Copy letter from an unknown correspondent, to Mr D Nutt, 270 Strand 'In answer to yours of yesterday, our only reason for stopping the "Acta Mathematica" is that we exchange publications with the editor, and it is only by an oversight that the purchase was not stopped a year ago. The other publications are of course to be continued, & we are always open to consider new works in Mathematics or Physics sent on appro. [approbation] though our allowance for ^purchase of^ new books is not large'. 16 April 1894
