I have mentioned before that, as Lazear and I, vaguely hoping

to find malarial parasites in Carroll"s blood, sat looking into
our microscopes that morning, the idea that the mosquito was
what brought him down gradually took hold of our minds, but as
our colleague had been exposed to infection in other ways, by
visiting the yellow fever hospital 'Las Animas,' as well as the
infected city of Havana, it was necessary to subject that same
mosquito to another test and hence the inoculation of Private
Dean, which is described in the opening chapter of this
history
