54 PRELIMINARY COLD STORAGE STUDIES. 



cavity of the undrawn chicken showed a pale, jaundiced liver; mot- 

 tled grayish-yellow lungs; darkened kidneys and degenerated intes- 

 tines. 



In the drawn chicken the lungs, heart, and kidneys remained in 

 situ. They were all of a muddy, dark red appearance and there 

 was a thin sanguineous fluid in the body cavity. In general, the 

 interior of this bird was more degenerated than that of the undraw T n, 

 though the odor of the undrawn, especially the abdominal cavity, 

 was distinctly fecal. 



The final examination to be reported at this time was made when 

 the chickens had been in storage 610 days. These chickens, as indi- 

 cated in the table, where they are designated Nos. B. C. 695 and 

 B. C. 696, show a more widespread, and also a more varied, bacterial 

 invasion, than the cold-stored chickens previously examined. Their 

 odor was rancid, the drawn having less odor than the undrawn. The 

 tissues were generally desiccated. The skin was watery in appear- 

 ance. The undrawn chicken was practically free from abrasions. 

 The drawn had over the surface of one thigh an area of torn skin. 

 Both chickens were discolored in the region of the vent. 



Internally the undrawn chicken showed greenish-yellow fat and 

 flabby heart; dark congested lungs, very watery; a pale yellow liver, 

 very soft; a gizzard which was soft, flabby, and degenerated; intes- 

 tines which were pale, grayish-yellow, watery, and somewhat shiny; 

 a dark spleen and dark kidneys; a reddened bone marrow; body walls 

 which in the region of the liver were deeply stained w T ith bile pig- 

 ment, and in the abdominal cavity itself a considerable quantity of 

 thin, watery, bloody fluid. 



In the drawn chicken the whole interior of the body cavity was 

 dark in color and very bloody ; heart and lungs dark and full of a thin, 

 watery blood. The kidneys had practically the same appearance, all 

 looking like pieces of old leather. This fowl, in general appearance, 

 was not as good as the undrawn. 



It is of interest to note that the species of organisms in the drawn 

 and the undrawn fowl examined simultaneously have a very strong 

 similarity and in many cases a coincidence. If, as is asserted by 

 some, the bacterial invasion of the fowl in cold storage is due to the 

 migration of the organisms from the intestinal canal into the tissues, 

 one would expect in a draw^n fowl, properly prepared, either a lack 

 of organisms or the presence of species different from those found in 

 the undrawn. It is quite possible, however, that the drawing of the 

 fowl may be done in such wise that the organisms of the intestine are 

 permitted to gain access to the viscera, in which case they would 

 undoubtedly be found in the tissues. Gas-producing organisms, 

 which have their ultimate habitat in the intestine, have, as will be 

 noticed in the list of species, been isolated in certain cases. How-
