The purpose of this bulletin is to explain by description and illustration just how this is done. The sexes are distinguished by pattern of the white head spot, leg colour and by shade of black colour in the down. ... The subject will be dealt with under four main headings, namely, The Head Spot, Leg Colour, Shade of Black Down and the Practice of Sight Sexing"--p. [3].
