The (h'j^ree ot imninnitx ])roduced hy t lie Aust ral ian \aecine is 

 und()ul:te(lly a y'ood one. \Ve have tested inoeuhiled animals with 

 v;iri()us quantities ot virulent anthrax <>'ernis. and have tound. as in 

 llie case of our Spore vaccine, that, ex'cejjt w liere very lar^c (juantilies 

 were ust'd, the animals resisted tlie infecti(ni. 



Il is ini|H(ssil)le to sa\ how lon^' animals inoculated with thi' 

 Australian \accine remain immune. The (Uily wa \ to estal)lish this 

 is to wait for periods iiii to a year and lon;4'er and then to test the 

 animals a^ain. 



One drawhack of the Australian \accine i> the smallness (d the 

 dose. Cattle should receive two-fifths of a cubic centimetre, and 

 lunses, slieej), and eoats one-fifth. This nmkes the o])eration rather 

 difficult for the farmer. The price was quoted to us as working out at
