(4) TABLE SHOWING THE CHANGE IN WEIGHT OF GROUSE ARTIFICIALLY INFECTED 

 WITH STRONGYLOSIS AND COCCIDIOSIS. 



A. Stronyylotit case, died seventeen days after first infection, having lost 5 ounces of weight. 



B. Strongylosis case, died eighty-three days after first infection, having lost 5* ounces of weight. 



C. Strom/ylosis. Still living on May 17th, 1910, but with a significant loss of weight. 



E. Chick, died of Coccidiosis fifty-eight days after first infection with coccidia. Loss of weight not apparent 



as the bird was a young, growing ciiick. 



G. Coccidiosis case in a chick, which was apparently resistant to some extent to infection. Growing bird. 

 H. Stronyylosis case, in a young growing bird still living May 1910. Not badly infected. 

 I. Strongylosis case, in a young growing Grouse still living May 1910. Not badly infected. 

 /. Stronyylosis case, in a young growing Grouse still living in April 1910. See note on p. 112. 



NOTE. 



The inference to be drawn from these figures is that a marked sign of 

 Strongylosis is loss of weight, and even in the case of Grouse ( C), which 

 appears to be very resistant to infection (though treated almost exactly 

 in the same way as Grouse (B), the bird that died with very typical 

 Strongylosis), there was in May 1910 a very significant loss of weight 

 at the season of the year when it invariably shows itself in the wild
