Emile Alluard, professor of physics at the University of Clermont-Ferand and director of the meteorological observatory on the nearby Puy-de-Dôme, described this type of hygrometer in 1878. A modification of Regnault's instrument, it consists of a square vessel made of polished nickel-plated brass. At either side of the vessel, but not touching it, are strips of similar material. In use, the vessel would be filled with ether, and this ether would be cooled by evaporation by means of an aspirating bulb. When dew appears on the shiny surface of the vessel, a thermometer in the vessel indicates the temperature of the ether at that point. A second thermometer measures the ambient temperature.
Robert A. Millikan described the Alluard hygrometer as being one of the "most perfect forms of the dew-point hygrometer" in his Mechanics, Molecular Physics and Heat, a popular college text that was first published in 1903 and that aimed "to present Physics as a science of exact measurement." This example is marked "A Sign of Quality WELCH A Mark of Service / W. M. Welch Scientific Company / ESTABLISHED 1880 / 1515 SEDGWICK ST. CHICAGO, U.S.A." It was made between 1921 (when the W. M. Welch Scientific Company began as such) and 1960 (when it became Welch Scientific). It is missing the aspirating bulb and both thermometers.

Joy McLean Bosfield was born on January 27, 1924 to John and Florence Mearimore. Her mother, an immigrant from Demerara, Guiana, married McLean's father, a prominent New York businessman, in March of 1923 in New Jersey. She lived with her family in Paramus, New Jersey until 1940, when she graduated from Ridgewood High School. During that same year McLean was accepted to the prestigious Hunter College, in New York. Her mother moved with her to New York City where they lived with Mrs. Mearimore's older brother. During her time in New York, McLean developed important relationships that helped shape her professionalism and creativeness. On February 26, 1945, McLean performed in her first recital at St. Martin's Little Theatre. It was the beginning of a long and distinguished career as a soprano opera singer. Three years after graduating and making her debut, she went on to perform at Carnegie Hall. In June of 1948, McLean married Charles McLean and moved to England. Mr. McLean, originally from British Guiana, wished to study law at London University, while Ms. McLean continued to develop her career by working for the BBC (British Broadcasting Corporation) as a solo soprano for several of their programs. In 1952 Ms. McLean toured with an American company of Porgy and Bess. Through the production she travelled all over the world including eastern and western Europe and the Middle East. When she returned to the United States, McLean joined several musicals and continued to give recitals and public appearances. At some point, McLean married Samuel Bosfield and began being known as McLean Bosfield. She claimed the name change reflected her many years as a public figure and the importance of the associated reputation it generated. Later in life, McLean moved to Washington D.C. with her husband where she continued to work on her career by giving recitals and performing as a piano accompanist. She also began working for the Frederick Wilkerson Studio of Voice as a vocal coach. After the death of Wilkerson, McLean took over the studio in the 1980s. She called it the McLean Bosfield Vocal Studio. Besides vocal training she also produced public recitals for her students. The final student concert of the studio was held on March 17, 1985. It was not only the final concert for the studio (Ms. McLean retired and closed the studio in 1985) but it would also be Ms. McLean's final public performance. With the death of her husband, Samuel Bosfield, and her mother in 1983 and 1984 McLean found no reason to stay in D.C. She moved to Chapala, Mexico in 1985 after reconnecting with an old family friend she knew when she lived in New York City while attending college. Upon moving to Mexico, McLean married her long time friend, Bill Jackson who was several years her senior and had moved to Chapala years earlier with his deceased first wife. Jackson and McLean spent several fruitful years together, participating in community theater productions and other community functions until his death in 1991 at the age of 91. On April 4, 1999, Joy McLean Bosfield died.
The collection, which dates from circa 1923 to 1995 and measures 3.41 linear feet, documents the personal life and career of opera singer and voice teacher Joy McLean Bosfield. The papers are comprised of personal and professional correspondence, concert programs, contracts, newspaper clippings, scrapbooks, photgraphs, radio scripts, and record albums.

The Smithsonian Institution was created by authority of an Act of Congress approved August 10, 1846. The Act entrusted direction of the Smithsonian to a body called the Establishment, composed of the President; the Vice-President; the Chief Justice of the United States; the Cabinet; the Mayor of Washington; and the Commissioner of the Patent Office. In fact, however, the Establishment last met in 1877; and control of the Smithsonian has always been exercised by its Board of Regents. The membership of the Regents consists of the Vice-President and the Chief Justice of the United States; three members each of the Senate and House of Representatives; two citizens of the District of Columbia; and nine citizens of the several states, no two from the same state. (Prior to 1970 the category of citizen-Regents not residents of Washington consisted of four members). By custom the Chief Justice is Chancellor. The office was at first held by the Vice-President. However, when Millard Fillmore succeeded to the presidency on the death of Zachary Taylor in 1851, Chief Justice Roger Brooke Taney was chosen in his stead; and the office has always been filled by the Chief Justice since that time.
These records are the official, edited minutes of the Board, compiled at the direction of the Secretary of the Smithsonian, who is also secretary to the Board. Manuscript minutes exist for the period from 1846 to 1856, and after 1891. Only printed versions exist for the years from 1857 to 1891.

In the late 19th century, the Russian chemist Dimitry Ivanovich Mendeleev developed several charts in which chemical elements were grouped according to common properties. The atomic theory of matter developed over the next century suggested that these groupings could be explained by similarities in atomic structure.
In 1924, Henry D. Hubbard of the U.S. National Bureau of Standards prepared the first edition of this "Periodic Chart of the Atoms." It included symbols for the elements, atomic numbers, atomic weights, and descriptions of atomic structure. In the course of the twentieth century, numerous new elements were discovered and added to the chart. Physical data on the properties of elements also was incorporated. Wall charts became a fixture of the chemistry classroom.
The Periodic Chart of the Atoms was revised regularly by the NBS and published by the W. M. Welch Science Company of Chicago. This is the 1963 version of the chart, as prepared by spectroscopist William F. Meggars. High schools could purchase the charts with aid from the U.S. government. Some chemists working on curriculum projects of the time also prepared new forms of the periodic table.

William Henry Holmes (1846-1933) was an anthropologist, archaeologist, artist, and geologist, who spent much of his career affiliated with the Smithsonian Institution. He studied art under Theodore Kauffman, and went on to work as a scientific illustrator with Smithsonian staff. In 1872, he was appointed artist-topographer to the United States survey of the territories under Ferdinand V. Hayden, and in 1874 was appointed assistant geologist. He went on to work with the United States Geological Survey (USGS), the Bureau of American Ethnology (BAE), until returning to the Smithsonian Institution, United States National Museum (USNM). Holmes eventually became head curator of the Smithsonian Institution's Department of Anthropology and Director of the National Gallery of Art.
This is the second of sixteen volumes compiled by William Henry Holmes in 1931 or 1932 to document his life and work. The volume contains original correspondences, documents, ephemera, watercolors, and photographs throughout. It is divided into four sections. The first contains a list of descriptions of his explorations from 1872 to 1920. Section two describes episodes and adventures from 1872-1920. This begins with a list of stories, which he describes using portions of letters, original field note books, news clippings, photographs (also with colleagues), and original drawings including a field drawing of a flower. This includes work completed with A. C. Peale and geological notes from Hayden expedition. Field work locations include Yellowstone, Colorado, and Mexico. Section three describes expositions between 1876-1916 across the United States in which U.S. Geological Survey and Smithsonian Institution took part. Section four documents the second Pan American Congress in Washington, D.C., during December 1915- January 1916; Fourteenth International Congress in Stutgart, August 1904; and the nineteenth International Congress during December 1915 - January 1916.

Short discussions of the sextant began appearing in physics texts in the 1880s, and inexpensive sextants suitable for pedagogical purposes followed soon thereafter. This die-cast metal instrument is of that sort. Welch catalogs describe it as a "convenient demonstration model of an engineer’s or a mariner’s sextant." The scale is graduated every 30' from 0° to 120° and read by vernier to six minutes of arc. A small bubble level is mounted on the sighting tube. The inscription reads "W. M. WELCH SCIENTIFIC COMPANY (/) WELCH (/) ESTABLISHED 1880 (/) 1515 SEDGWICK ST. CHICAGO. U.S.A."
