A NEW ACROLOPHUS FROM BRITISH GUIANA 117 



( 1 0) Philosophy of the facts thereby gained. 



The field is wide enough for all who may wish to come, and no one 

 need harbor petty jealousy of another's work. Facts and their philosophic 

 cispects must be recorded as the work progresses. If undigested, they 

 may be digested at leisure. Everyone's work will ultimately stand on its 

 exact merits. It requires time to pass correct judgment as to real merit. 

 Judgment must be unprejudiced. Work must bear the test of time. It 

 is both unwise and unseemly for a beginner in a difficult subject to ridi- 

 cule good work done by his predecessors. Caustic comment has no 

 legitimate place in taxonomic literature, and solves no problems. In the 

 minds of all right-thinking persons such comment serves no other purpose 

 than to reflect on the commentator. I bespeak a spirit of cordial coope- 

 ration on the part of my confreres. Such spirit will be both highly appre- 

 ciated and warmly reciprocated.
