In seven years Mrs.Eddy taught, as she avers, over four thousand students in it.

(Preface to 1902 edition of Science and Health.) Three hundred times four thousand is--but perhaps you can cipher it yourself.

I could do it ordinarily, but I fell down yesterday and hurt my leg.

Cipher it; you will see that it is a grand sum for a woman to earn in seven years.

Yet that was not all she got out of her college in the seven.
At the time that she was charging the primary student three hundred dollars for twelve lessons she was not content with this tidy assessment, but had other ways of plundering him.
