David Jury has posted the further usage in "Kim": " He learned to wash himself with the Levitical scrupulosity of the native-born, who in his heart considers the Englishman rather dirty." Thanks. Here with the dictionary capital L. The Book of Leviticus has numerous references to washing and cleanness, so I think this is a more conventional use of the term. Both here and in the Bull story I see a clear Biblical reference, not merely "meticulous" [per Michael & Mary]. My Roget's Thesaurus [1967] does not index "Levitical", confirming that it is an unusual term. Bryan
