but how they begin now we can pretty thoroughly un-

it is not using it. To use it understandingly, we must 
work with it overand over again. We must have the most

we must be thoroughly au fait with its use in every branch 
of science. Then working with the microscope we find the 
following things. 
We look at a mass of water, such as is recently distill- 
ed, and we see that it is transparent, that is to say we do 
not see anything in it more than we do when examining
