text: While not credited for direct research into the field of pneumatic chemistry, Boerhaave (teacher, researcher, and scholar) did publish the Elementa Chimiae in 1727. This treatise included support for Hales work and also elaborated upon the idea of airs. Despite not publishing his own research, this section on airs in the Elementa Chimiae was cited by many other contemporaries and contained much of the current knowledge of the properties of airs. Boerhaave is also credited with adding to the world of chemical thermometry through his work with Daniel Fahrenheit, also discussed in Elementa Chimiae.'
