The Mosquito.-the mosquito is a common carrier of yellow fever and malaria or “chills and fever” as it is sometime spoken of by the public.  Malaria is caused by a tiny parasite which can only be seen by the microscope in the blood of man and the mosquito.  It lives and multiplies in the blood of an individual suffering from the disease.

It definitely is interesting to see that they do have a pretty good understanding of what malaria was even though the microscope was still relatively new back at time of publication of this book.  Just a short description of the potential of this little insect that causes people so many problems.  Malaria medicine and running water have helped people get away from these critters.  Many colonial settlers  in Africa tended to locate themselves close to rivers and streams to be close to running water.  This was a formula that worked in colder climates where mosquitos were not as dangerous, but in the tropics this put them in the danger zone for malaria.  They literally settled in the mosquito breeding areas.

Well and running water deliver waters into the homes around the world from the ground to the faucet helped people move away from the proximity of these danger areas, but there are still many people stuck in the original settled areas.
