No one can write perfect English and keep it up through a stretch of ten chapters.

It has never been done.

It was approached in the "well of English undefiled"; it has been approached in Mrs.Eddy's Annex to that Book; it has been approached in several English grammars; I have even approached it myself; but none of us has made port.
Now, the English of Science and Health is good.

In passages to be found in Mrs.Eddy's Autobiography (on pages 53, 57, 101, and 113), and on page 6 of her squalid preface to Science and Health, first revision, she seems to me to claim the whole and sole authorship of the book.

That she wrote the Autobiography, and that preface, and the Poems, and the Plague-spot-Bacilli, we are not permitted to doubt.
