Amputee mice subjected to the stressful conditions of a continually disturbed hierarchy developed excessive louse infestations. These infestations apparently were the result of a reduction in mutual grooming. In contrast, mutual grooming, among amputee mice in stable hierarchies maintained the louse infestation at an essentially nonexistent level. Additional evidence for the stressful conditions in the disturbed hierarchies was an eosinopenia among ♂ mice and an approximate 50\% decrease in the percentage of pregnancies and relative lack of ovulatory activity in ♀ mice, as compared to that of mice in the stable hierarchies.

Sporadic dry gangrene of the ears of white mice, and conditions conducive to its occurrence, are described. The incidence of ear necrosis increased markedly when the mice were subjected to cold and when their ears were traumatized by grooming to rid themselves of lice. Louse infestation alone is not a causative factor in the production of ear lesions. Age and breed of mice were other factors which affected incidence. The lesion is usually not important in the maintenance of colonies but might occur in situations where mice are subjected to stress.

Studies of louse populations on partially disabled mice kept individually to prevent mutual grooming have demonstrated that after initial exposure to the parasite, subsequent populations were limited because of development of acquired resistance by the mice.

During these experiments it was established that a long period of intensive exposure is required for full development of the resistant state. Further, based on a limited period of observation, the inhibitory function appears to be limited to the exposed site rather than generalized over the entire body.

Although detritus that accumulates in a region heavily infested with lice was not a major factor in the resistance to reinfestation that was noted, it could not be eliminated as a minor one.

The successful feeding of larval ixodid ticks on louse-resistant mice in a single experiment indicated that the resistance is probably specific for lice.
