Dr. Caius is credited with having predicted the very day of his death. He had his own grave prepared in Caius College Chapel, on the 2d, 3d, and 4th of July, 1573, and died at his London house on the 29th of the same month, aged sixty-three. His body being removed to Cambridge as he had directed, the master and fellows of his college and the principal members of the university in procession met it at Trumpington. The inscription on his tomb in Caius Chapel is characteristic of the man, in whose eyes his own works and achievements, undoubtedly considerable, loomed large. “Vivit post funera virtus,” as he had recorded on Linacre’s monument. “Fui Caius,” he adds, as a pithy if egotistic comment. * * * * * Among other notable men of the sixteenth century must be mentioned WILLIAM GILBERT, M.D., a native of Colchester, who was born in 1540, and became senior fellow of St. John’s College, Cambridge, in 1569. Having settled in London in 1573, his distinction was such that he became physician to Queen Elizabeth. But he was one of the first of the illustrious series of English physicians who employed their leisure in philosophical research. By his book, “On the Magnet, on Magnetic Bodies, and the Great Magnet the Earth,” published in 1600, he had the good fortune to become the stimulator of Galileo himself to the study of magnetism, and that master described him as “great to a degree which might be envied.” Queen Elizabeth added to her titles to regard by conferring a pension on Gilbert, which aided him in prosecuting his experiments. Gilbert was in fact a great originator in science, having discovered the earth’s magnetism, and that to this is due both the direction of the magnetic needle north and south, and the variation and dipping of the needle. Thus he stands as the discoverer of the facts on which the science of magnetism was based. He is said to have been no less exact in chemistry, but unfortunately nothing of his is extant on that subject. Fuller says of him in the “Worthies”—“Mahomet’s tomb at Mecca is said strangely to hang up, attracted by some invisible loadstone; but the memory of this doctor will never fall to the ground, which his incomparable book, ‘_De Magnete_,’ will support to eternity.” Gilbert died in 1603, shortly after being appointed physician to James I.

CHAPTER II. _WILLIAM HARVEY AND THE CIRCULATION OF THE BLOOD._ “Oft have I seen a timely-parted ghost, Of ashy semblance, meagre, pale, and bloodless, Being all descended to the labouring heart, Who in the conflict that he holds with death, Attracts the same for aidance ’gainst the enemy; Which with the heart there cools, and ne’er returneth To blush and beautify the cheek again.”
