II.— Lysimeter Water. 



Lysimeter water is catmospheric water pa-^sed by means of 

 suitable apparatus (Lysimeter) through different soils, and col- 

 lected after passing; through. (See page 92.) 



The chemical analyses embraced four series, and were made 

 by Dr. Zoeller. 



1. — Series of analyses made in 1857. 



The experiments were made with five different soils, 1 square 

 foot of each earth, 6 inches deep, being placed in the several 

 lysimeters. The quantities given represent the amount of 

 atmospheric water that passed through the several lysimeters 

 from April 7 to October 7, 1857. I. Manured calcareous soil, 

 with vegetation (barley). II. Unmanured clay soil, with vege- 

 tation. III. Unmanured clay soil, without vegetation. IV. 

 Manured clay soil, without vegetation. V. Maniu-ed clay soil, 

 with vegetation. (2 lbs. cattle-dung, without straw, were seve- 

 rally used to manure the earth in lysimeters I., IV., and V.)
