Chemistry is the study of the composition of substances, and the changes in composition which they undergo (Chambers 1988,154). Physics is concerned with the properties of matter and energy, and the relationships between them (Collins 1986,1157). This distinction between the composition of substances and their properties is rather artificial, since the properties of substances depend upon their composition. Nevertheless it does provide a convenient means of dividing science into two of its major branches and, by extension, dividing scientific instruments into groups.

Almost all the instruments in the collection in the College Museum can be grouped under the heading of physics, since in general terms they deal with the properties of materials rather than with their chemical composition. Since there are so many physics instruments, they are sub-divided into more specific areas in the rest of the Catalogue.

This first section, however, deals with instruments and apparatus which are related to the chemical composition of substances, or to means of studying it. Since they are rather few in number, they do not need further division here. Indeed the word "analysis" is added to allow the categories of goniometers and spectroscopy to be included without challenge. The measurement of crystal angles is aimed chiefly at understanding chemical composition, as is practical spectroscopy, hence their inclusion.
So-called "chemical" balances, which might be expected in this section, are listed under "Mechanics" (pages 215-217), on the basis that such balances are based on mechanical principles (moments) and can be used in investigations in all branches of science.

The following pages contain pictures and details of the chemistry instruments contained in the museum. Not all instruments are on display but viewing can be arranged by contacting the curator, Dr. Niall McKeith.

Topics covered include Burners, Goniometers, Spectroscopy, Chemical Glassware, and other apparatus.
