312 ORISMOLOGY. 



implies a tendency to the quality expressed by it. As, 

 CinerascenS) cinerascent, tending to cinereous, &c. 



RULE V. 



The preposition ob prefixed to a term reverses it. 

 As, Ofaonical, O&cordate, a conical or heart-shaped 

 body, of which the narrowest part is the base. 



RULE VI. 



In compound terms the last member indicates the 

 preponderating character. For instance, when it is said 

 of a body that it is nigro-ceneous, it means that the aeneous 

 tint prevails: but if, vice versa, it is termed <zneo-nigrous, 

 the Iplack tint is predominant. N.B. In Sculpture the 

 terms punctato-striate, or punctato-sulcate, signify that 

 striae or furrows are drawn with puncta in them. 



Exception 1. 



Some compound terms only indicate the union of two 

 characters in one subject. As, when we say of wings 

 that they are cruciate-incumbent, we mean both that 

 they cross each other and are incumbent upon the body. 



Exception 2. 



Compound terms are sometimes employed very con- 

 veniently to restrict the application of a character to 

 particular circumstances. As, when we say hirsuto- 

 cinereous, we mean that the hirsuties only of a body 

 is cinereous. 



RULE VII. 



When the term ordinary (or dinar ius) is added either 

 to terms expressing impressed puncta, lines, spots, &c., 

 it signifies that such puncta, lines, or spots are common
