Joseph Lister efficacy of carbolic acid when applied directly to wounds. Therefore, 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 a seven-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
Name-letter effect English, German, French or Spanish revealed a name-letter effect for the Roman alphabet as well as for Cyrillic.

In a follow-up study Hoorens, Nuttin, Herman and Pavakanun tested the strength of the name-letter effect among elementary-school children, in a cross-sectional experimental design involving Flemish and Hungarian second, fourth, and sixth graders. Instead of finding the name-effect to decrease with age as might be expected, they found it increased, thus proving that mastery pleasure is not the principal cause. They also investigated name-letter effects in bilingual Thai
