Text Appearing Before Image: 1980 Notes 459 Text Appearing After Image: Figure 1. Male Moose skull with a peruke. of the effects of both hypogonadism and castration in other cervids (Taylor et al. 1964; Murphy and Clug- ston 1971; De Martini and Connolly 1975). Toxic substances have been suggested as the cause of testicu- lar atrophy (Thomas et al. 1964; De Martini and Connolly 1975), but to my knowledge these sugges- tions have not been confirmed. Accidental castration may have occurred in the cases of the Moose described. Literature Cited Bubenik, A. B., O. Williams, and H. R. Timmerman. 1977.
