This paper cannot be of much use to this productive Meeting but 

 I put it forward with the idea of eliciting information. 



I am rather doubtful myself as regards the present necessity for 

 the introduction of such a scheme. One difficulty is the fact that a 

 publication may fall under several distinct heads at the same time. 

 Another difficulty, so far at least as concerns the main subjects of the 

 classification of literature on Forest Zoology as given by Mr. Beeson, 

 is that this classification does not go far enough. Neuroptera for example 

 includes very diverse groups which are usually regarded nowadays as 

 Orders and will undoubtedly be given ordiiial rank by general consent 

 in the near future. This system therefore presupposes the permanency 

 of our classification, which is far from being the case. 



I do not suggest this for general adoption. A modification of the 

 system is essential. You must have cross-references, letter-files, and so 

 on, to complete it. 



I keep a card index also and started it by Families and put all the 

 information for a particular sj^ecies under that species. I number
