DISCUSSION. 247 



bring order out of chaos only by systematic study. The variations in 

 culture of Streptothrix are greater than in any other organism. It must 

 be remembered that none of these Streptothrix infections are inflam- 

 matory processes. They are destructive without much inflammation. 



As to actinomycosis, I think perhaps it had better be included in the 

 list of the Streptothrix infections. 



Doctor Atkinson. — In eonnnection with Streptothrix infections, I 

 should like to ask Doctor Musgrave and Major Hooton if there is any 

 similar infection in horses in their respective countries ? We have some- 

 thing approaching it in China. 



Doctor Musgrave. — So far as I know there has been only one case 

 reported in a native animal of the Philippines. I have seen it in Aus- 

 tralian and American horses. 



Maj. A. Hooton, I. M. S., Rajkot, Eathiawar, India, delegate from 

 the government of India. — I will state in reply to Doctor Atkinson's 

 question that the treatment I adopted in that particular ease was the 

 removal of the growth. 



As regards the question of Streptothrix infection in animals, I made 

 inquiries in Bombay and was told that perhaps two or three cases of 

 mycetoma in animals are encountered in a year.
