"Y: I suppose you also deem it a crime to drink, as you destroy myriads of animals in the water of every draught? Z: I consider this an evil, but not a crime, because I do not cause or wish them to be there, and would assist them to escape if possible. They have no more claim to the water than I have; and we know so little of the nature of these animals, that we are not even sure that they die when the water is drunk; the very fact of their being there is concealed from us, and but for the microscope we should never have known it. I however consider it wrong to waste water in anyway which may injure the animalcula."
