middle two the largest, the last the least: their 
base* is a triangle of the scalenus kind; or 
having one angle obtuse, and two acute. Their 
base is composed of two surfaces, an inner and 
an outer, divided by processes or points : it is 
the inner, that the grinders of the lower jaw 
oppose, when the mouth is regularly shut. 
The lower jaw has three fore teeth, or incisors, 
on each side : the first considerably the largest, 
projecting obliquely forwards; the other two 
of the same kind, but smaller ; the last the 
smallest. 
44 The holder in this jaw is not so large as 
in the upper jaw, and close to the incisors. 
There are three cuspidati ; the middle one the 
largest, the last the least: these are cones, 
standing on their base ; but not on the middle, 
rather on the exterior side. There are four 
grinders ; the two middle ones the largest, and 
rather quadrangular ; each of which has a 
ihigh point, or cone, on the outer edge; with a

/inner edge.
