From J. V. Carus   13 September 1877

My dear Sir,

Although I am afraid that it will be too late for the first edition of your new book on different forms of flowers, yet I give you a short list of some few Errata, as usual.¹

p. 36. l.15 dele stop (,) after “plants”.

p. 43. l.3 from bottom (text) read “plants” instead of plant.

p 53. l.8 from bottom (text) read “form” instead of forms.

p. 162. l.12 from bottom read “acts” instead of “is”.

p 196 l.17 (Class III) read “stamens”, not stamen

p 205. Class III read “from own-form mid-length stamens” instead of shortest stamens

“Shorter” would do perhaps; but the terms “longest”, “mid-length” and “shortest” refer to three different definite lengths; and in accordance therewith, there are no shortest stamens in the short-styled form.²

In different places of the book you mention “divisions of the micrometer”. Although you speak mostly of relative lengths or distances, yet I venture to suggest, that it would be perhaps still more clear, if you would give also an absolute measure May I therefore ask you, what these divisions are, $\frac{1}{100}$^ths of an inch or
