alternately ; and the loudness of the sound is aug- 

 mented by a deep cavity on each side of the body, 

 in which there is a drum, or little membrane, in a

 sists of strong nerv'ures or rough strings in the wing- 

 cases, by the friction of which against each other a 

 sound is produced, and communicated to the mem- 

 branes stretched between them. The males only

 enumerate the various passages scattered throughout 

 the Holy Scriptures, in which grasshoppers are men- 

 tioned. I shall only remind you of the fact, that 

 these insects, along with locusts and beetles, are 

 among the animals allowed to be eaten under the 

 Mosaical dispensation. The words in which the 

 permission is conveyed are striking to the Entomo- 

 logist, as showing that three species of insects belong- 

 ing to the order (Orthoptera) now under consider- 

 ation, were recognized as distinct. The words occur 

 in Leviticus (chap. xi. ver. 20 — 23.) 



" 20. All fowls that creep, going upon all four, shall be an abomi- 

 nation unto you.
