(The author describes experiments showing that the gas given 

 off by aquatic plants exposed to light is a mixture of oxygen 

 and nitrogen: he holds that this nitrogen is produced by 

 decomposition of the substance of the plant.)

(The first account of the peculiar turions of this plant. 

 According to the author, they are unique among organs of 

 vegetative reproduction in their horny consistency, and also 

 in the fact that the detached shoot grows no further, but its 

 whole vitality is concentrated in its axillary buds.)

[A description of the anatomy and morphology of this species, 

 less detailed than that of Caspary, R. (1859 and 1862). 

 A brief account of early references to the plant is given in an 

 appendix.]

(The author makes out what appears to be a good case for 

 regarding Oenanthe fluviatilis as a species distinct from Oe. 

 Phellandrium, Lamk., instead of as a mere variety of it.)

(A comparison of the anatomy of stems of different individuals 

 of the same species, or of different parts of the same stem, 

 grown in water, in air, or embedded in soil beneath water 

 A very important contribution to the experimental anatomy 

 of water plants.)
