William Clowes [printer for J. Murray] estimates that Variation will come to a first volume of 648 pages and a second volume of 624 pages – which is too much for volumes the same size as Origin. Murray proposes a larger size.
My Dear Sir
Vol I. 648 pages post 8
same size as the origin of Species—independant of contents Preface Index
& any addit
This is clearly too much for volumes of that size—& I propose
therefore—with your consent to substitute the larger (Demy) 8
On hearing from you the Printer will be set to work
I am My Dear Sir | faithfully yours | John Murray
Ch. Darwin Esq
