denum, that for the first loose part, and that for the last loose part of 

 the intestines. The lacteals pass along with the vessels of the three 

 mesenteries towards the hack : those of the last or lower mesentery 

 communicate ahove with the others : at the root of the mesentery and 

 near to the termination of the abdomen they pass to the back between 

 the two kidneys, and j; hi [the thoracic duct] at the side of the aorta. 



The oviduct was very large, and so were the ova. They were 

 attached to the great vessels of the back by a ligament nearly half a 

 foot long, and 2 inches broad, through which the vessels passed to the 

 ova. The eggs were attached to the edges of this ligament, which 

 attachment was by long strings, so that they were twisted one with 

 another 1 . 



The air-cells communicate with the joint of the thigh and knee, 

 by the ham along the great vessels beside the ramifications of 

 the vessels in the thigh ; there the air-cells pass along with them. 

 There are two durae matres to the medulla spinalis ; one is pretty 

 loose, the other lies close to the medulla ; underneath which is the pia 

 mater. The medulla is almost two [chords] lying close to one another, 

 but united at one edge 2 . 



The ischiadic nerve in the thigh is still pulpy ; for at the cut ends, 

 when steeped in water, it was found to be squeezed out by the swelling 

 of the nerve within its coat. This coat is strong, and makes one sheath 

 for it, so that it can be dissected off. 



The jugular vein of the ostrich has in some places three valves ; in 

 other places only two : and there is but one principal [vein], which is 

 on the right side. 



The vessels of the thigh-bone pass in at the passage for the air. 



The joint of the ankle of the ostrich does not move upon the centre ; 

 the middle part of the joint from side to side being the most projecting, 

 so that it is easiest when either in flexion or extension. 



[Order Grallatores.] 

 The Bustard [Otis tarda, Linn.]. 



The cock-bustard has a very thick neck and long hairy feathers 

 under his throat. On the fore part of his neck, reaching lower down 

 than the middle, is a large bag as large as the thick part of one's arm : 

 it terminates in a blind pouch below, but has an opening into it at the 

 upper end from the mouth. This aperture will admit three or four 

 fingers ; it is under the tongue, and the frsenum linguae seems to enter
