Lot Essay
Lamb and Collins illustrate and describe the second edition of this work as item 4.60, giving the publishers as Thomas Wright and Richard Cushee, commenting that: "Joseph Harris's text covers some 50 tasks which can be solved with the help of a globe, as well as a description of the newly devised orrery. Both Thomas Wright and Richard Cushee were involved as publishers and sellers of this useful manual on globes" (p.62). Dekker and van der Krogt describe the work as, "a popular text book in the eighteenth century" (p. 106). Clifton notes that E. Cushee took over from Richard Cushee in 1734, and that this work had reached a tenth edition in 1768 (p. 74).
