2013.3.87Description
Description from L.A. Brown's 1959 catalog: "Mounted on its own table, which has a drawer for spare parts, this machine was dismantled by students in an effort to clean it. They were unable to reassemble the parts and now some of them (one glass cylinder, for example) are missing. This pump was purchased by Drs. Peter and Bush from Deleuil of Paris for 400 francs in 1839.
The earliest Deleuil catalogue we have seen was one issued in 1865. But this catalogue states that the Deleuil firm was established in 1820. It also shows that Deleuil won the Médaille d'argent" in an exposition held the same year (1839) in which Dr. Peter bought extensively from the firm. In 1851, at the time of the Great Exhibition of London, Deleuil had both a Paris and a London address."Collection
