The participation of Australian troops in the Great 
War will almost certainly lead to the introduction, if not 
the establishing, of certain parasitic diseases from other 
lands. We know that many men have returned from New 
Guinea stricken with various forms of malaria*. 
Giardia (Lamblia) intestinalis has caused severe 
diarrheea both in Flanders and Gallipoli (Porter, Proc. 
Linn. Soc. Lond., 2nd March, 1916, No. 317). Ameebic 
dysentery (due to Hntameba hystolytica) occurred at the 
latter locality. Cameron (1916) has recorded its presence 
in a returned Queensland soldier. 
In Egypt there is an abundant human helminth fauna, 
and it is possible that such trematodes as Schistosomum, 
Heterophyces and Paragonimus may be intreduced to 
Australia. Leiper has recently investigated the life 
historyt of Schistosomum hematobium, Bilh., and has
