JUNE 14.] THE NEW ZEALAND GAZETTE. 1691

“Normal vision” is defined, for the purpose of these regulations
as ability to read correctly nine of the twelve letters in the sixth line
and eight of the fifteen letters in the seventh line, of a test-sheet
placed in a good light at a distance of 16 ft. from the eye.

The candidate will have the option of using either eye separately
or both eyes together.

5. Spectacles not allowed.—During the examination for form
   vision candidates must not be allowed to use spectacles or glasses of
   any kind, or any other artificial aid to vision.

6. Method of Testing.—The test-sheets should be hung on the
   wall, in a good light, but not in direct sunlight, at a height of 5 ft. or
   6 ft. from the ground. The candidate should be placed at a distance
   of exactly 16 ft. from the sheets, and exactly opposite them. This
   distance should be carefully measured, and should never in any
   circumstances be varied.

One of the sheets should then be exposed, and the candidate
should be asked to read the letters on each sheet, beginning at the
top and going downwards. Any mistakes which he makes should be
carefully noted. If then it is found that he has read correctly at
least nine letters in the sixth line and eight letters in the seventh
line of a sheet, the candidate may be considered to have normal
vision, and should be marked “Passed” in the appropriate column
of the form of application (Exn. 2 or Exn. 2B, as the case may be).

7. Passing or Failure.—If at the conclusion of the test the
   candidate is found to reach the required standard he may be con-
   sidered to have passed, and the Examiner should proceed to test
   him for colour vision. If the candidate fails to reach the standard
   required for the certificate entered for he should be tested with at
   least four sheets, and the Examiner should fill in a Form Exn. 17B,
   and should forward it with any remarks he may wish to make, to
   the Principal Examiner for his instructions as to whether the can-
   didate is to be regarded as passing or as failing in form vision.

8. Lower Standard required in certain Cases.—Candidates who
   are in possession of certificates obtained before the 1st January, 1914,
   may be regarded as passing in form vision if they can read correctly
   with both eyes at least five of the eight letters in the fifth line of a
   test-sheet.

9. Tests to be varied.—The Examiner should take care, by
   varying the order of the test-sheets and by every other means in his
   power, to guard against the possibility of any deception on the part
   of the candidate.

10. Result of Examination to be reported.—The result of every
    examination in form vision should be reported, in the case of a candi-
    date for a certificate of competency, to the Marine Department on
    Form Exn. 2, and to the Principal Examiner of Masters and Mates
    on Form Exn. 14; and, in the case of a candidate for the sight-tests
    only, to the Principal Examiner on Form Exn. 2B.

II. COLOUR VISION TEST.

11. Apparatus.—A special lantern and a mirror have been pro-
    vided for this test. The lantern should be placed directly in front
    of the mirror, so that the front part of the lantern is exactly 10 ft.
    from the mirror. Care should be taken that the lantern is properly
    placed—that is to say, the lights reflected in the mirror must show
    clearly when viewed through the rectangular aperture on the left of
    the lantern. The Examiner should always satisfy himself that these
    conditions are fulfilled before commencing the examination.

12. Darkness Adaptation.—It is essential that a candidate should
    be kept in a room which is either completely or partially darkened for
    at least a quarter of an hour before he is required to undergo this test.

Before the examination commences the Examiner must satisfy
himself that the room in which it is conducted is so darkened as to
exclude all daylight.

13. Method of Testing.—The lantern supplied for the examina-
    tion is so constructed as to allow one large or two small lights to be
    visible, and is fitted with twelve glasses of three colours—red, white,
    and green. At the commencement of the examination the Examiner
    should show to the candidate a series of lights through the large
    aperture, and should require him to name the colours as they appear
    to him. Care should be taken in showing the white light to
    emphasize the fact that the light is not a pure white. If a candidate
    makes a mistake of calling the light “red,” a proper red light
