Received Smith's letter of 28 [March 1825]; sorry to hear he has been suffering from a rheumatic complaint in his eyes. Pleased Smith is satisfied with the willows he has so far gathered for his Salicetum; has not yet acquired 'Salix glauca'. Going to London at the end of the month but will be in London before Smith leaves, and hopes he will prevail on Smith to come and see the willows in full leaf, though fears there will be errors in the names. His health better than it has been for some time past, though has suffered from severity of the protracted winter.
