The lack of material at Quemados caused us to remove our field
of action to Havana, where cases of yellow fever continued to
appear. We met almost every day at 'Las Animas' Hospital, where
Lazear was trying to infect his mosquitoes, or now and then I
performed autopsy upon a case, and Carroll secured sufficient
cultures to last him for several days of bacteriological
investigation.
