Many thanks for your friendly letter.— I am away from home, but have written there to send you the 4 first sheets just printed, & tomorrow I will send 3 others.—¹ You shall have remainder as soon as printed. The book is a very dull one, but I think has some value. All the first chapters are mere record of experiments.—The latter chapters alone worth reading. Your news about the Album deeply gratifying to me, but Häckel says I ought not to have been told.²
