ation. Fig. 203 shows the organs removed from the abdominal 

 cavity of hen. They consist of (A) egg cluster, (B-B) egg pas- 

 sage, (G) cloaca, (D) frimbriated extremity of fallopian tubes. 

 The egg cluster lies in close proximity to the vertebral column, 

 slightly posterior to the lungs. From it the fallopian tubes and 

 egg passage proceed backward— in close relation to the vertebral 

 column, aorta and vena cava — to its outlet — cloaca. In the pullet 

 the egg cluster and egg passage are small. (See Fig. 204.) 



Fig. 204 — Intestines Removed in Order to Show Position of Egg Cluster and Egg Passage. 



G, Egg Cluster; H, Egg Passage. 



In a pullet of proper age for operation the egg passage is no 

 larger than an average size broom straw. The egg cluster in such 

 a pullet is small and flat, and shows no evidence of egg formation. 

 Beginners are urgently advised to kill and carefully examine these 

 parts in a full grown hen, also a three-months-old pullet before 

 operating. 



Warning — In removing section from egg passage caution 

 should be exercised not to sever either the aorta or vena cava. 

 Both are large and important blood vessels, and should either of 

 them be severed death from internal hemorrhage is almost instan- 

 taneous. It is important to have extra good light in order that the 

 abdominal cavity be illuminated sufficiently to locate the parts. 

 Bright sunshine is the ideal light for this operation. Out-of-doors 

 is the place, and from 10 a. m. to 2 p. m. is the time.
