This is a reproduction of a graph produced by the Animal Research Station, Wallaceville, to illustrate the efficiency of fine particle phenothiazine against worms in sheep. TARTAN FENODREN liquid has a median or average particle size by weight of 3 microns (I/8000th of an inch!), and the above graph shows the high order of efficiency of phenothiazine within this size range. When you get down to comparing these fine sizes, a microscope is necessary to compare the degree of fineness. However, the following diagram shows the particle size of some everyday materials on the same scale as typical particles of TARTAN FENODREN. For example, flour, fine by normal standards, has a particle size which would not be classed as a satisfactory average in an efficient phenothiazine product. A: Particle of typical flour. B: Particle of face powder. C, D & E: Typical size range of Tartan Fenodren particles. escjsqesis] FENO D R E N phenothiazine North Island Distributors: , Summit Products Ltd. ■ South Island Distributors: A. S. Paterson & Co.
