Directions for Collecting 



[Jan. 



Animals, of whatever class, which are small enough to be preserved 

 whole, should be kept in that slate. 



Those which are too large to be transmitted entire in spirit, should' 

 be divided into such parts as characterize them. When this division 

 into parts is requisite, it will be necessary previously to take notice of 

 all the external appearances, the number of nipples in the female, and 

 their situation, whether between the anterior extremities, as in the 

 Monkey tribe, Bats, Elephant, Dugong, &c. ; or all along the belly, as 

 in the Sow, Bitch, Rat, &c. ; or between the hind legs, as in the Mare, 

 Cow, &c. If the female cannot be procured, then examine the nipples 

 of the male ; and indeed it is proper to examine every male, for it some- 

 times happens that these parts are concealed, as in the Horse. It is 

 hardly necessary to describe the external parts of the female, as, gene- 

 rally, the whole of them may be preserved. 



The situation and external appearances of the penis in its natural 

 state must be observed, whether it extends along the abdomen, as in 

 the Dog; or point backwards, as in the Cat, Rat, Rabbit, &c. ; whether 

 covered by the common skin, as in the Bull, Deer, Bear; or by a 

 proper skin, and only attached to the belly at the upper side, as in a 

 Dog, Horse, &c. And any other external appearance which cannot be 

 preserved, or where the parts are too large to be kept whole, should be 

 particularly noticed and described. 



When the examination has proceeded thus far, the dissection is to 

 be begun, by opening the abdomen, &c, to see what internal parts are 

 worthy of preservation. 



When the animal is opened for this purpose, it will be proper to 

 take a general view of the viscera in their natural situation ; to ascer- 

 tain the number of lobes of the liver, whether there be a gall-bladder, 

 &c, the situation and form of the stomach, spleen, caecum, kidneys, &c», 

 also to make such observations upon them as may be thought neces- 

 sary ; after which the parts may be separated and severally distin- 

 guished by appropriate labels. 



Animals whose food is not exactly known should have the contents 

 of the stomach and intestines examined, to ascertain, if possible, what 

 food they had last taken : the kind of faeces contained in the colon and 

 rectum should also be noted. 



The stomach and alimentary canal of Fishes, and other marine ani- 

 mals merit particular examination, as frequently containing not only 

 animals and parts of animals which inhabit great depths, and other 

 situations equally beyond the reach of ordinary observation, but also 

 singularly formed intestinal worms.
