Page 289 - And though all the winds of doctrine were let loose to play upon the earth, so Truth be in the field, we do injuriously by licensing and prohibiting to misdoubt her strength. Let her and Falsehood grapple; who ever knew Truth put to the worse in a free and open encounter?
Page 531 - I am labouring to lay the foundation, not of any sect or doctrine, but of human utility and power.

The more successful we are in explaining their origin, the more doubt we...
Page 265 - Lazear also experimented on himself at the same time, but was not infected. Some days later, while in the yellow-fever ward, he was bitten by a mosquito and noted the fact carefully. He acquired the disease in its most terrible form and died a martyr to science and a true hero. No other fatality occurred among the brave men who, in the course of the experiments, willingly exposed themselves to the infection of the dreaded disease. A camp was especially constructed for the experiments about 4 miles...
