The young gentleman and lady's assistant : partly original, but chiefly compiled from the works of the most celebrated modern authors; calculated to instruct youth in the priciples of useful knowledge: in five parts, viz. geography, natural-history, elocution, poetry, --and miscellany. To which is annexed --a short system of practical arithmetic; wherein every example is wrought at large, and the whole, including the money of the United States, rendered easy to the meanest capacity. This work, is divided into small sections for the convenience of schools. By Donald Fraser, school-master, New-York
