Nor was it altogether a reflecttheories. Astronomy, which had once meant only observing the stars, now became in addition a matter of abstruse mathematics, and the calculus played as important a part in its history as the telescope. But women, by their valuable work, had made a place for themselves in the astronomical world, and the time soon came when the work could not be carried on without their assistance. About the middle of the eighteenth century, Alexis Claude Clairaut, a noted mathematician and astronomer, was asked to predict when Halley's comet would return to perihelion, i. e., come closest to the sun. This involved long, difficult calculations, and he freely admitted his inability to complete the task alone. “But,” said he, "if Madame Lepaute will assist me, I will undertake the task.” Mme. Nicole Reine Lepaute was the wife of the watchmaker to Louis XV., and she often helped her husband in his calculations for astronomical pendulums. She gladly consented to assist Clair
