 grasses. Their extension cannot be accurately ascer- 

 tained : it appears, however, from different obsenra- 



towards the poles, they extend beyond thai region 

 where the sow-fine reaches the level of the sea, hut 

 that they grow principally in the seas of wanner cli-

 creasing towards the Equator. 



2. Daring the summer, a green weed grows in fresh 

 water, which gradually IIIIM into xlank 

 threads (eon/erar), or extends to stdnn 



or star-jellies (tremuOe). As such substances shew 

 the continual growth of plants out of the fluid ele- 

 nent, and as they occur in ponds and ditches in great 

 quantities during the latter part of the autumn and the 

 spring, their extension on the main land is designed 

 from the snow-line to the Torrid Zone; but their 

 native country is the vicinity of the limit of perpetual

 coincides with that of the COJI/CTT* and trcmeU* : 

 they grow partly on the leaves and fruits of plants,
