The droppings were again examined with no discovery of nematodes or cestodes. 

 Gave to (M) some centrifuged heather washings containing a large number 

 of active and quiescent larval nematodes. 



Gave to (P) some concentrated culture of larval Trichostrongylus pergracilis, 

 taken from the dejecta of an infected Grouse, and recently prepared, not more 

 than three days before, from very active worms. 



Gave nothing to (S), which was to be kept as a control.

 dejecta clearly showed. 



Oct. 13. Examined caecal excreta with no result.

The following weights were taken with the hope that some loss would 

 show itself as the infection became established. 



But no infection took place. Nevertheless, as a series of daily weights 

 showing daily variations, due presumably to food, they are not altogether 

 without interest, and are therefore given.
