sisted in part of good grasses, with admixture of carices, juncacejie, and 

 dicotyledonous swamp-grasses, especially CaWiajjahistris. Unfortuately, 

 late mowing prevented as extensive investigations in this as in previous 

 cases. 



The matter collected in three tests contained, in the fresh and the air- 

 dried condition, the following constituents :

The low percentage of water in this sample was due partly to its being 

 too ripe, and partly to the fact that it had been mowed for some time. 



The plants collected from the natural meadow were Ranunculus Flani- 

 mula^ Senecio aquaticus, Spira'a ulmaria, Caltha palustris, Lychnis Jios cu- 

 culi, Lyshnachia numviularia, Galium palustre, JEquisetutn pahistre^ Juncus

The comparison of these tables with the preceding, by means of the 

 ratios given in the lower portion, is easily made. A fact which seems 

 worthy of notice is that in all of the six analyses the figures represent- 

 ing the entire nourishment in the ratios are included within the limits 

 1.8 and 2.4, and these limits will be observed in the following analyses. 



The following tables are the results of analyses of materials collected 

 from a meadow, cultivated according to the Peterson method, and an 

 adjoining one in the natural condition, near Cappeln. In the first lot, 

 collected the following plants — 



Arrbenatherum elatins 105 centimeters high. 



Lolium perenne 90 centimeters high. 



Phleum prateuse 84 centimeters high. 



Holcus luuatus 102 centimeters high. 



Tripolium hybridum —
