The percentage of water is in these grasses, on the average, 

 higher than in the natural grasses ; but, in spite of this circum- 

 stance, the column appropriated to albuminous matters exhibits 

 numbers which exceed very considerably those in the previous 

 Table. In other words, weight for weight, even when fresh cut, 

 the " artificial " grasses contain a much larger proportion of 

 flesh-forming principles. How much this difference is increased 

 when the samples are compared in the state of hay will be seen 

 when we give, as we shall now do, the numbers which represent 

 the composition of the various grasses when dry. 



The Tables which follow (Nos. V. and VI.) give the composi- 

 tion of the whole series after drying at 212^ of Fahrenheit, until 

 all the moisture of the grass is expelled. 



There are many points of great interest brought out by these 

 Tables, and I might perhaps be pardoned for employing the 

 numbers they contain as tending to confirm or refute some of 

 the most important doctrines extant on the subject, both of vege- 

 table and animal nutrition. This, however, is not my object : 1 

 look upon these analyses as an addition to our previous know- 

 ledge — a contribution, in fact, to the data upon which all philo- 

 sophical reasoning should be built ; but whilst I should of course
