450 MUSGRAVE, CLEGG, AND POLK. 



is apparently of the same stock as that from which all the cultures in the 

 London laboratories are derived.") 



3. 8. madv/rcB Vincent. (This culture was sent to us by Professor Binot of 

 the Pasteur Institute in Paris.) 



4. 8. madurce Vincent. (This organism was isolated by Dr. R. P. Strong 

 from a case of the pink variety of mycetoma in India, and the culture has been 

 given by him to us, for study. 



5. Btreptothrix of human aetinomyces. (From Binot of the Pasteur Institute 

 in Paris.) 



6. Btreptothrix of "farcin de ooeuf" "A". (From the late Professor Nocard 

 through Binot.) 



7. B. nocardii. (From Foulerton who writes that '"'this culture was given to 

 me by Nbcard some six years ago.") 



S. 8. eppmgeri "A". 



9. 8. eppingeri "B". (Both of these cultures are from Foulerton who 

 writes as follows: " 'A' is a descendant of what I believe to have been Eppinger's 

 original culture, 'B' a culture isolated by myself from a case which has not yet 

 been published in detail. I have examined also a third culture of this species 

 obtained by Dr. McDonald from a third ease (The Scottish Medical and Surgical 

 Journal, 1904). All three strains evidently belong to the same species." 



10. 8. caprw Silberschmidt. (Received from Professor Silberschmidt of Zurich 

 through Binot.) 



11. S. cams Levy. (From Professor Levy of Strassburg through Binot.) 



12. iS. chalcea Foulerton. (Received from Foulerton who writes that this is 

 a saprophytic species isolated by him from the air.) 



The following cultures have also been received, but failed to develop on 

 transplantation : 



S. madurce Vincent. (Furnished by Professor Vincent of the Val du Grace, 

 Paris. ) 



jS. madurce. (From Legrain de Bougie through Binot.) 



Btreptothrix of bovine Actinomyces. (From Binot.) 



Btreptothrix of "farcin de boeuf" "N". (From the late Professor Nocard 

 through Binot.) 



Btreptothrix of Eppinger ("A") and (Kl). (From Binot.) 



Streptothrix of Deci. (From Binot who writes regarding this culture that 

 "it was isolated by Deci in the Argentine Republic from a human case resembling 

 tuberculous meningitis." Binot further states in his letter that all the cultures 

 which he has forwarded to us were received by him directly from their authors). 



Btreptothrix "32". (Received from Foulerton who writes that this or- 

 ganism was isolated by him from a kidney removed from the living patient 

 by operation; the organism was demonstrable in sections of the kidney and was 

 present in large quantity. It is briefly referred to as S. hominis HI in the 

 Lancet (1906), 1, 970. "This organism resembles closely some of the apparently 

 purely saprophytic species, and the infection in- the ease was probably primary 

 in the lungs." 



Streptothrix isolated from a case of mycetoma by Dr. Chaterjee of India. 



Dr. Homer Wright states, in reply to a letter regarding cultures of Actino- 

 myces and his "Hyphomycete," that he no longer has cultures of these organisms. 



A comparative study under conditions as nearly alike as possible has 

 been made of all these strains, with due consideration of their morphol- 

 ogy, biology, and pathogenic character. All of them, to obviate as
