52 PRELIMINARY COLD STORAGE STUDIES. 



had been preserved under the conditions previously noted for 119 

 days. An undrawn and a drawn specimen were examined simul- 

 taneously, and comparisons not only with a fresh fowl but with 

 one another were made. 



From the undrawn fowl only the feathers were removed. From 

 the drawn, the head, feet, legs, crop, and intestines were removed. 

 Originally the lungs, heart, liver, spleen, testicles, and kidneys were 

 left in position, and the gizzard was emptied and returned to the 

 body cavity. 



Externally both of these chickens showed some broken skin. Both 

 had an odor, but that of the undrawn fowl was faint and not unpleas- 

 ant, though rather different from that of the fresh bird, but distinctly 

 better than that of the drawn fowl, where indications of beginning 

 putrefaction were plainly evident — a condition observed for the 

 undrawn around the head only. That portion, however, was dis- 

 tinctly foul. In the undrawn chicken there was no apparent change 

 in the color, while in the drawn there was a tinge of greenish yellow 

 in fat and subcutaneous muscle. 



The viscera of the undrawn fowl were in very good condition, and 

 the fecal odor noticed when the incision was first made soon dis- 

 appeared. There was some bloody effusion present in the lymph 

 spaces of the abdominal cavity. Tins was always noted for the drawn 

 bird. The liver was pale in color, but of good texture. It was some- 

 what green where in contact with the gall-bladder ducts. The tes- 

 ticles and mesenteric fat were somewhat more yellow than in the 

 fresh chicken. This also applied to the chicken from which the viscera 

 had been removed. Cultures were made both from the organs and 

 from the muscles. 



The infected organs and also the list of species, and their sources, 

 in the chicken will be found in the accompanying table under speci- 

 mens Nos. 4251 and 4252, respectively. 



The second examination of cold-storage chickens was made when 

 storage had continued for 215 days. As in the former examination, 

 there was a comparison of the drawn and the undrawn cold-storage 

 chickens with one another and with a fresh chicken. The undrawn 

 chicken had a broken right leg, which was dry and dark in color. The 

 drawn chicken had a broken right wing, which was also dark and 

 bloody, with an odor of putrefaction. 



The undrawn chicken had a strongly fecal odor in the region of the 

 vent, which was less marked toward the anterior end of the body. 

 The head, however, had a strong odor. In the drawn chicken the 

 odor was mildly rancid, somewhat butyric in character, and but 

 slightly putrefactive. 



The tissues of the undrawn chicken were soft, watery, and rather 

 slimy, both to appearance and to touch. The same condition was
