rotifers taken from a subtropical forest in the extreme north of New Zealand, and 

 subjected to low temperatures at Cape Royds, revived on being moistened. Many 

 Rotifers, Bdelloids at least, do not require much, if any, extension of their powers of 

 endurance to fit them for life in the polar regions, so that if species are few in the 

 Antarctic it is almost certainly because of mechanical difficulties in the way of getting 

 there. 



Vitality of Rotifers. Observations on the Biology of the Rotifera constituted the 

 most interesting part of the naturalist's work in the Antarctic. Many experiments, 

 of a very simple nature, were made upon them in order to ascertain their powers of 

 resistance to every kind of adverse circumstance which might affect them in the 

 course of a migration to Antarctica, or from place to place in it. 



These observations and experiments will be described in detail in a paper now in 

 preparation. A short summary of the most interesting points will be found under 

 the descriptions of Philodina gregaria and Adineta grandis in the preceding pages.
