For compound expressions please use the exponent rather than the sign . Write 0.05 not .05. Displayed equations should be numbered at the right hand margin. Short formulae should be left in the text where possible, but should not usually be more than one line high. Line drawings should be supplied at double the intended size.
Illustrations are to be numbered consecutively.
They should not be inserted in the pages of the manuscript, but supplied separately with the typescript. Lettering should be unambiguous and should be typed or stencilled either in Indian ink or Letraset, large enough for any necessary reduction. Typewritten or handwritten annotations are not acceptable. Illustrations must be presented as high quality laser printed computer output. Legends for illustrations should be typed on a separate page.
