Chapters in. and iv. Note 10, pp. 535-538, records the degree 

 of buoyancy of the seeds and seed vessels of more than 300 

 British plants, including a large number of aquatics. The book 

 also contains numerous other notes on water plants, e.g. dis- 

 tribution of Naias, p. 367.)

 between the osmotic pressure in leaf and root in certain water 

 plants. For a criticism of his interpretation of his results see
