Letter from C [Charles] Pritchard, to Sir John [Frederick William Herschel] Pritchard suggests that Aleck [Alexander Stewart Herschel] exercises caution, not to be a 'cat's paw for canny ones at Glasgow'. He knows that Mr [John Peter] Gassiot and Mr [Warren] De La Rue are looking to get something for Aleck. Pritchard talked it over with Gassiot last Sunday and he is much interested. 18 March 1866
