SUMMARY1 An investigation has been made of the distribution of yolk over the fleece of Welsh sheep. 2 The suint content of the wool is relatively low on the back and high on the flanks and breast. The distribution of suint over the back appears to vary in a random way. 3 The pR of water extracts generally runs parallel with the suint content of the wool, although the correlation is not mathematically significant. The reaction is approximately neutral on the back and alkaline on the flanks and breast. 4 The grease content is fairly uniform over the back and flanks, but the wool on the breast contains relatively less grease. 5 These results are discussed in relation to Holdaway and Mulhearn's theory that sweat content is an index of susceptibility to blow‐fly attack.
