6. EXPORTS OF PETROLEUM OILS AND ITS PRODUCTS FROM ALL THE PORTS OF THE UNITED STATES. (1) CONTINUATION. The value of the totals is given in dollars, of the gallons in cents. (These notes refer to the tables on the two preceding pages.) 1. Compiled from the "Annual Report of the Chief of the Bureau of Statistics on Commerce and Navigation.-Domestic Products." 2. Petroleum, crude and refined: This statement was not fully reported in the Collector's returns, Petroleum not then being among enumerated articles.—“Report.” 3. The quantities and values of Petroleum exported were not reported in the Schedules of enumerated articles. The quantities and values here entered are derived from special enquiries and are below rather than above the actual exports.—“Report.” 4. The figures of this column to 1871 inclusive and the figures marked 4 for 1878 give gallons of solid Paraffin taken to weigh seven pounds each. 5. The figures of this column up to 1871 inclusive comprise a portion of Coal Oil reported by the Collector as follows: |1,144,769 gallons.|$676,444|59.0 cents per gallon. 1864. 1865. 1866. 1867. 1868. 1869. 1870. 1871. 821,088 80.5 456,955 61.2 242,283 43.2 6. This figure includes coal oil 521,053 gallons worth $187,866 or 36.1 cents per gallon. 7. The figures in this column are given in the schedules to 1869 inclusive as Benzine; in 1870 Benzine and Naphtha are given separately, and in 1871 and following they include Gasoline, Naphtha and Benzine. 8. The figures in this column indicate Residuum, Tar, Pitch, etc.; they are given.in the "Reports" in barrels, which I changed into gallons by assuming the barrels to hold 42 gallons, and making the multiplication. 8a. Is the value of Residuum, Tar, Pitch, etc., the quantity of which is not stated. 9. These figures were obtained by dividing the number of gallons by 42. 7. CHEMICAL COMPOUNDS DISCOVERED IN AND SEPARATED FROM AMERICAN PETROLEUM. F.-Fouque; R,-Ronalds; W.-Warren; P. and C.-Pelouze and Cahours; S-Schorlemmer. I. IMPURITIES NOT YET ISOLATED. Those possessing in their composition Sulphur. 2. Those which give rise to the color of Petroleum. 3. Those possessing the disagreeable and specific ordor of American Petroleum. In this list Thallen, discovered by Prof. Morton is not mentioned, because it is probably only an educt of the distillation of Petroleum at high temperatures and not a product occurring in it naturally, and further because L. Prunier and R. David, Comptes rendus 87, pgs. 991-93, state that Petrocen, Carbocen, Carbopetrocen and Thallen are only mixtures with from 88 to 96 per cent. of Carbon. (*) These three tables are taken from C. F. Chandler's "Re port on Petroleum," 1871. (†) This table is taken from H. B. Cornwall, "Petroleum," 1876. TABLE. Condensed by pump, made by one firm only for an ice machine, boils at 32° F. Condensed by ice and salt, used as an anesthetic, boils at 65° F. Condensed in worm by cold water, used in "air gas machines" and gas "carbonizers." For oil cloths, cleaning, etc.; so-called "Safety oil," "Danforth's oil," "American Safety Gas," etc.; for adulterating kerosene, cleaning oil wells. Semi-solid when cold. Chilled and pressed to separate paraffin, oil used for lubricating. |
