoology; and it was reprinted in a very neat form in 1880.[2] We need not particularise the very numerous editions and translations from Galen, Celsus, Hippocrates, which Dr. Caius published or left in manuscript. His own original medical works were the Method of Healing, based however upon Galen and Montanus, and the account of the sweating sickness, concerning which Hecker remarks, “Although, judged according to a modern standard, it is far from satisfactory, yet it contains an abundance of valuable matter, and proves its author to be a good observer.”[3]
