But though these authors thus cautiously avoid enlisting 
selves into the ranks of system, yet we think it is ob- 
vious, that, so far as the origin of trap rocks is concerned, 
they (certainly Mr. Conybeare,) lean to Huttonian views. 
He presents us, ina note, with a succinct statement of 
the arguments for the hypothesis, that ascribes important 
tised observer will be struck with the marks of the former 
action of heat, which they present ; while the most acute 
examination serves only to bring more of these marks to 
light. The resemblance of the amygdaloidal traps to cer- 
tain varieties of lava ; the convulsion and distortion of other 
strata in their vicinity ; the change in other rocks in coD- 
ith trap dykes, answering precisely to the actio® 
of heat; and the fact, that the strata, through which these 
dykes pass, are often bent upwards, near the line of con- 
tact, to what, but a volcanic agency, can such circumstan- 
ces lead the mind? 
granite as wellas to trap rocks. Indeed, consistency seems 
to demand such a conclusion. For although the proofs of 
such an origin may not be so numerous in regard to gra0- 
ite as to trap, yet the most important ones are common (0 
both. Granite exists in the form of beds, veins, and irreg”
