felt equally important, effective, too, in holding down the ' "71 

 growth of various bacteria. This pleased him, because amoebic 

 dysentery in man always appears as such a double infection; 

 in fact it was by the institution of this * 'symbiosis' ' that 

 Musgrave and Clegg had succeeded in growing the amoebae 

 of dysentery in glass vessels. Via this method, back in 1909, 

 Wherry had isolated a single amoeba from the tap-water in 

 Oakland along with a harmless bacterium. Three years later 

 their descendants were still going strong. Well, here was a 

 protozoan-bacterium mixture much like that always found in 

 human instances of amoebic dysentery. What would emetine 

 do to it? Wherry asked. It killed both parties, he found, but 

 only after many hours of subjection to the poison, when the 

 temperature was right, and if the amoebae had not armored 

 themselves by encystment. 



In the summer he went to the Marine laboratory in Woods 

 Hole where Mother wrote him of her mid-year vacation (July 

 9,1912): 



... I had a bad cook, so rather than try to get another one, 

 we accepted Miss Mitchell's offer to come here [to the hills in 

 Mussoorie]. We had a letter from your sister this week in 

 which she told us of your having been made a full Professor, 

 Will. I want to congratulate you upon this — and to say that 

 we are very glad. You told us that your salary had been raised 

 and we rejoice with you over that too. 



. . . They are greatly in need of rain in the Pan jab. The 

 ferns on the trees show that it is coming. A lady Miss'y of the 

 Church of England died lately of heat apoplexy. There are 

 not so many cases of plague — there never are, when the heat 

 is so great. I send a cutting [on T B prevention] for you to 

 read but I dare say you know it all. Our pastor has been sent 

 to Almora where there is a sort of sanatorium for treating 

 tuberculosis. They give injections & feed patients on certain 

 things. 



He had dragged along his amoeba to wet-nurse by the sea- 

 shore, having diagnosed it in Cincinnati as one of the Limax 

 group, more determinately vahlkampfia, species No 1. This 

 meant that it never grew tails. He was just trying to discover
