Copy letter from Herbert Rix, to Messrs Dulau & Company, 37 Soho Square, W. Asks for an explanation of the very high price given for the 'Annales de l'Ecole Normale' on the enclosed invoice [not included]. It would cost them three shillings to have it sent direct and they would receive it more promptly, and Rix notes that the reason they use Dulau & Company is to save expense. Rix asks that they write to explain the meaning of the phrase 'expenses on'. 31 January 1889
