In order to preserve the specimens expanded they 

 should be removed and placed alive in a dish of sea- 

 Avater; and when they have protruded and expanded 

 their tentacles, the solution should be slowly and quietly 

 added to the sea-water, when the animal may be killed 

 and fixed in its expanded state. So prepared, the speci* 

 mens should be transferred to a bottle of iresh solution. 



In like manner the minute polypes of the flexible or 

 horny corals may be preserved protruded from their cells 



s 



and expanded. If a small piece of corrosive sublimate i 

 put into the vessel of sea-water containing such livina* 



polypes, it will kili or paralyse them when protruded, as 

 it slowly dissolves ; but they must be removed as soon as 

 they have lost their power of retraction, otherwise their 

 tissue is rendered fragile or is decomposed. The polypes 

 or animal part of the calcareous kinds, called " madre- 





pores," " millepores," " fungire," " red coral," 

 goniffi," &c., require for their preservation, ni connec- 

 tion with their supporting basis, the following solution
