Professor Sumichrast will give this evening at 8 o'clock in the Fogg Lecture Room, the third of his series of lectures, illustrated by the stereopticon, on "Paris during the Reign of Terror," the subject for tonight being "The Prisons." During the Reign of Terror the Revolutionary authorities increased the number of prisons in Paris from two to over forty. The lecturer will describe the chief of these, including the Temple, which became the abode of the royal family after it had been handed over by the Assembly to the Commune.

The fourth and last lecture of the series, on "The Peregrinations of the Guillotine," will occur next Wednesday evening.
