gantic rpgions more thoroughly than has yet been attempted ; or there is 

 an ample field for research and speculation. We shall feel much indebt- 

 ed to him, if he will explain how the Copridas were transported from one 

 country to another, and how they reached the island of Ceylon ; how 

 also Cetonia cornuta, which is taken on the banks of the Gambia, be- 

 came an inhabitant of India. Lytta gigas may have travelled by land, 

 and perhaps the Copridae following the track and droppings of the camel, 

 may have pursued the same route. Let him describe the sands of the 

 desert and those in the vicinity of the Indus, give us a comparative Fauna 

 of the Ganges and the Nile, record the varieties of temperature, the 

 character of vegetation, and the genera peculiar to the dilferent 

 soils. Let him do this, following the steps of the celebrated Forskal, and 

 he indeed will advance the objects of science, deserve the thanks of thQ 

 present generation, and command the respect of posterity.*

* By pursuing the course recommended by Ml'. Hope, anaturalist would be enabled, not 

 only to display the connection between soil, temperature, and vegetation, as well as the 

 animal forms which the latter supports, but also prove the advautasjes of studying^ the 

 natural sciences in connection with each other, and be enabled to explain something of 

 the laws which influence the geographical distribution of plants and animals,— J. F. R.
