 plenty on the hands of those who attended to the 

 cleaning etc. Any one with even the most elementary 

 knowledge of bacteriology knows so much, and every 

 one with the slightest experience of attending to a 

 bird room can readily call to mind a hundred different 

 ways whereby he would unconsciously transfer germs 

 to all the other cages from the one in which the}^ had 

 first effected a lodgement. That foreign birds, both 

 great and small alike, are susceptible to the particular 

 form of septicaemia that the Canaries were dying of 

 is equally beyond doubt. Post viorte7n investigations — 

 even on the part of those who so constantly mistake 

 the disease for tuberculosis — have decisively settled 

 that point. Immunity therefore cannot be pleaded 

 any more than that there was no access of infection. 

 But it looks to me as though the escape from sickness 

 and death was ver}^ intimately connected with the 

 absence of ^%% from their dietary, and that the wliole

 confirmatory of the views held by Dr. Clarke and 

 myself.

 was going on until a very short time before they were 

 hatched. I then saw that both pairs had two little 

 white eggs. One pair hatched the two, the other pair
