Henry Twitchin 117 same mental make-up would probably have limited their families fifty years ago. Nevertheless if Dr. Fisher is on the whole correct, civilization can only be saved by a very radical change of opinion and practice. And in particular much of the propaganda of eugenists will prove to have been misdirected. To quote his own words: "The reformer must expect to encounter deep-seated opposition in the classes on which he would naturally rely for an intelligent anxiety for the future of their country." One conclusion is fairly clear. Before the eugenic movement commits itself on the one hand to the further encouragement of the social promotion of infertility, or on the other to subsidizing the breeding of undesirable groups, a really thorough investigation should be made of the causes of differential infertility. There can be no doubt of its existence or of its desirability, but several opinions are possible as to the most hopeful method of combating it. Dr. Fisher's book, then, must be read. But it is not easy reading. It is greatly to be hoped that within the next ten years the sections dealing with evolution and eugenics will both be rewritten in a form which demands less intellectual effort in its readers. Till then it is likely to remain the best discussion of its subjects so far written. [centered scroll-like graphic] Henry Twitchin Some Notes on his Family History By W. T. J. Gun, F.R.Hist.S., F.S.G. I have been asked to make some additions to the account of our benefactor by Major Darwin in the Review for July 1930, and Mr. Leonard Jessop Fulton has very kindly supplied me with information that he collected some years ago in connection with Mr, Twitchin's pedigree. Nothing further has been ascertained with regard to the maternal family, the Lovelocks, nor with regard to the descent of the Northways, to whom the paternal grandmother belonged. It is to be noted, however, that on this side Henry Twitchin possessed a relative, Edward Northway Butt by name, who was in business as a chemist and acquired a considerable fortune. It is probably from the Northway strain that Henry Twitchin's business ability was mainly derived. With regard, however, to the male line descent some interesting facts have been brought to light by Mr. Fulton. The direct ancestry cannot, it is true, be definitely traced back further than Henry's grandfather, Andrew Twitchin. The name Andrew is however significant, as it is frequently found to occur in conjunction with that of Twitchin in various individuals of the seventeenth and eighteenth centuries, yeomen farmers for the most part of men of similar status, residing in Berkshire or its immediate neighborhood. Having regard to this rather uncommon Christian name, and very uncommon surname, there can be little doubt that Henry's grandfather was descended from a certain Andrew Twitchin, of Inkpen in Berks, whose will was proved November 22nd, [end]
