Experimental Hybridization,s of reproductive failure in man and animals. It is not within the scope of this paper to review the extensive literature on mammalian hybrids; those interested are referred to the comprehensive check list by Gray (1957). Nor is it the intention here to examine the problems of hybridization in relat

Sterility and Fertility of Interspecific Mammalian Hybrids,-breed. More specifically, hybrids are the results of crosses between different animal species and best known for their utility are the mule and the hinny, the offspring of horse × donkey matings. Hybridization between different mammalian species has been described to occur in nature but much more c

Because a malformation like polydactyly can be harmless, while an invisible “inborn error of metabolism” like galactosemia can be lethal, I have extended the title orginally assigned to me to permit inclusion of defects other than

Fetal Infections in Man,estimate the relative frequency with which infections are responsible for wastage of human lives prior to so-called viability. The morphological characteristics of the abortus are often unrevealing, although decidual necrosis and inflammation are almost invariably found. Appropriate bacteriological

Whether transmission occurs only during the acute or also the chronic stage of maternal infection, and whether only single or also multiple pregnancies can be infected is still now being debated. Fetal infection has been observed spontaneously also in sheep, pigs, dogs and mi
