brethren at home, than to oppose and discourage him by their 

 disapprobation ? 



I might enlarge on this subject, which has been a sore one 

 with me for a long time, to a great extent, but I think this is 

 sufficient to direct the reader into the train of my ideas and to 

 enable him to follow it up. 



I hasten therefore to conclude. As mentioned above, the 

 Tropical entomologist has a proportionate share of advantages 

 to balance what falls to his lot of the contrary ; one of these 

 advantages which he has over his brethren at home is, that 

 he has an opportunity of seeing and studying alive what can 

 at home only be examined in state differing more or less 

 from that of life. Therefore, if he is enabled and expected to 

 describe new species, it is moreover highly desirable for the 

 sake of the promulgation of sown d information, that he should 

 do so, that he should avail himself of this, his principal 

 advantage, and describe, fresh from nature, as many of his 

 favourites and their habits as possible ; and discouraging him 

 in such an undertaking on any of the above grounds would be 

 discouraging the progress of science in general.
