CHAPTER VI. 
OF THE SECOND KIND, OR DIVISION OF LEAPERS, OR 
PHALANGIA. 
I* I HAVE placed the Phalangia before the Cancriformes, becaufe they are more numerous 
and more regular. 
2. The only certain character of this divifion is the fituation of the eyes in a parabola. Thofe 
in front are the largeft j next come the fecond, fomewhat lefs ; the third pair is the fmalleft j 
and the hindmoft pair are rather lefs than the fecond. See the figures. 
3. There is no certain rule for the length; fee the lines in the figures, wherein the firil 
gives the length of the fore legs, and the laft that of the hind ones. 
4. These Spiders have the power of bending the thorax very much, and very eafily to 
either fide, which thofe of the other divifions cannot do. They leap frequently with great 
lightnefs, like fleas or grafshoppers. Mofl: of them draw a thread after them, and which they 
can fix either to themfelves or to any thing elfe, or lengthen or fhorten at pleafure with won- 
derful facility.
