Diary of Olivia Salamanca

September 4, 1911

Rejoice at the fact that I shall be the first one in the P.I. to be subjected to the use of tuberculin in tuberculosis. I am glad, because I afford the best chances for its actions to be carefully noted. If tuberculin proves effective in the care of T.B. by the experiment made on me, I would feel as if I have rendered a public service to humanity. Should it fail (there is no occasion for such thought, for I would know in time whether it is doing me good or not) then I shall be glad also for it would save many from its dangers. Help me, Jesus dear! And may the experiment be carried out successfully, so that thousands of useless lives may be made useful by it.
