Report on Examination in Colours for the 15 Months ended 31st August 1894.

SIR,

TO THE PERMANENT SECRETARY, BOARD OF TRade,

STATISTICAL TABLES for the 15 months ended 31st August last relative to the examination in colours of candidates for masters' and mates' certificates of competency, and of other persons belonging to the mercantile marine, are herewith submitted in the usual form.

As will be seen from Table II., the number of persons who failed to pass the tests during the period under review was 81; 45 of these had applied for certificates of competency, and 36 for examination in colours only.

This Report is the last which will deal with the system of examination by means of coloured cards and glasses, as a new system of tests, based on the Report of the Committee of the Royal Society on Colour Vision (Parliamentary Paper, C-6688, 1892) was brought into operation on the first September last; it covers a period of 15 months, i.e., from the date of the previous Report to the date of the introduction of the new system.

The new examination consists of three parts:-(a) The Form Vision Test, which is intended to ascertain whether a candidate has good or bad sight; (b) the Colour Vision Test, whether he can distinguish colours correctly; and (c) the Colour Ignorance Test, whether he can name colours correctly. For Form vision the candidate is examined by Snellen's letter test, or, if he cannot read, by the "Dot" test. In the former case the candidate is required to read letters of different sizes arranged in rows on a sheet placed at a distance of 16 feet from him. In the latter case the candidate is required to answer questions with regard to the number and position of dots arranged in different lines and groups on a sheet placed a distance of 8 feet.

The Colour Vision Test is conducted by means of Holmgren's wools. The candidate is required to select from a general heap of wools of different colours those skeins which in his opinion match with one or the other of three test skeins of the colours of (1) light green; (2) pink or light purple; and (3) red.

The object of the Colour Ignorance Test is to ascertain whether the candidate knows the proper names of colours, so as to ensure his being able to name correctly the red, green, and white lights. This test is introduced mainly to meet the case of foreign seamen serving in British ships.

Full details of the new method are given in the Parliamentary Paper already referred to.
