tent. The profile is not, however, that of the negro, although 
it has something of that race, especially in the lower part of the 
face. The nose, without being precisely flat, is still somewhat 
en cornet. The mouth is large, and very wide ; the lips have 
not, perhaps, been thick, but the mouth is considerably pro- 
truded, on account of the inclination of the teeth, which are ad- 
vanced, the lower meeting the upper. The incisors are much 
worn, and cut square, which is also the case with the canine ; 
the chin, however, does not retire. The ears seemed in general 
placed pretty high, and to have the lobule small. 
39. Silk Worm . — -In a communication to the Society for 
Arts and Manufactures, (vol. iv. p. 163.), it is stated by Miss 
Henrietta Rhodes, that one line of the silk-worm, when un- 
wound, measured 404 yards, and, when dry, weighed 3 grains. 
Hence it follows, that one pound avoirdupois of the thread, as 
spun by the worm, may be extended into a line 535 miles long, 
and that a thread which would encompass the earth would weigh 
no more than 47 pounds. 
40. Supposed Written Characters on the Wing of the Locust. 
— So many travellers, naturalists, and, it may be said, anti- 
quaries, have contributed to illustrate the subject of locusts, 
that I can add but little to the result of their researches. It 
must however be here remarked, that Zakaria Cazvini divides the 
locusts into two classes like horsemen and footmen, 6C mounted 
and pedestrians,” which will call to the recollection of the bibli- 
cal reader, some passages from Joel and the Apocalypse. 
That certain extraordinary words were supposed to be inscri- 
bed on the wings of locusts, different authors have related. The 
Sieur de Beauplan heard from persons well skilled in various 
languages, that the characters were Chaldaic, and formed Boze 
Guioiij words signifying the u Scourge of God.” But a much 
longer legend is exhibited on the wings of locusts, and in the 
Arabic language, if we may believe those mussulman writers, to 
whom I have referred in a former work. “ We are the army 
of the Mighty God ; we have each ninety and nine eggs ; and 
had we but the hundredth, we should consume the world, and 
all that it contains.” Whatever characters they may resemble, 
the marks appearing on locusts' wings are presented to the read-
