 and defiance. 



The above account will give some idea of the vast numbers 

 and varieties of the termites and ants of this region, and of 

 the wonderful way in which Providence has furnished them 

 with the means of sustaining existence, and taking their part 

 in the economy of nature. Science is deeply indebted to 

 Mr. Bates, for his persevering efforts and acute observation 

 in making known the varieties and habits of these curious 

 insects.

Although the rest of the animal creation is small compared 

 with the creatures of the Eastern world, insects and reptiles
