My nieces<2> have been attempting to draw upon smoked glass, but have not been able to fix in any manner the smoke on the glass.<3> I understood you to recommend that varnish should be put over it after it had been smoked, which operation we have been quite unable to effect. You would therefore much oblige me by some further explanation. All attempts have hitherto failed in consequence of the impossibility of keeping an even coat of black.
Caroline & the children <4> are quite well. I cannot boast about myself.
2. Valletort had five nieces through his sister, Lady Caroline Sophia Edgcumbe (d. 10 April 1824), who was the first wife of Reginald George Macdonald (d. 1873).

Louisa Emily (sometimes Emily Louisa) (d. 1897) married Charles William Marsham on 13 April 1841. The Honorable Flora Isabella Clementina (1822-1899) was Maid of Honor and later Woman of the Bedchamber to Queen Victoria. In 1848, Annie Sarah (sometimes Sarah Anne) married Alfredo Salvatori Ruggioro Andrea, Baron Porceilli di Sant Andrea, a Sicilian nobleman and revolutionary commander.
3. Later, in the hands of Barbizon artists, this artistic process became known as cliché verre. WHFT employed it in 1834. The artist would take a smoked or varnished piece of glass, cut lines through to create the image, and then print this on WHFT's photogenic drawing paper. An example is illustrated in Larry J Schaaf, The Photographic Art of William Henry Fox Talbot (Princeton: Princeton University Press, 2000), plate 2.
