Sends a number of theorems and integrals.
Sends numbers as usual and encloses £15 note. Also sends a little bit of ulmin on elm bark, finds similar substance on oak, hornbeam, and horse chestnut and asks Smith's botanical friends to look out for it; has recommended it to the Society of Arts as excellent for finishing in water colours, in same way that Sir Joshua Reynolds [(1723-1792), painter] used 'Asphaltum' in oil.
Requests Smith to revise enclosed 4 numbers of "English botany" and number enclosed in last.
