organs are all very pale. The liver may have a few streaks 

 showing congested areas. Some of the unabsorbed yolk 

 may or may not be present. There is considerable ^'ariation 

 in its api)earance. It is not usually putrid unless the chick 

 has been dead for some time. 



The following post-mortem appearances in bacillary 

 white diarrhea are reported by Rettger and Stoneburn : ^ 



" Crops — Empty or partially filled with slimy fluid or 

 wuth food. 



" Lungs — Apparently normal. (Tubercles not ob- 

 served.) 



"Liver — Pale, with streaks and patches of red. These 

 apparently slightly congested areas are usually large in size. 



"Kidney and Spleen — Apparently normal. 



" Intestines — Pale, and for the greater part empty. A 

 small amount of dark grayish or brownish matter frequently 

 present. 



" Ceca — With few exceptions but partially filled with a 

 grayish soft material. Only occasionally cheesy or firm 

 contents. 



" Unabsorbed Yolk — Usually present varying in size 

 from a pea to a full-sized yolk. The color may vary from 

 yellow to brownish green or nearly black. In consistency 

 there is also much variation. It may appear perfectly 

 normal, distinctly gelatinous, or watery. Frequently it is 

 observed in the character of custard and again more or less 

 dry and firm. Unless the chick has been dead for some 

 time the yolk is usually not found putrid, but merely stale. 



"The chick as a whole appears more or less ansemic and 

 emaciated. The muscles of the wings, breast and legs may 

 be almost completely wasted away."
