LENTIL.

Among the leguminous plants which supply food for the invalid, and are endowed with certain qualifications for correcting the health, may be justly placed the Lentil, though we have to import it because our moist, cold climate is not favourable for its growth. Nevertheless, it closely resembles the small purple vetch of our summer hedgerows at home. In France its pulse is much eaten during Lent--which season takes its name, as some authors suppose, from this penitential plant. Men become under its subduing dietary influence, "lenti et lenes." The plant is cultivated freely in Egypt for the sake of the seeds, which are flat on both sides, growing in numerous pods.

The botanical name is Ervum lens; and about the year 1840 a Mr. Wharton sold the flour of Lentils under the name of Ervalenta, this being then of a primrose colour. He failed in his enterprise, and Du Barry took up the business, but substituting the red Arabian Lentil for the yellow German pulse.

Joseph's mess of pottage which he sold to Esau for his birthright was a preparation of the red Lentil: and the same food was the bread of Ezekiel.

The legumin contained in this vegetable is very light and sustaining, but it is apt to form unwholesome combinations with any earthy salts taken in other articles of food, or in the water used in cooking; therefore Lemon juice or vinegar is a desirable addition to Lentils at table. This is because of the phosphates contained so abundantly, and liable to become deposited in the urine. "Lentils," says Gerard, "are singular good to stay the menses." They are traditionally regarded as funeral plants, and formerly they were forbidden at sacrifices and feasts.

Parkinson said, "The country people sow it in the fields as food for their cattle, and call it 'tills', leaving out the 'lent', as thinking that word agreeth not with the matter." "Ita sus Minervam." In Hampshire the plant is known as "tils," and in Oxfordshire as "dills." The Romans supposed it made people indolent and torpid, therefore they named the plant from lentus, slow.

Allied to the Lentil as likewise a leguminous plant is the LUPINE, grown now only as an ornament to our flower beds, but formerly cultivated by the Romans as an article of food, and still capable of usefulness in this capacity for the invalid. Pliny said, "No kind of fodder is more wholesome and light of digestion than the white Lupine when eaten dry." If taken commonly at meals it will contribute a fresh colour and a cheerful countenance. When thus formerly used neither trouble nor expense was needed in sowing the seed, since it had merely to be scattered over the ground without ploughing or digging. But Virgil designated it tristis Lupinus, "the sad Lupine," probably because when the pulse of this plant was eaten without being first cooked in any way so as to modify its bitter taste, it had a tendency to contract the muscles of the face, and to give a sorrowful appearance to the countenance. It was said the Lupine was cursed by the Virgin Mary, because when she fled with the child Christ from the assassins of Herod, plants of this species by the noise they made attracted the attention of the soldiers.

The Lupine was originally named from lupus, a wolf, because of its voracious nature. The seeds were used as pieces of money by Roman actors in their plays and comedies, whence came the saying, "nummus lupinus," "a spurious bit of money."

LETTUCE.

Our garden Lettuce is a cultivated variety of the wild, or strong-scented Lettuce (Lactuca virosa), which grows, with prickly leaves, on banks and waysides in chalky districts throughout England and Wales. It belongs to the Composite order of plants, and contains the medicinal properties of the plant more actively than does the Lettuce produced for the kitchen. An older form of the name is Lettouce, which is still retained in Scotland.

Chemically the wild Lettuce contains lactucin, lactucopricin, asparagin, mannite, albumen, gum, and resin, together with oxalic, malic, and citric acids; thus possessing virtues for easing pain, and inducing sleep. The cultivated Lettuce which comes to our tables retains these same properties, but in a very modified degree, since the formidable principles have become as completely toned down and guileless in the garden product as were the child-like manners and the pensive smile of Bret Harte's Heathen Chinee.

Each plant derives its name, lactuca, from its milky juice; in Latin lactis; and in Greek, galaktos (taking the genitive case). This juice, when withdrawn from the cut or incised stalks and stems of the wild Lettuce, is milky at first, and afterwards becomes brown, like opium, being then known (when dried into a kind of gum) as lactucarium. From three to eight grains of this gum, if taken at bedtime, will allay the wakefulness which follows over-excitement of brain. A similar lactucarium, got from the dried milk of the cultivated garden Lettuce, is so mild a sedative as to be suitable for restless infants; and two grains thereof may be safely given to a young child for soothing it to sleep.

The wild Lettuce is rather laxative; with which view a decoction of the leaves is sometimes taken as a drink to remedy constipation, and intestinal difficulties, as also to allay feverish pains. The plant was mentioned as acting thus in an epigram by Martial (Libr. VI., Sq.).

"Prima tibi dabitur ventro lactuca movendo Utilis, et porris fila resecta suis."

Gerard said: "Being in some degree laxative and aperient, the cultivated Lettuce is very proper for hot bilious dispositions;" and Parkinson adds (1640): "Lettuce eaten raw or boyled, helpeth to loosen the belly, and the boyled more than the raw." It was known as the "Milk Plant" to Dioscorides and Theophrastus, and was much esteemed by the Romans to be eaten after a debauch of wine, or as a sedative for inducing sleep. But a prejudice against it was entertained for a time as venerem enervans, and therefore mortuorum cibi, "food for the dead."

Apuleius says, that when the eagle desires to fly to a great height, and to get a clear view of the extensive prospect below him, he first plucks a leaf of the wild Lettuce and touches his eyes with the juice thereof, by which means he obtains the widest perspicuity of vision. "Dicunt aquilam quum in altum volare voluerit ut prospiciat rerum naturas lactucoe sylvaticoe folium evellere et succo ejus sibi oculos tangere, et maximam inde claritudinem accipere."

After the death of Adonis, Venus is related to have thrown herself on a bed of lettuces to assuage her grief. "In lactuca occultatum a Venere Adonin--cecinit Callimachus--quod allegorice interpretatus Athenoeus illuc referendum putat quod in venerem hebetiores fiunt lactucas vescentes assidue."

The Pythagoreans called this plant "the Eunuch"; and there is a saying in Surrey, "O'er much Lettuce in the garden will stop a young wife's bearing." During the middle ages it was thought an evil spirit lurked among the Lettuces adverse to mothers, and causing grievous ills to new-born infants.

The Romans, in the reign of Domitian, had the lettuce prepared with eggs, and served with the last course at their tables, so as to stimulate their appetites afresh. Martial wonders that it had since then become customary to take it rather at the beginning of the meal:--

"Claudere quae caenas lactuca solebat avorum Dic mihi cur nostras inchoat illa dapes."

Antoninus Musa cured Caesar Augustus of hypochondriasis by means of this plant.

The most common variety of the wild Lettuce, improved by frequent cultivation, is the Cabbage Lettuce, or Roman, "which is the best to boil, stew, or put into hodge-podge." Different sorts of the Cos Lettuce follow next onwards. The Lactuca sylvatica is a variety of the wild Lettuce producing similar effects. From this a medicinal tincture (H.) is prepared, and an extract from the flowering herb is given in doses of from five to fifteen grains. No attempt was made to cultivate the Lettuce in this country until the fourth year of Elizabeth's reign.

When bleached by gardeners the lettuce becomes tender, sweet, and succulent, being easily digested, even by dyspeptic persons, as to its crisp, leafy parts, but not its hard stalk. It now contains but little nutriment of any sort, but supplies some mineral salts, especially nitre. In the stem there still lingers a small quantity of the sleep-inducing principle, "lactucarin," particularly when the plant is flowering. Galen, when sleepless from advanced age and infirmities, with hard study, took decoction of the Lettuce at night; and Pope says, with reference to our garden sort:--

"If you want rest, Lettuce, and cowslip wine:--'probatum est.'"

But if Lettuces are taken at supper with this view of promoting sleep, they should be had without any vinegar, which neutralises their soporific qualities. "Sleep," said Sir Thomas Brown, "is so like death that I dare not trust it without my prayers."

Some persons suppose that when artificially blanched the plant is less wholesome than if left to grow naturally in the garden, especially if its ready digestibility by those of sensitive stomachs be correctly attributed to the slightly narcotic principle. It was taken uncooked by the Hebrews with the Paschal lamb.

John Evelyn writes enthusiastically about it in his Book of Sallets: "So harmless is it that it may safely be eaten raw in fevers; it allays heat, bridles choler, extinguishes thirst, excites appetite, kindly nourishes, and, above all, represses vapours, conciliates sleep, and mitigates pain, besides the effect it has upon the morals-- temperance and chastity."

"Galen (whose beloved sallet it was) says it breeds the most laudable blood. No marvel, then, that Lettuces were by the ancients called sanoe by way of eminency, and were so highly valued by the great Augustus that, attributing to them his recovery from a dangerous sickness, it is reported he erected a statue and built an altar to this noble plant." Likewise, "Tacitus, spending almost nothing at his frugal table in other dainties, was yet so great a friend to the Lettuce that he used to say of his prodigality in its purchase, Summi se mercari illas sumitus effusione." Probably the Lettuce of Greece was more active than our indigenous, or cultivated plant.
