"American contributions to Chemistry. By Benjamin Silliman." v. 5, p. 70-114, 195-209.

"Beginning with Dr. Marie Maynard Daly, the first African American woman to receive a PhD in chemistry in the United States--in 1947, from Columbia University--this well researched and fascinating book celebrate the lives and history of African American women chemists. Written by Jeannette Brown, an African American chemist herself, the book profiles the lives of numerous women, ranging from the earliest pioneers up until the late 1960's when the Civil Rights Acts sparked greater career opportunities. Brown examines each woman's motivation to pursue chemistry, describes their struggles to obtain an education and their efforts to succeed in a field in which there were few African American men, much less African American women, and details their often quite significant accomplishments. The book looks at chemists in academia, industry, and government, as well as chemical engineers, whose career path is very different from that of the tradition chemist, and it concludes with a chapter on the future of African American women chemists, which will be of interest to all women interested in a career in science"--

Not illustrated. 1894 edition. Excerpt: ...say, 500 fathoms of the surface. I remember that when the Valorous ran a line of soundings across the North'Atlantic in August, 1875, we got 1,860 fathoms on one day, 1,450 on the next, and only 690 on the next, bringing up pieces of black volcanic stone. On the two following days the depth increased to 1,250 and 1,485 fathoms. Here there was clearly either a volcanic peak or a ridge; and wherever these are known to occur I think that it would be very desirable to explore the surrounding ocean bed and ascertain their extent and character. We want also the establishment of a more complete study of the system of ocean currents by a very extensive use of floats adapted to swim at various depths, and also a fuller investigation of the temperature and density of the water surrounding the shores of all the continents. The work hitherto done in the North Sea and the neighboring Atlantic is practically confined to the summer months, and a detailed examination at all seasons is needed. Such work is now being done under the auspices of Profs. Petterssen, of Sweden, and Mohn, of Ohristiania, Kriimmel, of Kiel, and the fishery board of Scotland. We also require a determination of the isotherms and isobars on land and sea at all seasons, which will primarily involve prolonged observations in the South Polar region, and a more 0I_I1plete knowledge of the variation of atmospheric pressure with hfilght, and its independent variation in different horizontal planes. Such an investigation embraces the whole question of the use of the bflfvlneter or boiling-point thermometer in measuring heights. This will conclude my enumeration of the geographical desiderata in the field. It is a long and formidable list, aflording work for many decades f Years to...
