把这一句，留给此刻的你
The value and utility of any experiment are determined by the fitness of the material to the purpose for which it is used, and thus in the case before us it cannot be immaterial what plants are subjected to experiment and in what manner such experiment is conducted.
任何实验的价值和效用都是由材料对其用途的适合程度决定的，因此，在我们面前的情况下，植物接受什么样的实验，以什么样的方式进行实验，都不能是无关紧要的。
