I asked this in a separate thread some months ago and got nil response, but as there are evidently a few poets and lit. historians following this thread, perhaps I could try it out on you again?

The Oxford Dictionary of Quotations (5th Ed.) has the following verse from a poem called 'The Law Student' by Robert Lloyd, 1733 - 1764:

"Alone from Jargon born to rescue Law,
From precedent, grave hum, and formal saw!
To strip chicanery of its vain pretence,
And marry Common Law to Common Sense!"

I'd like to find the rest of it, but I've looked high and low. Anthologies of 18th Century poetry seem to have two or three of Lloyd's poems but never this one, and I've seen no sign of a "Robert Lloyd Complete Works" - presumably because he died too young to complete very much!

The poem, or this verse at any rate, is about the famous reforming Lord Chief Justice of the time, William Murray (Lord Mansfield). It seems to be an 18th Century plea for plain language in the law. 'Jargon' presumably has the same meaning we'd give it today; 'Hum' (humbug) is a cheap deceit; 'saw' is in the sense of a maxim; 'chicanery' is also deceit. Mansfield was known for his clear and straightforward style when summing up or making judgements, and he often went out of his way to explain judgements to law students observing court cases.

If this is thread creep I apologise, but at least we're still in the same branch of art!
