Interesting how this thread of mine has drifted into the 1950s AlanRoss/NancyMitford 'U&non-U'/'NoblessOblige' controversy — anticipated by the Hon Nancy in her novel 'ThePursuitOfLove'[1945] ['serviette' rather than 'table napkin' being one of her main markers]; &, as we learn above, even further anticipated [1906? cor!] by one Bland, as adduced by Q above.

drift - drift - drift ··· How Delightful: just like Ratty's 'messing about in boats'...
