Book excerpt: Excerpt from Bulletin of the Chicago Academy of Sciences, 1883, Vol. 1 True to the habits of the spiders to seek those places for their homes that flies frequent. There is one that makes its home at the top of the leaves spinning its web so that it nearly covers the whole Opening. In each case that I have observed it is the same species but whether it always seeks the pitchers, I cannot state. An insect lighting upon the leaf starts immediately to walk toward the inside. It seldom stops till the smooth place is reached where sooner or later it loses its foot-hold and falls. In some cases they try to fly upward from the bot tom of the pitchers. In but one case have I seen an insect escape in this man ner. This, a beetle, obtained its freedom by flying from one side of the tube to the other till the opening was reached. A slight secretion has been observed by many near the opening of the pitcher. This seemingly has but little power to attract insects, though at times it is quite copious. Mr. Joseph Jackson says, While collecting a few specimens of S. Pur purea. L I was surprised on drawing aside the petals to look at the stamens to see the whole cavity formed by the petals and the peltate expansion of the style filled with flies as large as the common house fly, all busy as could be eating the pollen, of which scarcely a grain could be seen. I counted fourteen flies in one flower. They were in no hurry to vacate the premises. There was a shower coming up at the time. But they were evidently there for food. Nearly every plant examined was filled in the same way. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book William Stimpson and the Golden Age of American Natural History written by Ronald Scott Vasile and published by Northern Illinois University Press. This book was released on 2018-06-19 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: William Stimpson was at the forefront of the American natural history community in the latter half of the nineteenth century. Stimpson displayed an early affinity for the sea and natural history, and after completing an apprenticeship with famed naturalist Louis Agassiz, he became one of the first professionally trained naturalists in the United States. In 1852, twenty-year-old Stimpson was appointed naturalist of the United States North Pacific Exploring Expedition, where he collected and classified hundreds of marine animals. Upon his return, he joined renowned naturalist Spencer F. Baird at the Smithsonian Institution to create its department of invertebrate zoology. He also founded and led the irreverent and fun-loving Megatherium Club, which included many notable naturalists. In 1865, Stimpson focused on turning the Chicago Academy of Sciences into one of the largest and most important museums in the country. Tragically, the museum was destroyed in the Great Chicago Fire of 1871, and Stimpson died of tuberculosis soon after, before he could restore his scientific legacy. This first-ever biography of William Stimpson situates his work in the context of his time. As one of few to collaborate with both Agassiz and Baird, Stimpson's life provides insight into the men who shaped a generation of naturalists--the last before intense specialization caused naturalists to give way to biologists. Historians of science and general readers interested in biographies, science, and history will enjoy this compelling biography.
