Book excerpt: Excerpt from Memoirs of the National Academy of Sciences, Vol. 8 This work was undertaken at the instance of Dr. John S. Billings, Director of the Laboratory of Hygiene, University of Pennsylvania, with the view of obtaining, if possible, some explanation, from a bacteriological standpoint, of the greater mortality among persons living in houses built on made ground over those living on virgin soil. In some cities, as Washington and New York, filled localities can be mapped out and the course of old runs followed by the higher death rate in these districts. N 0 positive opinion can be based on the data so far obtained, and these notes are presented mainly as a small contribution to our knowledge of the bacteria of the soil. In the prosecution of the work I have had the advice of Dr. Billings and of Dr. A. C. Abbott, first assistant, to both of whom I am much indebted.

Samples of made soil were obtained in the same way to a depth of 9 feet. Other samples of both made and virgin soil were obtained by Frankel's earth borer to a depth of 55 feet.

This book was released on 2018-09-09 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Memoirs of the National Academy of Sciences, Vol. 17 Perhaps the most eminent and interesting man associated with me during this period was Mr. George W. Hill, who will easily rank as the greatest master of mathematical astronomy during the last quarter of the nineteenth century. The part assigned to Hill was about the most difficult in the whole work - the theory of Jupiter and Saturn Owing to the great mass of these giant planets, the inequalities of their motion, especially in the case of Saturn, affected by the attraction of Jupiter, are greater than in the case of the other planets. Leverrier failed to attain the necessary exactness in his investigation of their motion. Hill had done some work on the subject at his home in Nyack Turnpike before I took charge of the office. He now moved to Washington, and seriously began the complicated numerical calculations which his task involved. I urged that he should accept the assistance of less skilled computers; but he declined it from a desire to do the entire work himself. Computers to make the duplicate computations necessary to guard against accidental numerical errors on his part were all that be required. He labored almost incessantly for about 10 years, when be handed in the manu script of what now forms Volume IV 6 of the Astronomical Papers. And here was perhaps the greatest living master in the highest and most difficult field of astronomy, winning world-wide recognition for his country in the science, and receiving the salary of a department clerk. I never wrestled harder with a superior than I did with Hon. R. W. Thompson, Secretary of the Navy, about 1880, to induce him to raise Mr. Hill's salary from to It goes without saying that Hill took even less interest in the matter than I did. He did not work for pay, but for the love of science. That I could not secure for him at least the highest official consideration is among the regret ful memories of my official life.
