It is some eight or ten weeks ago since I had the privilege of enjoying the hospitality of your genial secretary, and in an unguarded moment, doubtless stimulated by my host's genial company, I half committed myself to giving a further communication on this subject, and he committed me for the other half. The truth is I have no paper to read. I have very little further to add to what I have said before, and I have certainly nothing further of note worth publishing. At the same time I very gladly welcome the opportunity of reviewing the position, so far as it appears to me in the light of the further available records on the subject in the last two years.
