Extract

A total dose of 30 gm. of phenothiazine, given as tablets in one dose of 15 gm. and three of 5 gm. to three goats and six sheep known to be worm-free, had no effect on the weights of the animals in comparison with equal numbers of worm-free controls, over a period of 15 weeks from the first dose.

It is concluded that weights can validly be used as a criterion of anthelmintic efficacy; they not only constitute an obvious economic criterion, but also are statistically more sensitive than egg-counts when subjected to analysis of covariance.
