DIGESTIVE ORGANS. 549 



the organs clean, lay them out, arranged in their natural posi- 

 tion. AV'hen perfectly dry, wash them with oil of turpentine, 

 and afterwards give them two coats of copal varnish. 



Or the digestive organs may be taken out, carefully dissected 

 and put into water for a night, or longer, to remove the blood. 

 Tie the rectum, and inflate them with a blowpipe introduced 

 into the oesophagus. Hang them up, or lay them out, to dry, 

 supporting the parts in their natural position by propping them 

 up with wool, or hair, or some other contrivance. When dry, 

 varnish, and suspend in a glass jar, of which the top is to be 

 secured with a bladder. 



Or these organs, as well as any others, may be preserved, after 

 being carefully dissected and well cleaned, in clear whisky of 

 ordinary strength, being suspended in a jar, which is secured 

 by a layer of bladder, a layer of tin or sheet lead, and an outer 

 layer of bladder, tied down, until dry, when the top is to be 

 painted and varnished. 



I have made some beautiful preparations in all these ways. 

 Among the best that I have is the entire intestinal canal of a 

 Sea-Eagle, and a Gannet, inflated and dried. A fine prepara- 

 tion of the entire intestinal canal of a Golden Eagle, filled with 

 white wax, I gave to Professor Jameson. To the use of all my 

 preparations any one is welcome ; and him who may excel ma 

 in making them, or in observing and describing birds, I will try 

 to admire, without envying ; although, to tell the plain truth, 

 I should really like to be first in these matters. 



Let every one have his turn. Mine comes next. But I hear 

 the steam whizzing. Let us be off". We shall have a rough 

 ride over the Frith. 



Good pupil, be not so dejected ; arouse thee ; let us look on 

 deck, and see the waves wash over it. AVhat a lovely sight ! 



Come, come, this is too serious I tell you. I never was be- 

 fore in such a sea. Yet those billows are awfully beautiful, and 

 the thick snow drives so furiously that I am sure the pilot can- 

 not see five yards ahead. I hope we shall not come foul of 

 the guard-ship. Let us down again to our den, and be thank- 

 ful that we are not in an open boat, or, like Arion, astride on 

 that porpoise.
