About this source

What it is

This is a page of technical diagrams from a scientific paper written in 1795 by Thomas Beddoes and James Watt. The plate shows laboratory apparatus such as a pneumatic vessel, a spiral coil, and a gas vessel, each labelled with letters.

Why it matters

Watt is best known for his work on the steam engine, but this document shows him also contributing to chemical and medical research alongside Beddoes. It reveals the close links between engineering and the wider scientific world of the late eighteenth century.

Look closer

What do the careful labels and measurements suggest about how this apparatus was meant to be built or used?
Why might an engineer like Watt be involved in designing scientific instruments for a chemist?
What questions might this one page leave unanswered about what the experiment was actually testing?
