duced. When giving instructions for reduction linear measurements are under-
stood ; thus, " half-size " means reduce to half the length and breadth, not half the
area. A photograph should not be rolled up, nor pinned, and should always be
packed flat. A complete list of plates and figures should always accompany the
paper.

16. Line drawings should be made with clear black lines on smooth white paper,
preferably Bristol board. Rough paper should be avoided. Care should be taken
that all the lines are drawn firmly; scratchy or grey lines, produced by the ink
being thinned down, are not permissible. Drawings should be larger than the re-
quired size. All lettering should be neatly and clearly put in, care being taken to
make all lettering sufficiently large to stand reduction.

17. For half-tone work, copy should be made on glossy silver paper and of the
same size or larger than the size required.

18. For three-colour work, copy may be oil-painting, water-colour, coloured
photograph or coloured transparency, and larger than the size required. In pre-
paring copy, one should use only the primary colours, in any combination, as only
inks of primary colours are used in printing. Originals can be enlarged, if neces-
sary, but this should be avoided if possible.

19. For detailed instructions regarding preparation of illustrations, it would be
of advantage to refer to Mr. C. M. Hutchinson's article on " Photographic Illustra-
tions " in the Agricultural Journal of India, Vol. XI, Pt. 3, July 1916, and Mr. A. W.
Slater's paper on " The Preparation and Reproduction of Scientific Illustrations "
in the Proceedings of the Third Entomological Meeting, 1919, which has been reprinted
as Bulletin No. 114 of the Imperial Institute of Agricultural Research, Pusa.
