Glands are congeries of vessels in which fluids of various kinds are elaborated, and it is partly from these fluids or those from which they are formed, stagnating in their vessels, owing to want of vital action, that the swelling arises, which is always found in scrofulous subjects. That sluggish disposition of these parts is generally connected with a languid and lax state of the general system, which is liable to be greatly increased by whatever diminishes the vigour of the body. Few circumstances are better calculated to produce that effect than insufficient food, and hence it is that those diseases whose foundation is a scrophulous taint, are so much promoted in times of scarcity, and among individuals accustomed to a liberal diet when accidentally placed on scanty fare. Instances are known where persons have become affected with weak eyes, with tenderness, watering and disposition to ulceration in these organs, immediately upon being put on spare and poor diet, and where a liberal supply of nutritious food has proved an almost immediate cure. That affection of the eyes was a form of scrophula, and fortunate it was for them that the form in which that disease manifested itself was not more dangerous. They had much reason to be thankful that the injury was capable of cure, and was not irremediable, as it has been in many instances, where the first intimation of the bad consequences of a scanty and insufficient diet has been decided and incurable consumption of the lungs. When the glands which assume the scrofulous action are those of the lungs, and when they become the seat of the formation of matter, pulmonary consumption is said to be produced, a disease which annually carries off a great proportion of the adult population of this country. Consumption of the lungs, or pulmonary consumption, is a common affection among those who subsist on scanty and insufficient food, and is frequently observed with dogs and other animals whose sustenance is small and precarious. Scrophula manifests itself in other forms, not less severe and extremely loathsome—in running sores on the neck and other parts, in swellings of the joints, and in various wasting diseases of the bones and their coverings. In the various forms which this disease assumes, the blood and the different humours of the body become unhealthy and often acrimonious. The milk of nurses who are tainted with that habit is unwholesome, and when they are made to subsist on scanty and insufficient diet, it becomes poor, less nutritious, and positively injurious—and instead of being bland and white, it often appears watery and yellowish, and is irritating and acrimonious. Food of an unwholesome or vitiated quality is also injurious, and has on many occasions proved to be the cause of much disease. Plants as well as animals are subject to disease, and food when obtained from such sources is highly unwholesome and detrimental to health.
