The excess of mineral matter is due to the mineral matter in the water
drank by the animals.

The following tables of analyses are copied in full from the last
edition (1875), of Dr. Emil Wolff's _Praktische Duengerlehre_.

The figures differ materially in many cases from those previously
published. They represent the average results of numerous reliable
analyses, and are sufficiently accurate for all practical purposes
connected with the subject of manures. In special cases, it will be
well to consult actual analyses of the articles to be used.
