Lister tested the results of spraying instruments, the surgical incisions, and dressings with a solution of carbolic acid. Lister found that the solution swabbed on wounds remarkably reduced the incidence of gangrene. In August 1865, Lister applied a piece of lint dipped in carbolic acid solution onto the wound of an eleven year old boy at Glasgow Infirmary, who had sustained a compound fracture after a cart wheel had passed over his leg. After four days, he renewed the pad and discovered that no infection had developed, and after a total of six weeks he was amazed to discover that the boy's bones had fused back together, without the danger of suppuration.

The stamp has not scanned well; its catalogue description says it is indigo, black and grey. The tube snaking down the centre of the stamp should be indigo (red).
Carbolic acid and related phenols can be derived from coal tar - this reminded me of this set of stamps issued on 25 Jan 1978.

I believe I have shown the 'coal' stamp in an earlier Sunday Stamps post.
