Examine the roots of clover, peas, or beans, and look for nodules.
They develop in the nodules found on the feeding roots of the plants.
Nodules may be found in the liver, in the spleen, and in the kidneys.
The forms were also suggested by those of the nodules out of which they were made.
Sometimes isolated impressions are found in clay balls or nodules.
Many rocks have such holes, from the weathering out of nodules.
These nodules are essential to the normal growth and development of the plant.
These are comparable in general characters to the nodules on roots.
The nodules, after being washed, are ground to powder in a mill, and mixed with an equal weight of oil of vitriol.
Nodules may also form under the serous covering of the intestines.
