28 THE MOSQUITO ORIGIN OF DISEASES 



during the epidemic invasion, its shifting lines of infec- 

 tion and gijratori} movements suggest to the imagination 

 the attributes of insect life.'' 



Then in still more recent times we find King ' in 1882 

 tabulating the facts in support of the mosquito origin 

 of malarial disease, showing hosv the word "Miasm" 

 can in all cases be replaced by the word " ^Mosquito." 



Again, later, tlie name of Dr. Charles Finlay" is 

 linked up with the mosquito origin of yellow fever. He 

 did much to direct the recent researches on yellow fever 

 to the Stegomyia as the transmitting agent in that 

 disease. 



AVorking in a totally different direction, in a direc- 

 tion which had already been followed up and was well 

 known to the scientific world, namely, the relationship 

 of the lower animals to man in the transmission of 

 human disease, conclusions were arrived at which 

 demonstrated that it was possible that even a small 

 insect like tlie mosquito could act as an intermediate 

 host or carrier of disease organisms. 



It had already been pro^■ed that improperly cooked 

 meat containing the encysted larvae of the JVichina 

 spiralis was capable of producing a very severe disease 

 in man known as Trichiniasis. Tlianks to the re- 

 searches of ^'irchow and others this disease, which at 

 one time caused considerable mortality, was finally 

 banished by instituting a proper system of meat inspec-
