In the preceding part of the prefent article we have 

 ilated, that this arrangement of the ftrata may be taken as an 

 approximation to the truth with certain limitations. It 

 muft be obferved alfo, that the trap rocks, N^ 9, moft fre- 

 quently occur covering or between many of the lower fecon- 

 dary rocks, precifely limilar to what would have been the 

 cafe had they been formed like volcanic rocks at different and 

 diftant epochs. The occurrence of bafalt in or over chalk, or 

 any of the formations above the has, is extremely rare. See 

 Systems of Geology.

GEZANGABEEN, or Perjmn Manna. This fubftance 

 has been lately aflerted by Capt. E. Frederick, of the Bom- 

 bay Eftablifliment, to be the production of infefts. It is 

 obtained, according to the fame gentleman, from a fmall 

 flirub fomewhat refembling the broom, on which the infefts 

 refide, by beating the buflies with a ilick. When firft fepa- 

 rated, it is a white fticky fubftance, not unlike hoar froft, 

 of a very rich fweet tafte. It is purified by boihng, and 

 then mixed up with rofe-water, flour, and piftachio-nuts 

 into cakes, and in this form conilitutes the fweetmeat, called 

 in Perfia gezangabeen, and which by the Perfians is highly 

 valued. This fubftance, in its original ftate, is faid to 

 liquify at a temperature of about 68°. The Perfians, how- 

 ever, themfelves confider this fubftance as a fpontaneous exu» 

 dation from the tree on which it is found ; hence the term 

 gezangabeen, a term meaning literally _/«/Vc of the gez, which 

 is the Perfian name of the tree producing it. Thorafon's 

 Annals of Philofophy, vol. xiii. See Manna.
