tetradactyla, llHg., which had recently been added to the Society's 

 Collection. Both individuals were extremely gentle, and suffered 

 themselves to be handled and played with, without evincing any 

 uneasiness. 



At the request of the Chairman, Mr. Martin reported the morbid 

 appearances observed in the Lio7i which recently died at the So- 

 ciety's Gardens. Before removing the skin, the whole of the body 

 presented a remarkably bloated appearance,which was found on exa- 

 mination to be owing to general emphysema. This was suspected by 

 Mr.Martin to be the result of morbid arterial secretion ; it could not 

 have been caused by putrefaction, the animal having been dead but 

 a few hours, and (he body being still warm. The same appearance 

 had been not unfrequently observed by Mr, Spooner, the Veteri- 

 nary Surgeon of the establishment, in animals worn out by linger- 

 ing chronic disease. On examining the lungs, their cellular struc- 

 ture was found completely obliterated, except in one small portion, 

 where alone any oxygenation of the blood could have taken place. 

 They presented a dark appearance on the surface, with a hardness 

 or density of structure which must have resulted from lon;;-conti- 

 nued inflammation. They were also partially studded with tubercles. 

 On cutting into them, purulent matter oozed from the incision, and 

 several abscesses, though not large, were discovered. The liver 

 was dark, and so soft as to break down with the slightest touch. 

 The spleen presented no decided trace of disease. The intestines 

 adjacent to the liver were tinged with a dark and somewhat purplish 

 hue ; but although distended with air presented nothing remark- 

 able. The stomach contained only a little bile and miicits. 



The muscles generally were pale and flabby, as might have been 

 nnticipctied, where a chronic disease had wasted the vital energies, 

 and where the blood, impeded in its passage through the lungs, had 

 long ceased to be sufficiently oxygenated. 



Mr. Owen commenced the reading of his account of the Myology 

 of the Simla Satijrus, L. He confined himself to the notice of 

 such muscles as are peculiar to that animal, and have not any ana- 

 logues in the human frame ; of those which, if analogous, deviate 

 remarkably in their proportions and attachments ; and lastly, of 

 such as have been considered as of doubtful existence in the Orang. 



The occipito-Ji-ontalis, which escaped the observation of Tyson 

 and Dr. Traill (Wernerian Trans, iii.) in the Chimpanzee , and which 

 some physiologists have asserted to be peculiar to man, is distinctly 

 developed in the Orang XJtan. Portions of this muscle were also 

 found on the head of a Chimpanzee that had been flayed with great 

 care, the rest having been removed with the scalp, to which the 

 tendinous part closely adheres. 



The following muscles of the face were described, corrugaior 

 supercilii, levator labii superioris alceqne nasi, levator angidi oris, 

 xj/gomaticus major, depressor anguli oris, orhctdaris palpebrarum 

 and orbicularis oris. On reflecting the inner membrane ot the lips.
