The outer iou is composed of the longest plates; 

 and these are in proportion to the different dis- 

 fences between the two jaws, some being four- 

 teen or fifteen feet long, and twelve or fifteen 

 inches broad; but towards the anterior and pos- 

 i part of the mouth they are very short: they 

 rise for half a root or more, nearly of equal 

 JnniHtiif. and afterwards shelve off from their 

 inner side until they come near to a point at tin- 

 outer: the cxtutor of the inner rows ace the 

 longest, corresponding at the termination of the 

 declivity of the outer, and become shorter and 

 -ImrUT till they hardly ri<e abovye the gum. The 

 inner rows are closer than the outer, and rise al- 

 most perpendicularly from the gum, being longi- 

 tudinally strait, and have less of the declivity 

 than the outer. The plates of the outer row la- 

 terally are not quite Hat, but make a serpentine 

 line. ially in the Piked Whale: the outer 



edge is thicker than tiic inner. All round the line 

 made by their outer rc-rs, runs a small white 

 nieli JN louned along with the whalebone, 

 and \\car> down with it. The smaller plates are 

 iv of an equal thickness upon both edges. 

 In all of them Hie termination is in a kind of hair, 

 as if the plate was .split into innumerable small 

 pair-. ii. ' xt< rior being the longest and strongest.
