 of which need a change of host, — depends upon the conditions of each of the two 

 hosts. He formulates three laws: "(1) The metaxenous disease will not continue 

 to exist in a locality unless both hosts are numerous enough; (2) a small increase 

 of the munbers of one of these hosts above this point which may be called the critical 

 point, may cause a severe epidemic among the other species of host; (.3) the disease 

 will tend to reach a limit depending on the constants."
