Tuesday May 8, 1894
Mr Crisp came down with Mr Grundy about warming Physical Obsy by hot air.
William Christie, Astronomer Royal
RH says.... Some information about Mr Grundy and his company can be found here. The company (under John Grundy senior) filed a patent for heating rooms and buildings by hot air in 1864, a system that was adapted with improvements patented in 1889. This drawing is, I assume, from the original patent and may reflect what is still present in today's South Building at the ROG.
