A few weeks later, Wherry had heard of my desire to bring 1 S S 

 with me, at a small salary, a research slave out of Oakland. 

 He had also heard that physiology in Cincinnati had no 

 money for such purpose. Said Wherry (June 10, 1910) : 



... If Pres Dabney cannot find the money to place the sug- 

 gested assistant in your department, nominate him for pathol- 

 ogy, let us pay the bill, and use him in physiology. I have 

 spoken to Woolley about this . . . Now as to the reason why 

 I have not written for so long: I have been working like the 

 devil on some cases of pernicious anemia that Dr Forchheimer 

 got for me, and on one fatal case we posted at the hospital. Of 

 course my work is on etiology from the infectious point of 

 view. I have argued thus : 



1 Repeated injections, continued over a long period of 

 time, of a hemolytic agent, e g ricin, produces the ana- 

 tomic and physiologic picture of pernicious anemia. 



2 The toxine (?) of Bothriocephalus latus absorbed from 

 the intestinal tract produces the picture of so-called 

 "cryptogenetic" pernicious anemia in a considerable 

 percentage of cases. 



Might it not be possible that these "cryptogenetic" cases 

 are due to hemolysin produced by some microorganism in the 

 intestinal tract — bacterial or protozoan? I have been looking 

 for everything and have collected and compared a mass of 

 stained preparations and cultures. You can imagine that I was 

 somewhat excited when the contents of the ileum and colon 

 (from the fatal case) when plated in agar mixed with de- 

 fibrinated rabbit's blood, showed the presence of a very large 

 percentage of bacteria whose colonies were surrounded by a 

 wide zone of hemolysis. 



However, I am beginning to cool off, now that I have studied 

 some normal controls and cases other than pernicious anemia. 

 But I still hope to find some specific differences. In any case, I 

 will have learned something about the hemolyzers of the in- 

 testinal tract. I have no intelligent assistance whatever and 

 the preparation of media etc takes much time. Most of the 

 young fellows are afraid to stick to anything so time-con- 

 suming as bacteriology. 



As you will see from the paper I send along, Dabney got
