 ,—I can now tell you (what I wanted to do when you sent me that text-card, but felt I could not say it to two listeners, as it were) why that special card is one I like to have. That text is consecrated for me by the memory of one of the greatest sorrows I have known—the death of my dear father. In those solemn days, when we used to steal, one by one, into the darkened room, to take yet another look at the dear calm face, and to pray for strength, the one feature in the room that I remember was a framed text, illuminated by one of my sisters, "Then are they glad, because they are at rest; and so he bringeth them into the haven where they would be!" That text will always have, for me, a sadness and a sweetness of its own. Thank you again for sending it me. Please don't mention this when we meet. I can't talk about it.

The object of his edition of Euclid Book V., published during the course of the year, was to meet the requirements of the ordinary Pass Examination, and to present the subject in as short and simple a form as possible. Hence the Theory of Incommensurable Magnitudes was omitted, though, as the author himself said in the Preface, to do so rendered the work incomplete, and, from a logical point of view, valueless. He hinted pretty plainly his own preference for an equivalent amount of Algebra, which would be complete in itself. It is easy to understand this preference in a mind so strictly logical as his.
