The relations between lactation, menstruation, impregnation, etc., are not well understood. That which was thought to be fact in the past is proving to be fallacious. Jacobius inquired carefully into one hundred and eighty cases of nursing women where menstruation occurred at the sixth month. The most of the infants showed transient disturbance, with a tendency to diarrhea and imperfect digestion. Occasionally there was vomiting, but in most of the cases the conditions were corrected and the children thrived.
It is a common belief that pregnancy disturbs the character of the milk, and that infants nursing suffer severely therefrom. This is undoubtedly true in many cases, but the condition can be corrected, and often, if the mother can stand the drain, the child does as well afterward as before.
I should like very much to have reports of observations made in the lines above suggested.
