died in the hospital, and found the form to be nearly as represented 

 in hgure 2 where d d, //indicate the antrum pylori. This part is also 

 distinguished by greater thickness of its muscular coat, more stronglv 

 developed glands, and the presence of the well-known plies fimbriate

 cavity, which I should propose to name the antrum duodeni, and 

 which is characterized interaaUy by the absence of valvule conni-

 mucous membrane. This part constitutes what has been called the 

 fourth stomach of the Porpoise, and some other Cetaceans. I may 

 observe that the so-called ligaments of the pylorus are connected 

 with the formation of the antrum pylori. 



" 3. On the Fascia Superficialis. 

 " The accounts usually given of the fascia superficialis are for the 

 most part very imperfect. As far as I can judge, this fascia is in 

 many parts of the body a constant membrane, and really appertains to 

 the skin, as may be particularly well seen in the integuments of the 

 back. The cutaneous muscle of quadrupeds, in most cases, probably 

 arises out of this fascia ; the muscular fibres being deposited, as I 

 conceive, in the midst of its substance, and finally becoming covered 

 by it as their perimysium. In this way too, I imagine the platysma 

 myoides and epicranius to be formed."
