Photographs: Photographs should be sufficiently high quality with respect to detail, contrast and fineness of grain to withstand the inevitable loss of contrast and detail inherent in the printing process. Please indicate the magnification by a rule on the photograph. Colour figures: there is a special charge for the inclusion of colour figures. Figure legends: these should be on a separate, numbered manuscript sheet grouped under the heading” Legends “on a separate sheet of the manuscript after the References.
