(4), to be finally inserted, broad and fleshy, into the sternal end of 

 the first, second, and third ribs. Its total length is 9 inches. 



Arises from the lower third of the sternum ; and is inserted into the 

 middle of the second rib. 



The Kev. Samuel Haughton, M. D., Fellow of Trinity College, 

 Dublin, read the following paper : — 



No. X. — Muscular Anatomy of the Emu {Dromceus Novce 

 Hollandice). 



I am indebted to the kindness of Mr. Thomas Moore, Curator of the 

 Derby Museum, of Liverpool, for the opportunity of dissecting a fine 

 male specimen of the Emu {Dromceus Novce Hollandice). This bird was 

 sent to me from London (1865) ; and, having reached Dublin two days 

 after death, was quite fresh, and in fine condition for dissection. On 

 inspection it presented tubercles of the liver (Farre's?), an enormous 

 developement of omental fat, and fibrinous clots, partly melanotic, in 

 all its arteries. 



I had also, through Professor Huxley, applied to the Council of the 

 Zoological Society of London, for permission to dissect the muscles of 

 the Ostrich, Emu, or Cassowary, in case such birds should die in their 

 Gardens, and their bodies not be more favourably disposed of. In con- 

 sequence of this application I received, 27th of April, 1866, the second 

 Emu described in this note, which proved to be a larger and finer bird 

 than the first ; and I beg leave to take the present opportunity of re- 

 turning my thanks to Professor Huxley, to Dr. Sclater, and to Dr. 

 Murie, of the London Gardens, for the kindness with which they aided 

 me in my attempt to procure specimens of these rare birds for the pur- 

 poses of scientific research. 



The examination of the muscles of these two Emus afforded the fol- 

 lowing results : —
