in the Church of St Alphage, close by.  In a nuncupative will spoken the 14th ofApril, a copy of which is before the writer, he left his books and manuscripts to the Sion Col ege Library.  A complete list of about 170 books and several manuscripts is preserved in the ’ Donors’ Book.’  A few of the books are said to have been destroyed by the fire of London, but probably none of the manuscripts were lost.

Torporley’s manuscripts, as has been stated, have often been referred to, and sometimes copied, but their true history and character is explained by Hariot’sWill.  There are really but two manuscripts relating to Hariot.  The more important one comprises 116 closely-written folio leaves, or 232 pages, all in Torporley’s handwriting.  It bears no title or designation.  Hence various writers who have seen it, from Collins, Wood, and Dr Zach, have given it different names, such as, ’Ephemeris Chysometria,’ ’Congestor opus Matbematicum,’ etc. but it appears to be nothing more nor less than Torporley’s attempt to pen out such doctrine as he found in Hariot’s papers.  The leaves are numbered, 1 to 16 containing a Treatise on Hariot’s Theory of Numbers.  Leaves 17 to 25 are tables of the divisors of odd numbers up to 20,300.  On the verso of leaf 25 the Theory of Numbers is resumed, extending to the recto of 27.  On the verso of leaf 27 begins the treatise on the properties of Triangles and ends on leaf 34.  Leaves 35 to 55 comprise examples of Algebraical processes, and leaves 56 to 116 contain Tables (probably tabulæ sinuum ?) up to 180°.  On the second leaf the Author speaks of himself as working out, or working on Hariot’s principles, and also as making use of the writings of Vieta.  He adds: 

’ And since it is our principal design to explain the improvement in this science[the Properties of Numbers and Triangles] discovered by our friend Thomas Hariot; but he neither completely reformed it (which indeed was not necessary) nor gave a full account of it, but only strengthened it where it was defective, and by treating in his own way the points of the science which were heretofore more difficult, rendered them clear and easy.’

This manuscript was probably intended for another printed volume of Hariot’s mathematical works, but owing to the deaths about the same time, 1632, of the venerable editor and the noble patron this work never bore a definite name and never saw the light of the press.
