Space and time relations in the coat of the New Zealand Romney lamb

Abstract

In a recent paper Dry (4) gives an account of the fibre type arrays - the result of an action of two forces - the prenatal check and the reducing of inherent coarseness acting on an undefined substratum which occur on the back (4) of the New Zealand Romney Lamb. Preliminary observations by Dr. Dry and myself suggested that orderly relations existed between the fibre type arrays on the back and britch positions. These observations were extended and a comparative study of the fibre type arrays occurring over the dorsal and dorso-lateral portions of the coat of the Romney Lamb has been made. Their distribution, as one was prepared to find, has proved orderly. Following naturally on this investigation came a study of the proportions of precurly-tip to curly-tip and histerotrich fibres.
