360 NATURAL SCIENCE [May 



ters of neuratiou are not understood by the writer, in that the generalised form is made 

 on occasion to proceed from the specialised, instead of the reverse. 



But it cannot be my intention here, nor will it serve my purpose, to enter into a 

 detailed criticism of Mr Meyrick's writings. It is sufficient to show that Mr Meyrick's 

 arrangements are unsafe and should clearly not lie trusted to in a M'ork of the general 

 character proposed by the British Museum. This work should recognise the main 

 groups in the sequence adopted, not by Mr Meyrick, but by Linne and Fabricius, while 

 any changes in the composition of these groups should be limited to such for which a 

 large amount of evidence has been recorded. It is, philosophically speaking, certain 

 that a linear arrangement is in itself unnatural, but the practical difficulty of reflecting 

 the probable phylogeny in our books is not obviated by adopting Mr Meyrick's ' lines ' 

 in the present case. To trust to these will, it appears to me, endanger the undertaking 

 and set the whole work adrift at the outset, while their employment will prevent many, 

 through lack of confidence, from embarking and sharing in the labours of the voyage.
