principles like these finds himself not seldom disheartened in the 

 prosecution of his studies under difficulties such as I have set forth. 

 If, however, as I have endeavoured to point out, these difficulties 

 can be overcome to a very considerable extent, is anything more 

 natural but that he should be the herald of his discoveries himself ? 

 Could anything be more unkind and ungenerous on the part of his 

 scientific 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 a 

 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 sound 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.
