standing; and the ground from which these forms of under- 

 standing originate may be termed, collectively, the principles of 

 animal understanding, because they imply at the same time the 

 faculty of demonstration and the power of comprehension. 



Hence, this term implies logically the analyzation of the con- 

 stitutional ground of these principles, and therefore, will this be 

 the tendency and scope of this work, while the forms and modes 

 of gestures and sound-producing will be treated negatively, to a 

 certain extent, in so far as it is necessary to perfect the elucida- 

 tion of the subject. This is, for certain reasons firstly, it would 

 be too exhaustive, and secondly, the forms and modes of gestures 

 arid sound-producing are too familiar to most every one, that they 

 need an extra illustration in this work. Therefore, I have to state 

 here in advance to the kind reader that the plan of this work is 

 mostly based on the psychological ground and treated on from the 

 view of the transcendental standpoint.
