Cabot, John

The carbon blacks consisted of Spheron 6 and Sterling FT (fine thermal) black, both non-heat-treated and 2700° C. heat-treated (obtained from the Godfrey L. Cabot Co., Boston, Mass.). Published surface areas for the four carbon blacks are 114, 84.1, 15.5, and 12.5 sq. meters per gram, respectively (31). The silica sand was supplied by the New Jersey Silica Sand Co., Millville, N. J., with the manufacturer s designation of No. 325 flour. Screen analysis by the supplier showed a considerable range in particle size about 60% was retained on a 90-mesh screen and 90% on a 200-mesh screen. Finally, a sample of asbestos was tested (obtained from the Canadian Johns-Manville Co., Port Credit, Toronto, with the designation 7R). Zettlemoyer (31) has studied this material.

The sixteenth and seventeenth centuries saw an explosion in world exploration. It had been preceded by the Italian Columbus s voyages to the Americas with John Cabot, the Englishman, close on his heels. Verrazzano searched for a Northern Strait (1524-1528), while Cartier too plied the coast of North America (1534-1536) in search of riches. 

It has been pretended that John Cabot had sighted the continent in the previous year, but this is not so. He only sighted Cape Breton and other islands. In his second voyage he sighted the continent (1498), but the month is unknown.
