LIMA HIANS AND ITS MODE OF LIFE. 225 
connection with this curious animal, Its solution would perhaps 
throw light upon other obscure matters we have met with. 
Perhaps, for instance, it may be the scavenger of the household, 
whose sanitary arrangements we had cause to find fault with. 
It will be apparent that, in trying to understand the habits and 
mode of life of Lima, we have but raised a few questions which 
we cannot fully answer, and that many more such questions 
remain to be raised. In view of modern attainments in histo- 
logical work, of new ideas as to the relation between organism 
and environment, new conceptions of philogeny and embryology, 
this line of research is one that deserves increasing attention, and 
though it may be admitted to be difficult work, it is certainly the 
key to the solution of many scientific questions of the present 
day. It is a return to older methods of observation, but with 
increased means at our disposal for appreciating the significance 
of our observations.
