The experiments with the use of unspecific hosts gave positive results; a day after the removal from cow, the lice were found to take the blood of man, mouse, guinea pig, rat and cat and survive longer than starving ones (table 1). The highest survival rate was exhibited by lice fed on human blood (table 2). The bites of H. eurysternus were mostly painless, the sensation of pricking appearing in the next days of feeding.
