The last of the three, Dr Keith McArthur Brown, (d. 1962) wrote an account of medical practice in Parramatta which includes descriptions of Pringle's work.

[10] He describes the treatment of a wound of the forearm sustained by the accidental discharge of a shotgun into an area some three inches above the left wrist joint: "I recommended immediate amputation" he wrote "more especially having the dread of secondary haemorrhage and lockjaw before my eyes; but neither the patient nor his relatives would consent to this, and begged for me to try to save the limb.

He went on "Suffice to say that in dressing the arm this morning, the 34th day from receipt of the injury, I find that the whole wound has completely healed up, thus converting a compound into a simple fracture.

No pus whatever has appeared ... firm union has taken place between the ends of the ulna and satisfactory progress made with the radius, perfect motion and sensibility retained in the hand".

And be it remembered, this is no quack remedy, but the result of patient scientific enquiry and thought on the part of that ‘philosophical investigator’ Joseph Lister".

[14] Pringle’s decision to publicise this case in a newspaper was criticised in subsequent correspondence to the Sydney Morning Herald.

He died, probably from dysentery, on board the sailing ship Parramatta on 31 March 1872 aged 41 while returning to Australia from a further visit to Britain and was buried at sea.
