| Title | Appendix, 'Correction of an error of observation in part XIX of the author’s memoirs on the organisation of the fossil plants of the coal measures' by William Crawford Williamson |
| Date | 1894 |
| Description | Williamson writes: 'During the past two or three years we have acquired a much more accurate knowledge than we previously possessed of the structure of the leaves of the Lepidodendroid plants of the Coal Measures; and my last memoir, published in vol. 184 (1893) of the Philosophical Transactions, contains some new and not unimportant details on this subject. These facts were obtained from some finely preserved specimens of Lepidodendron Harcourti and of a Lepidophloios recently added to my cabinet. But the value of these observations was seriously vitiated by an apparently small but very fundamental error into which I had fallen, an error which cannot be left uncorrected without misleading some of the palaeontologists who honour me by consulting my writings on these subjects.'
