The lithological collection in Room B has been thoroughly re vised and to a considerable extent rearranged, and many new specimens have been added. An explanatory text or Guide simi lar to the guide published for the mineralogical collection has been planned for this collection.

Excerpt from Proceedings of the Boston Society of Natural History, Vol. 7: 1859 to 1861 A number of these chrysalids were kept, in order to ascertain if they would undergo metamorphosis, and, if so, whether the perfect insects would be healthy and vigorous; some were kept two months, at the end of which time they were accidentally lost, undergoing no change, remaining however in a perfect state of preservation and full of pulp; a number of small flies, apparently not ichneumons, which gained access to them, died almost immediately, as was supposed from having fed upon them - the empty shells of other chrysalids found about the room showed that some had been metamorphosed, as none but the arsenically-fed larvae had been admitted to the apartment. Experiments made to determine how large a quantity of arsenic might be contained in flesh without rendering it unfit for the food of these larvae, were not very satisfactory, from the hardening of the tissue by solutions of this substance preventing the deposition of the eggs; eggs developed in such tissue bring forth living worms, which in his experiments died in six or eight hours. The adult flies perished in great numbers, while depositing the eggs upon the poisoned flesh. Jaeger (quoted by Orfila, Toxicologic I. 379) alludes to the fact that larvae of flies live a little longer than the perfect insects, when arsenious acid is introduced into the digestive organs or applied to their external soft parts. Under favorable moist conditions, the larvae lived three or four days, and were evidently nearly ready to pass into the chrysalid state. Experiments with arsenic acid, used however in too concentrated a state, also showed that there is a limit to the amount of arsenic which these larvae can support. He was inclined to believe that they can eat with impunity any flesh into which arsenic has been carried by vital processes, from the fact of their being found upon the arsenicated liver, an organ capable of absorbing a very large quantity of this poison; anatomical preparations, injected thoroughly with arsenic acid, have been found completely riddled and alive with larvae.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Excerpt from Proceedings of the Boston Society of Natural History, Vol. 4: 1851-1854 At the conclusion of Dr. Warren's paper a letter was read by the Secretary, addressed to him by Mr. E. G. Squier, corroborating Dr. Warren's view of the true character of the so called "Aztec Children," containing the following statement: - "The Commandant of the Port of La Union, in the State of San Salvador, Central America, informs me that they were born somewhere near the town of Santa Ana, in that State, of parents, one of whom certainly, if not both, was dwarfed or deformed and imbecile. The Indians residing in the vicinity of Santa Ana are civilized, and centuries ago adopted Spanish customs and the Spanish language. So far as I could discover from a few words of their ancient language which came into my possession, they belong to the Cholutecan or Chorotegan stock, which, before the conquest, extended over a part of San Salvador, Honduras, and Nicaragua, but which was chiefly concentrated around the Gulf of Fonseca." Mr. T. T. Bouve read descriptions of a number of new species of fossil Echinoderms, from the Lower Tertiary rocks of Georgia, among others of the following: Catopygus patelliformis. Oblong-ovate, and rather pointed posteriorly. Superior face conico-convex, and forming with the inferior an acute margin. Ambulacral areas, narrow. Anus, transverse. The width of this species in proportion to the length, is as 7 to 10; height to length as 9 to 20. Description of characters from specimens in the collection of the Boston Society of Natural History.
