 ' 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

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

 Elizabeth Bacon, the sister of the great philosopher. It is a dogmatical treatise, sufficiently clear.'— Pro/, de Morgan.
