ger muscular fasciculus, arising from the anterior part of 
the base of the epiglottis (or, anterior and superior, sup- 
posing the epiglottis to be laid down upon the glottis), 
and running parallel with the preceding, to be fixed into 
the base of the arytenoid cartilages. These cords cor- 
respond with the superior or anterior vocal ligaments of 
the Mammalia, and there even appeared to be a small ca- 
vity or ventricle situated between them and the true vocal 
cord. 
The anatomy of the stomach, intestines, and liver, was 
found to coincide with the details in the Anatomic Com- 
paree The following table will give an idea of the pro- 
portional length of the intestinal canal in the Ornithoryn- 
chus, Echidna, and Fourmilier.

It is evident, I think, that the viscus called coecum, in 
the Ornithorynchus and Echidna, is merely an appendix 
vermiformis. A number of dark-coloured glands are situ- 
ated at the base of this appendix, and betwixt its tunics. 
• The spleen seemed to me to be bilobular, and measured nearly 4| 
inches in length ; it was regular as to situation.
