6.9.1807 Carlisles, Buchan & John Flather call / 16.11.1807 Carlisle, Buchan & mrs Topping call / 18.11.1807 Jo(seph) G(odwin) calls, & Buchan (not seen) 
The GD website has a person record for Dr Alexander Peter Buchan (DNB 1764-1824), but the above entries are not coded to him. Although calls on the same day could have been quite separate, the fact that Buchan followed Carlisle on the first two entries above suggests that this was Dr Alexander Buchan, a known associate of Anthony Carlisle, and so presumably was the third entry, only two days later.
