PREFACE
remainder that of Sillig (Gotha, 1851–3), excepting in some few instances, where, for reasons given in the Notes, it has been deemed advisable to depart from it. The first two Books, and portions of others, are the performance of the late Dr. Bostock, who contemplated a translation of the entire work; but, unfortunately for the interests of science, he was not permitted to carry his design into execution.
Upwards of a hundred pages had been printed off before the present Translator entered on his duties; and as they had not the advantage of Dr. Bostock's superintendence through the press, some trifling oversights have occurred. These are, for the most part, corrected in a short Appendix.
