 chlorine, 2.2 kil. of lime, 6.7 kil. of magnesia, 6.5 

 kil. of potash and soda, 6.9 kil. of silica, 18.6 kil. of 

 oxide of iron and alumina ; no crop takes from the 

 soil so large a quantity of iron and sulj A 



This may be added to the subjects of experiment, 

 of which another year will show the result. In the
