 blackbird and thrush at any and all times of the year," 

 and goes on to say that he "should expect to find these 

 embryos in the blood of one out of every third or 

 fourth blackbird or thrush which he examined." He 

 has also frequently found them in the starling. 



Colonel Wyville Thomson has also recorded in 

 the same Journal his having repeatedly found these 

 organisms in the blood of the jungle crow of India 

 {Corvus 7fiacrorhy?iais), and both this observer and Dr. 

 Coles have in addition found other well-known bodies 

 (Haemosporidia and Trypanosomes) along side them. 



One would imagine that these pathologically im- 

 portant organisms would be comparatively common 

 among the cosmopolitan collection of birds in the 

 Zoological Gardens, but like the avian septicaemia 

 characterized by the formation of cheesy nodules, and 

 found so frequently in cage and aviary birds, (and 

 even occasionally in wild birds), by Dr. Clarke and 

 myself, they do not figure in the pathological Report 

 of the Society. 



THE MARCH OF SCIENCE :— A gentleman who 

 within my own knowledge lays claim to being what he 

 calls a "science doctor," and who appears to be so 

 full of "science" that he has some difficulty in accepting 

 what passes for science among mere ordinary Doctors 

 of Science or Medicine, has lately been telling the 

 readers of a certain paper that it does not matter 

 whether their birds are pronounced to have died of 

 septic enteritis or enteric fever, so long as they have 

 died, and moreover that whether we speak of " lung 

 diseases" — there are several of these, I may say — as 

 consumption or not is of no moment. At first sight
