Research Facts
These objects are normally used to measure distances on maps. They were produced by a French company who would not sell to North America, therefore they had to be purchased in Europe.

Description
A student's molecular model kit in a box consisting of 20 white wooden balls, 12 black, 7 red, 17 green, 4 yellow, and 4 orange and 32 small metal springs; each ball has several holes drilled into it for the springs to be inserted; the box is coated in leatherette and has several compartments for holding the different coloured balls and consists of a base (a) and a lid (b).
Note: The curatorial staff decided it would be better not to individually number each ball and spring in the interests of saving time, and because it would be difficult to hide the numbers if the objects were ever put on exhibit.

Research Facts
Cyclopropane is an anaesthetic when inhaled. In modern anaesthetic practice, it has been superseded by other agents, due to its extreme reactivity under normal conditions: when the gas is mixed with oxygen, there is a significant risk of explosion. Cyclopropane had no commercial application until Henderson and Lucas discovered its anaesthetic properties in 1929; industrial production had begun by 1936. This meant induction of anaesthesia by inhalation of cyclopropane and oxygen was rapid and not unpleasant. However at the conclusion of prolonged anaesthesia patients could suffer a sudden decrease in blood pressure, potentially leading to cardiac dysrhythmia; a reaction known as "cyclopropane shock".For this reason, as well as its high cost and its explosive nature, it was latterly used only for the induction of anaesthesia, and has not been available for clinical use since the mid 1980s. Cylinders and flow meters were coloured orange. Cyclopropane, also called trimethylene, explosive, colourless gas used in medicine since 1934 as a general anesthetic. Cyclopropane is nonirritating to mucous membranes and does not depress respiration. Induction of and emergence from cyclopropane anesthesia are usually rapid and smooth. A mixture of about 5 to 20 percent cyclopropane in oxygen is administered by inhalation. Because of the flammability and expense of cyclopropane, it is usually used in a closed (rebreathing) system, in which an absorbent chemical, such as soda lime, removes exhaled carbon dioxide, and the anesthetic is recirculated. The chemical formula is C3H6.
