[Favre (1), writing in 1873, states that a railway accident is said to have been caused by colour-blindness in England several years before, but that he had no exact particulars. He does not mention the source of his information. This case is so meagre that, although I mention it in its chrono- logical order, I do not propose to count it in the series. It might possibly be the same as Case 26 below.] Case 24.—In the same paper Favre states that three years earlier (i. e., in or about 1870.—E.

In the summer of 1876 a col- lision occurred on the Finnish Railway between Helsingfors and Tawastehus, which was caused by a colour-blind pointsman who had held up the green instead of the red lantern to the approaching train. I have tried to obtain original information about this case, but without success. Case 26.—Haynes Walton (23) gives the following case in a letter headed Colour-blindness, on p. 8 of The Times for January 3rd, 1877: Colour-blindness may be acquired. This is very rare compared to its existence as a congenital defect, and not generally known. A few years ago I was investigating colour appreciation, and the first instance of the acquired defect that came to my knowledge was in the person of an engine-driver. This man confessed, after an * Perhaps a misprint for Biickeburg, not far from Minden.—E. X.](https://iiif.wellcomecollection.org/image/b2128782x_0034.jp2/full/800%2C/0/default.jpg)
