skin provided with an extraordinary muscle for erecting the quills. The mus- 

 culus carnosus of the hedgehog serves to bring the head round into the breech 

 like a foot ball; and whereas in the porcupine the caecum was very large, in the 

 hedgehog there was none at all; the epididymis, in the porcupine, was separate 

 from the testis; in the hedgehog united to it; in the hedgehog was a large cry- 

 stalline filling almost the whole globe of the eye. 



The IQth are four monkeys. In general it is observed that this animal more 

 resembles a man in his outward shape than inward formation of the parts, which 

 in many things are like a dog ; the genital parts of the male like neither ; of the 

 female much like woman ; the anfractuosities of the brain like man's, but the 

 processus mammillares were hard and membranous, which they are not in man ; 

 the muscles very much resemble those of men. 



The 20th is the stag of Canada and the Sardinian hind. In the stag, the 

 length of the intestines is observable, being in all 96 feet ; and indeed, gene- 

 rally all grazing animals have long guts. In the hind, the four ventricles were 

 more distinguishable than in the stag ; the cornua uteri long and winding, as in 

 the chamois; in the trunks of the jugulars were found 16 valves, which were in 

 situation contrary to the circulation of the blood. In the carotides were ob- 

 served several transverse incisures. 



The 21st, ten pintadoes. Several parts are like the common hen; the pan- 

 creas wanting ; the bladders in the lower belly were raised by blowing into the 

 aspera arteria, whence they hint at the use of respiration. 



The 22d, three eagles. The intestines, after the usual manner of voracious 

 animals, were slender and short, as also the kidneys ; some had the caecum, others 

 none; the globe of the eye was large, and the cornea very prominent. In this 

 subject they first discovered that the spinal marrow in the middle of the back 

 ;was divided in two, with a ventricle like those in the brain .between ; this was 

 afterwards found common to all birds. ncHl -fiiisr/' ,'t«. 



The 23d, two Indian cocks, not our Turkey cocks. In one there were two 

 pancreases, with three choliducts, and two pancreatic ducts into the intestine, in 

 the other was but one pancreas and a single duct; the intestines were 12 feet 

 long, and the caecum 6 ; the aspera arteria made a fold in the craw-bone, after 

 a moat particular manner, 'jjjft ty '"» ? "'^ 



The 2'lth, six bastards; in which the craw was scarcely distinguishable from 

 the oesophagus, and furnished with a great number of glands most conspicuous 

 in this, but to be found in most birds ; a third caecum near the rectum or the 

 ursa Fabritii, between the cornea and sclerotica, a cartilaginous circle was ob- 

 served. 

 The 25th, six damoiselles of Numidia, a kind of Crane, in which they found
