Another participant in the science propaganda was Dr. Thomas P. Jones, who devoted himself to Chemistry. The following notice of his lecture course is not devoid of interest: "On Saturday, the 13th inst., at seven o'clock in the evening, at Dr. Jones' Chemical Lecture Room, S.W. Corner of Fourth and Chestnut Streets, a lecture will be delivered on the properties of nitrous oxide, or the exhilarating gas, accompanied with a number of experiments. A large quantity will be prepared to exhibit its effects when inhaled. "Tickets at fifty cents each may be had at A. Finley's Bookstore, S.E. Cor. of Chestnut and Fourth Streets, or at the lecture room on the stated evening." On perusing early chemical texts and advertisements, such as those just given, attention is pointedly called to nitrous oxide, especially to its exhilarating properties, for then it was "_laughing gas_!" One Philip H. Nicklin published a brochure entitled "THE ONLY GENTEEL WAY OF GETTING DRUNK "A character representation of the effects produced by inhaling nitrous oxide gas. The accuracy of which no man breathing can deny. Price 25 cts." To-day, nitrous oxide means a benign anaesthetic, so helpful and merciful when one is brought under the knife of the skillful surgeon. The honor accorded Cutbush by his election to the Presidency of the Columbian Chemical Society was merited. He was not only an active, intelligent chemist, devoted to the advancement of his science in all directions, but he seems to have been an ardent enthusiast in the cause of education, for on the 7th of November, 1811, he delivered an Oration on Education before the Society for the Promotion of a Rational System of Education. His audience was large and consisted of the very best people of the city. The printed oration shows that in addition to his chemical knowledge he was versed in the humanities, in mathematics, in philosophy and ancient history. To-day the intelligent reader would pronounce the oration scholarly in every particular. His chief purpose seems to have been to introduce into what was then the customary curriculum in schools a definite amount of science--natural and physical. This is marked in the title of the organization before which he appeared on the occasion referred to, in Old St. John's Church. The whole community was interested in education. A society of educators had existed for a number of years. Neef had for a long time been advocating a system which was in reality a modification of the Pestallozian System, and men in every walk of life were seriously considering the innovations and advancements in this all-important subject.
