Letter from Howard Walter Florey to T A Margerison, Scientific Editor, New Scientist, Fulwood Place, High Holborn, London Thanks for invitations to write article about work on cephalosporins - most of this work has been done by E P Abraham and G G F Newton and is mainly chemical - he should not have been able to write article in any case - says neither Abraham nor Newton feel able to do this in foreseeable future. 6 July 1960
