The Greeks accounted for the early rise of the science of geometry among the Egyptians by reference to the necessity they were under each year of re-establishing the boundaries of their fields—the inundation obliterating old landmarks and divisions. The science thus forced upon their attention was cultivated with zeal and success. A single papyrus has been discovered that holds twelve geometrical theorems.
Arithmetic was necessarily brought into requisition in solving astronomical and geometrical problems. We ourselves are debtors to the ancient Egyptians for much of our mathematical knowledge, which has come to us from the banks of the Nile, through the Greeks and the Saracens.
Medicine and the Art of Embalming.—The custom of embalming the dead, affording opportunities for the examination of the body, without doubt had a great influence upon the development of the sciences of anatomy and medicine among the Egyptians. That the embalmers were physicians, we know from various testimonies. Thus we are told in the Bible that Joseph "commanded the physicians to embalm his father." The Egyptian doctors had a very great reputation among the ancients.
Every doctor was a specialist, and was not allowed to take charge of cases outside of his own branch. As the artist was forbidden to change the lines of the sacred statues, so the physician was not permitted to treat cases save in the manner prescribed by the customs of the past; and if he were so presumptuous as to depart from the established mode of treatment, and the patient died, he was adjudged guilty of murder.

The Egyptians believed that after a long lapse of time, several thousand years, the departed soul would return to earth and reanimate its former body; hence their custom of preserving the body by means of embalmment. In the processes of embalming, the physicians made use of oils, resin, bitumen, and various aromatic
