1043. Nitre—Saltpetre.—This, in over-doses, produces violent poisonous symptoms. Vomiting should be immediately induced by large doses 441 of mucilaginous, diluent drinks; but emetics which irritate the stomach should not be given.

1035. What is the antidote? 1036. What should immediately be done when arsenic is swallowed? 1037. What is the antidote? Can any quantity of this preparation of iron be given without injurious results? 1038. What should be given when verdigris has been taken into the stomach? 1039. What is the antidote? 1040. What should immediately be given when sugar of lead is taken? 1041. What is the antidote? 1042. Give the treatment when corrosive sublimate has been swallowed. 1043. What effect has an over-dose of saltpetre? What treatment should be adopted?

1044. Zinc.—Poisoning is sometimes caused by the sulphate of zinc, (white vitriol.) When this takes place, vomiting should be induced, and aided by large draughts of mucilaginous and diluent drinks. Use the stomach-pump as soon as possible.

1045. The antidote is the carbonate, or super-carbonate of soda.

1046. Nitric, (aqua fortis,) MURIATIC, (MARINE ACID,) OR SULPHURIC (OIL OF VITRIOL,) ACIDS, may be taken by accident, and produce poisonous effects.

1047. The antidote is calcined magnesia, which should be freely administered, to neutralize the acid and induce vomiting. When magnesia cannot be obtained, the carbonate of potash (salæratus) may be given. Chalk, powdered and given in solution, or strong soap suds, will answer a good purpose, when the other articles are not at hand. It is of very great importance that something be given speedily, to neutralize the acid. One of the substances before mentioned should be taken freely, in diluent and mucilaginous drinks, as gum-water, milk, flaxseed, or slippery-elm tea. Emetics ought to be avoided.

1048. Oxalic Acid.—This acid resembles the sulphate of magnesia, (epsom salts,) which renders it liable to be taken, by mistake, in poisonous doses. Many accidents have occurred from this circumstance. They can easily be distinguished by tasting a small quantity. Epsom salts, when applied to the tongue, have a very bitter taste, while oxalic acid is intensely sour.

1049. The antidote is magnesia, between which and the acid a chemical action takes place, producing the oxalate of magnesia, which is inert. When magnesia is not at hand, chalk, lime, or carbonate of potash, (salæratus,) will answer as a substitute. Give the antidote in some of the mucilaginous drinks before mentioned. No time should be lost in introducing the stomach-pump as soon as a surgeon can be obtained.

1050. Ley.—The ley obtained by the leaching of ashes may be taken by a child accidentally. The antidote is vinegar, or oil of any kind. The vinegar neutralizes the alkali by uniting with it, forming the acetate of potash. The oil unites with the alkali, and forms soap, which is less caustic than the ley. Give, at the same time, large draughts of mucilaginous drinks, as flaxseed tea, &c.

1044. What is the antidote for white vitriol? 1047. What is the antidote for aqua fortis and oil of vitriol? Should emetics be avoided? 1048. How can oxalic acid be distinguished from epsom salts? 1049. What is the antidote for an over-dose of oxalic acid? When magnesia cannot be obtained, what will answer as a substitute? 1050. What is the antidote when ley is swallowed?

1051. The vegetable poisons are quite as numerous, and many of them equally as virulent, as any in the mineral kingdom. We shall describe the most common, and which, therefore, are most liable to be taken.

1052. Opium.—This is the article most frequently resorted to by those wishing to commit suicide, and, being used as a common medicine, is easily obtained. From this cause, also, mistakes are very liable to be made, and accidents result from it. Two of its preparations, laudanum and paregoric, are frequently mistaken for each other; the former being given when the latter is intended.

1053. Morphia, in solution, or morphine, as it is more commonly called by the public, is a preparation of the drug under consideration, with which many cases of poisoning are produced. It is the active narcotic principle of the opium; and one grain is equal to six of this drug in its usual form.

1054. When an over-dose of opium, or any of its preparations, has been swallowed, the stomach should be evacuated as speedily as possible. To effect this, a teaspoonful of ground mustard seed, or as much tartar emetic as can be held on a five cent piece, or as much ipecacuanha as can be held on a twenty-five cent piece, should be mixed in a tumbler of warm water, and one half given at once, and the remainder in twenty minutes, if the first has not, in the mean time, operated. In the interval, copious draughts of warm water, or warm sugar and water, should be drank.

1055. The use of the stomach-pump, in these cases, is of the greatest importance, and should be resorted to without delay. After most of the poison has been evacuated from the stomach, a strong infusion of coffee ought to be given; or some one of the vegetable acids, such as vinegar, or lemon-juice, should be administered.

1056. The patient should be kept in motion, and salutary effects will often be produced by dashing a bucket of cold water on the head. Artificial respiration ought to be established, and kept up for some time. If the extremities are cold, apply warmth and friction to them. After the poison has been evacuated from the stomach, stimulants, as warm wine and water, or warm brandy and water, should be given, to keep up and sustain vital action.

1057. Stramonium—Thorn-Apple.—This is one of the most active narcotic poisons, and, when taken in over-doses, has, in numerous instances, caused death.

1051. Are vegetable poisons as numerous and as virulent in their effects as mineral? 1052. What is said of opium and its preparations? 1054, 1055, 1056. What treatment should be adopted when an over-dose of opium or any of its preparations is taken? 1057. What is said of stramonium?

1058. Hyosciamus—Henbane.—This article, which is used as a medicine, if taken in improper doses, acts as a virulent irritating and narcotic poison.

1059. The treatment for the two above-mentioned articles is similar to that of poisoning from over-doses of opium.

1060. Conium—Hemlock.—Hemlock, improperly called, by many, cicuta, when taken in an over-dose, acts as a narcotic poison. It was by this narcotic that the Athenians used to destroy the lives of individuals condemned to death by their laws. Socrates is said to have been put to death by this poison. When swallowed in over-doses, the treatment is similar to that of opium, stramonium, and henbane, when over-doses are taken.

1061. Belladonna—Deadly Nightshade.—Camphor. Aconite—Monkshood, Wolfsbane. Bryonia—Bryony. Digitalis—Foxglove. Dulcamara—Bittersweet. Gamboge. Lobelia—Indian Tobacco. Sanguinaria—Bloodroot. Oil of Savin. Spigelia—Pinkroot. Strychnine—Nux vomica. Tobacco.—All of these, when taken in over-doses, are poisons of greater or less activity. The treatment of poisoning, by the use of any of these articles, is similar to that pursued in over-doses of opium. (See Opium, page 442.)

1062. In all cases of poisoning, call a physician as soon as possible.

1058. Of henbane? 1059. What should be the treatment when an over-dose of stramonium or henbane is taken? 1060. What name is sometimes improperly given to conium, or hemlock? How was this narcotic poison used by the Athenians? How are the effects of an over-dose counteracted? 1061. What is the treatment when an over-dose of deadly nightshade, monkshood, foxglove, bittersweet, gamboge, lobelia, bloodroot, tobacco, &c., is taken? 1062. Should a physician be called in all cases when poison is swallowed? 444

The essential parts of every secretory apparatus are a simple membrane, apparently textureless, named the primary, or basement membrane, certain cells and blood-vessels. The serous and mucous membrane are examples.

The division and description of the different membranes and tissues are not well defined and settled by anatomical writers. This is not a material defect, as a clear description of the different parts of the system can be given by adopting the arrangement of almost any writer.

Fat is one of the non-nitrogenous substances. It forms the essential part of the adipose tissue. Chemical analysis shows that all fatty substances are compounds of carbon, hydrogen, and oxygen. They are lighter than water, generally fluid at the natural temperature of the body, and burn with a bright flame, forming water and carbonic acid.

Caseine is abundantly found in milk. When dried, it constitutes cheese. Alcohol, acids, and the stomach of any of the mammalia coagulate it; and it is also soluble in water. It is found in the blood, bile, saliva, and the lens of the eye.

Chondrine is a variety of gelatin. It is obtained from cartilage. It is soluble in warm water, but solidifies on cooling.

Lactic acid is common to all the solids and fluids of the system. It is found united with potash, soda, lime, or magnesia.

The word duodenum is derived from the Latin, signifying “twelve,” since the intestine, of which this is the name, is usually about twelve fingers’ breadth in length. The jejunum is also from the Latin jejunum, empty, since it is usually found in that condition after death, as the food seems to pass rapidly through this part of the intestine. The term ileum is from the Greek, signifying “to twist,” since it always appears in a contorted condition. The name cæcum is derived from the fact of its being a blind or short sack, perforated by the extremity of the ileum. The name of the next division of the intestine—colon—is from the Greek, “to prohibit,” as the contents of the alimentary canal pass slowly through this portion. The rectum is named from the straight direction that it assumes in the latter part of its course.

The food is forced through the alimentary canal by contractions of its muscular coat, produced by the nervous filaments of the sympathetic system, not being at all dependent on the cerebro-spinal centre. This is called the peristaltic, or vermicular motion. The great length of intestine in all animals, and especially in the herbivorous ones, is owing to the necessity of exposing the food to a large number of the lacteals, that the nourishment may all be taken from it.

The different processes through which the food passes before assimilation are of considerable interest. The mastication and mixture of the saliva with the food are purely of a mechanical nature. When any solid or fluid substance is placed upon the tongue, or in contact with the inner surface of the cheeks, by an involuntary act, the salivary glands are stimulated to activity, and commence pouring the saliva into the mouth through the salivary ducts. As soon as mastication commences, the contraction of the masseter and other muscles employed in mastication stimulates the salivary glands to increased action, and a still greater quantity of saliva is secreted and forced upon the food, which is constantly being ground to a finer condition, until it is sufficiently reduced for deglutition.

Whether the salivary fluid acts any other part than simply that of a demulcent to assist the gastric juice in still further dissolving the food, is yet a matter of some doubt, although it is found that no other liquid will equally well subserve the process of digestion and promote health.

After the food is in the condition ready to be swallowed, by an apparently involuntary motion, it is placed upon the back
