respect) we may readily conceive the rapturous excitement 
manifested by the new comer from the lost domicile, as 
compared with the lassitude and despondency exhibited by 
the lorn home-seekers; nor can we err in assuming that, 
after the customary greetings of recognition on the deserted 
side, some conscious allurement must have been imparted to 
the latter to induce them to confide in such cogent invocation 
to follow the former; her object being attained as though her 
motives had been enunciated by voice or language, and her 
summons conveyed through such a medium. 
Fertilization of Flowers by Insects.—The fertilization of 
flowers by insects (treated in several additional papers in 
‘Nature’ by Messrs. Hermann Miiller and T. H. Farrer) has 
also been the subject of a very remarkable Address by Sir 
John Lubbock, before the British Association, at Belfast, 
showing their mutual dependence upon each other, and 
pointing out how the sustenance afforded to the latter is 
requited by the transfer of pollen essential to the existence 
of the former, while calling attention to many structural 
peculiarities exhibited on either side admirably adapted for 
this purpose. But in discussing the mouth-parts and legs 
among the bees and wasps, upon which considerable stress is 
laid, as exemplifying modifications of these parts from an 
ancestral type, it should not be lost sight of that such suitable 
adaptation of organs to the requirements of the several races 
alluded to, is associated with many characteristic distinctions 
in the veining of the wings, coinciding with other relations 
of lineage and affinity, and furnishing, together with the 
aforesaid organs, premonitory indications of differences in 
habits and economy. ‘‘ That the mouth of Prosopis” (one of 
the solitary bees) “ probably represents the condition of that 
of the ancestors of the hive-bees before their mouth-parts 
underwent special modifications;” and that this “may be 
inferred from the fact that the same type occurs in other 
allied groups, as shown in the mouth of a wasp” (our 
“ Polistes,” to wit), is a deduction scarcely reconcilable with 
those divergences in alary structure between the respective 
groups, which are altogether independent of functional 
development, and of those influences for adaptational 
purposes which have been held to determine the survival of 
the fittest.
