'He was the first introducer [in the above work] of a complete trigonometrical canon into English, the first announcer 

 of Wright's discovery of meridional parts, and exercised much influence on the studies of the first part of the XVIIth 

 Century. Nor is he altogether out of date yet ; for I lately observed (Mechanic's Magazine, v. XLIV, p. 477) that a patent 

 for an improvement in horse-shoes was upset in the Court of Chancery, on proof that Blundevile had described it in one of 

 his works. The first of these exercises is a treatise on arithmetic, in the form of question and answer, written for 

 Elixabeth Bacon, the sister of the great philosopher. It is a dogmatical treatise, sufficiently clear.' Prof, de Morgan.
