Copy letter from Herbert Rix, to Messrs Clay & Sons, University Press, Cambridge The Catalogue Committee yesterday instructed Rix to set up in type and circulate within a week the specimen copy which had been prepared for the Subject Index to the 'Catalogue of Scientific Papers'. The style of type chosen is that enclosed herewith [not attached], arranged in three columns, and he thinks the whole will run to a sheet or a sheet and a half. Rix is sending the copy by passenger train this afternoon. Asks if the Messrs can let them have 50 copies by this time next week. Instructions are provided for printing. 23 June 1893
