time. The contents of the cyst in most Protozoa break up into 

 several individuals, which eventually issue forth from a rupture in the 

 envelope. In this way the species is preserved from one season to 

 another. The cysts are very small and light, so that when dry they are 

 taken up by any breath of wind and so diffused far and wide. At all 

 seasons there must be millions of these organisms floating in the air 

 and settling everywhere, ready to come into being whenever and wher- 

 ever the conditions are favourable. 



The name " Infusoria" was applied originally to the minute beings 

 which were found swarming in infusions of hay, &c. It was thought 

 that the decayed organic matter actually generated these tiny creatures, 

 but the real source of their presence was the air acting as a carrier. It 

 is known now that the air conveys not only Infusoria and Rotifers, but 

 spores of mosses, ferns, fungi, algae, and the microbes or germs of many 

 of the diseases which attack man and animals. 



We have dealt at length with the structure and physiology of Amceba 

 as a typical Protozoan, and this course was adopted in order to gain a 

 clear idea of the general principles which govern a simple organism in 

 its three aspects of Relation, Nutrition, and Reproduction. In our 

 next chapter we intend taking a few other Protozoic forms in an ascend- 

 ing scale, and showing how the simple Amceba type is modified in each 

 case, whilst the essential elements of the cell remain the same.

 London: two collectors one day took ninety chrysalids each and left many more. — C. M.
