"Mr. Jeremiah J. Foster, 'On the History, Nature and Properties of Oxygen Gas.' "Mr. J. C. Foster, 'Objections to the Antiphlogistic Theory of Combustion.' "Mr. Charles Gignilliat, 'On Hydrogen Gas.' "Mr. John Bent, 'On Oxygen Gas.'" The monthly meetings were announced in the city papers. The announcements appeared at intervals through a period of years, hence it may be assumed the Society was an active organization and that its members regarded it as of consequence. The personnel of its official family is not devoid of interest at present. A single volume of memoirs, printed in 1813, is still extant and may occasionally be seen; from it will be learned that the "Hon. Thomas Jefferson, Esq., was the Patron" of the Society and its President was "James Cutbush, Esq., Professor of Natural Philosophy, Chemistry and Mineralogy in St. John's College." Turning to the table of contents two contributions from the President are observed. The first relates to the "Prognostic Signs of the Weather" and the second is "On the Oxyacetite of Iron as a Test or Reagent for the Discovery of Arsenic." There is little chemistry in the first contribution, and the second possesses value chiefly in the qualitative way. They were evidently dashed off with the idea of arousing discussion, in the hope that serious efforts might be set in operation in certain directions. The thought which intrudes itself in looking through the _Memoirs_, noting the character of the individuals in the membership, and upon recalling the chemical activities of Cutbush, is as to the man himself. Why should he, barely twenty-three years of age, be chosen to such an important and prominent station as that of President of the Columbian Chemical Society? What manner of man was he? What his qualifications, his fitness and his position in the science world of Philadelphia? A search through ancient volumes in many libraries failed to bring to light any facts bearing on these points. The only fact discovered that had any value came from a newspaper advertisement bearing the date October, 1819. It read: "_Bleaching Liquor_, _Artificial Musk_, _Phosphate of Mercury and other chemical Preparations_, prepared and sold by "JAMES CUTBUSH "Chemist and Apothecary "No. 25 South Fourth Street, Phila. "where complete collections of chemical reagents are kept as usual." Here is a hint as to the occupation of Cutbush. He was a chemist--presumably a manufacturing chemist, supplying the necessary reagents to persons desiring them for their chemical studies; and further he was a pharmacist serving the various requirements of the medical men of the City. Thorough search through newspaper files disclosed that from the year 1811 and perhaps two years earlier, and extending up to the year 1813--various announcements were made by Cutbush as to lectures of a public nature. These help us realize the character of the individual and his work. For example--
