 srouul scat in front of us. At the first glance I whispered 

 to Kitty, " I think that is 1 )r. Whewell ! " Presently I asked 

 a man near us who it was, and he replied, 4< The Master of

On Thursday, business opened at eleven by addresses by 

 the chairmen of the several sections. There is no general 

 session. We selected Huxley's, in the department of zo- 

 ology and botany, and we were fortunate, for it was a most 

 admirable address explanatory of the scope and purposes 

 of biology. I meant to have got his classification, and shall

 Owen is an old grandmother, whose business is to nurse her

 but it was the foundation of his philosophy. While I was 

 with him the other day Spencer started the point of using 

 the term " persistence of force " rather than " conserva- 

 tion." They had quite a spurt over it, Tyndall declining to 

 meddle with the words he found. But to-day Huxley used 

 the term " persistence of force." The experiments last night 

 were, first, testing oxygen and hydrogen separately ; second,
