Thanks for Smith's letter and "friendly documents & information", unfortunately they came too late for him to alter names [in his "Menthae Britannicae"], as the plates are all finished and letterpress almost finished; the work has been slightly delayed by his ill health. Explains his garden catalogue system. Hopes there are not too many "blunders" in his work, and if he finds any contradictions with Smith's letter will add his observations as a postscript.
