44 Dr Craigie's Observatioiis on the 



blowing tube {fistula oujluste) attached to the windpipe, with 

 the larynx above fixed in the tube much in the same manner as 

 the reed of wind instruments {anches au cornemuse), and co- 

 vered by a valvular membrane which he names at once epiglot- 

 tis and luette, with two productions on each side. This account 

 is, on the whole, accurate ; and the slight mistakes are to be as- 

 cribed to the erroneous notions then entertained on the uses of 

 the parts. It shews that Belon was aware of the peculiar mode 

 of respiration in the cetaceous animals, and of their title to be 

 ranked with warm-blooded animals. 



This accuracy is not less apparent in his account of the heart, 

 which, he remarks, is contained within the pericardium, and has 

 two auricles and two ventricles, like that of man, to wh^h,,^, 

 deed, he represents it as altogether similar. .i;rroRV.f(7 



Though he appears to have examined carefully the alimentary 

 canal and abdominal viscera, both in the dolphin and porpoise, 

 and remarks the position of the stomach below the liver, he omits 

 its quadruple form ; and the only approach which he makes to this 

 fact, is when he informs us that its portion termed jt?7/Zor?/*, known 

 among the peasantry by the name of caillette, because it is used 

 for supplying rennet, is half a foot long, and contains as much 

 as the third part of the stomach. The Jejunum a.nd.ileum form 

 numerous turns or convolutions, as in the intestine of the calf. 

 The want ofc<:EC?/m he accurately observes ; and that the intestine 

 for receiving the excrement, or colon and rectum, is more slen- 

 der than the rest of the canal, in opposition to what is observed 

 in other animals. The connexion of the canal with the spine by 

 means of the mesentery, as well as the site of the mesenteric 

 vessels, he also observes ; and though, like the anatomists of tha,t 

 time, he does not distinguish the veins from the arteries, hefio^r 

 rectly remarks the termination of the mesenteric veins in the 

 portal trunk, which, he observes, is distinct, and sufficiently ca- 

 pacious to admit the finger. He distinguishes the situation of 

 the vejia azygos on the right side of the spine and its tribu- 

 taries ; and though he marks accurately the situation of the 

 vena cava, he erroneously, like the ancient anatomists, represents 

 it to arise from the liver. Lastly, it is a remarkable proof of 

 the accuracy of his observation, that, while he mentions the si- 

 tuation of the spleen and the liver, and remarks that the latter 

 is in one mass in the dolphin and porpoise, as in man, and that
