| Title | Letter from Jean-Baptiste Biot to Thomas Young |
| Date | nd |
| Description | Delighted to have read Young's critique of his early works on optics. Hopes he will read his later experimental work as it furthers his findings in particular on polarisation. Includes a demonstration on the polarisation of light through crystals to discuss how light splits to support the theory that light moves as molecules rather than waves. Has also presented a new instrument to support his optical experiments at the Institut [de France].
As a postscriptum reassures Young that there was no space between the two slides in his experimentation and includes a small figure in the margin to show who the water was placed between the glass slides. |
