312 ORISMOLOGY. 
implies a tendency to the quality expressed by it. As, 
Cificrascetis, cinerascent, tending to cinereous, &c. 
Rule V. 
The preposition ob prefixed to a term reverses it. 
As, O&conical, 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-a?neons, it means that the aeneous 
tint prevails: but if, vice versa, it is termed ceneo-nigrons, 
the black 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 cruciato-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 hirsu to- 
cinereous, we mean that the hirsuties only of a body 
is cinereous. 
Rule VII. 
When the term ordinary (ordinarius) is added either 
to terms expressing impressed puncta, lines, spots, &c, 
it signifies that such puncta, lines, or spots are common
