mathematical books and manuscripts to the College Library. He had been
appointed by Hariot to look over, arrange, and ' pen out the doctrine '
of his mathematical writings. Torporley's abstracts of Hariot's papers
are still preserved in Sion College Library.

What the Earl of Northumberland did for Hariot is, as the world goes,
ascribed to patronage ; what Hariot did for the Earl cannot be measured
by money or houses, but may be summed up in four words, alike honorable
to both, ' they were long friends.' To this day the debt of gratitude
from the philosopher to the nobleman is fairly balanced by the similar
debt of the nobleman to the philosopher. Hariot's Will, given on pages
193-203, tells the rest of the story of this noble friendship.

It is manifest, however, from many considerations that the noble Earl
took a lively and almost officious interest in the public honor and
character of his friend, for Hariot appears to have been as careless of
his own scientific reputation as his contemporary Shakspeare is said to
have been of his literary eminence.

On the other hand, Hariot's interest in the Earl's affairs and family at
Sion redound greatly to his credit. He was both an eminent scholar and a
remarkable teacher. Earnest students flocked to him for higher education
from all parts of the country. Besides the private scientific and
professional instruction that from the first he gave to Raleigh, his
captains and sea officers, he seems to have had under his scientific
tuition and mathematical guidance many young men who afterwards became
celebrated; among whom may be mentioned Robert Sidney, the brother of
Sir Philip, afterwards Lord Lisle of Penshurst; Thomas Aylesburyof
Windsor, afterwards Sir Thomas, the great-grandfather of two queens of
England; the late Lord Harrington; Sir William Protheroe and Sir William
