Dr. Jenner’s Experiment

  “March 28th, 1797, I inoculated this girl and carefully rubbed the variolous matter into two slight incisions made upon the left arm. A little inflammation appeared in the usual manner around the parts where the matter was inserted, but so early as the fifth day it vanished entirely without producing any effect on the system.” —Edward Jenner (1749–1823). “The Three Original Publications on Vaccination Against Smallpox.” Portrait of Edward Jenner, painted by James Northcote in either 1803 or 1823

In Proportion

“It is essential for you to remember that the attention you give to any action should be in due proportion to its worth, for then you won’t tire and give up if you aren’t busying yourself with lesser things beyond what should be allowed.” (Marcus Aurelius)
