nitrogen-containing proteins. A ration 

 wholly vegetable is almost certain to con- 

 tain a too low percentage of nitrogen, 

 while a ration exclusively animal is very 

 sure to be deficient in carbohydrates. As 

 a result of improper food, digestive dis- 

 orders soon appear, either in the liver and 

 gall-bladder, or in the intestines. Of the 

 chicks examined, 75.7 per cent had abnor- 

 mal livers; 38.6 per cent had various forms 

 of intestinal disorders." 



"In conclusion, special attention is called to the 

 following facts, confirmed by experiments:* 



"1. Careful external and internal examination 

 (such as any one can readily make) of the dead 

 chick will usually disclose the cause of death. The 

 necessary remedies are usually not difficult to find. 

 "2. Death from overcrowding, suffocation and 

 trampling can be readily corrected. It is more 

 frequent than is generally suspected. 



"3. For guarding against tuberculosis, give the 

 interior of the brooders all the sun and air pos- 

 sible on pleasant days. 



"4. Trouble of the liver and gall-bladder are 

 usually easily recognizable from the green stains. 

 For correcting this, feed more animal food. The 

 use of the proper proportion of animal food will 

 pay a handsome profit through decreased mortality
