Although he is not named on the title-page or in the text, Trinity College, Dublin, ascribes this work to a John Gregory in its library catalogue. *** The preface to this second edition states that the work has been revised with special attention being given to conic sections. It exhorts teachers to direct their pupils to learn only such portions of the work as may be necessary for their intended occupations. At the start of this volume is the separately printed, four page, 'Selections from the "Rules and Regulations of the Commissioners of National Education in Ireland," bearing on the subject of Religious Instruction, for the information of the Parents of the Children attending National Schools.' *** Some dusting to cover and slight computational annotations to text, otherwise a very good copy without any damage, library stamps, inscriptions or other markings.…
