This affection is also undoubtedly catarrhal in character. It is closely allied to cholera morbus, and is probably essentially the same disease, being modified by the age, and the character of the food upon which children are usually fed when they are most susceptible to the disease. It is quite probable that the great cause of the disease in children is the fermentation and decomposition of food in the stomach. This may be due to slowness of the digestion, to overloading the stomach, or to feeding with milk which has begun to sour, or has begun fermentation through inattention to thorough cleanliness in the care of the nursing-bottle, neglect to wash the child's mouth, etc. The disease is frequently preceded in children by a diarrhea, which often continues for several days before the disease makes its appearance.
At the beginning of vomiting, the milk thrown up is in a fluid condition instead of being well coagulated as is the case in health, which shows that the stomach is not active, there being little or no secretion of gastric juice. This is frequently a fatal disease, especially when it attacks young infants, or those who are of a feeble constitution.
