Some reconstruction of the fran7cis 7gigafton Laboratory having taken place, it seemed desirable to provide the workers associated with it with a direct channel of publication of their own, in which their more extended memoirs should appear. It is hoped that the present series may be issued at short intervals. Subscribers should notify their intention of taking in the memoirs as they are published to Messrs Dulau Co. Requests to exchange with similar publications, with archives and journals dealing with demographic and sociological problems, or with census reports, should be directed to The Editor, Eugenics Laboratory.
