were infected with hookworm.' They were given on 

 November 1, 3 cc. of carbon tetrachloride by stomach tube, 

 which was followed by 1 ounce of magnesium sulfate in 

 water. 



In view of subsequent developments there is no reason to 

 suppose that the hookworms importantly influenced Panzee 's 

 condition. All of her symptoms indicated digestive disorder. 

 Her appetite was poor, extremely variable, and the condition 

 of her bowels bad, tending toward diarrhea. Much of the 

 time she preferred to lie in her nest and it was seldom possible 

 to experiment with her. Because of the nature of the 

 symptoms and the writer 's inexperience tuberculosis was not 

 suspected until too late. Meantime all resources were 

 exhausted in efforts to discover the nature of the digestive 

 disorder. 



1 1 am indebted to Drs. G. W. McCoy and C. W. Stiles of the Hygienic 

 Laboratory for examination and advice, and to Drs. Morris C. Hall and 

 Jacob E. Shillinger of the Bureau of Animal Industry, for treatment of 

 the animals and valuable advice.
