The Peesident's Anniveesaet Addeess. 



Amongst living organisms, it is only those which are green from 

 the presence of chlorophyll, and a few Bacteria, that are capable of 

 forming the complex substances composing their bodies from 

 inorganic materials alone. All other creatures are directly or 

 indirectly dependent on these for some of their food-materials. 



Not alone are animals and plants thus largely dependent one 

 upon another for food, for the importance of insect and, to a certain 

 extent, of bird agency in conveying pollen for the fertilization 

 of the seed has long been recognized. Animals also play an 

 important part in the necessary dispersion of plants, the seeds 

 and fruits of which are often specially modified by possessing 

 hooks, barbs, &c., favouring their temporary entanglement 

 amongst hairs or feathers. Besides the above-mentioned re- 

 lationships between living things, we find many cases in which 

 there is a very constant and close association of different forms, 

 an association which we may, following Van Beneden, con- 

 veniently divide into three groups, viz. : — 1st, Messmates or 

 Commensals ; 2nd, Mutualists or Symbiotic forms ; 3rd, Parasites.
