A writer under the signature CRITO in the “Truth Teller” dilates most pleasantly in his fourth letter concerning flowers and their names. He says “the pilgrimages and the travelling of the mendicant friars, which began to be common towards the close of the twelfth century, spread this knowledge of plants and of medical nostrums far and wide. Though many of these vegetable specifics have been of late years erased from our Pharmacopœias, yet their utility has been asserted by some very able writers on physic, and the author of these observations has himself often witnessed their efficacy in cases where regular practice had been unavailing. Mr. Abernethy has alluded to the surprising efficacy of these popular vegetable diet drinks, in his book on the ‘Digestic Organs.’ And it is a fact, curiously corroborating their utility, that similar medicines are used by the North American Indians, whose sagacity has found out, and known from time immemorial, the use of such various herbs as medicines, which the kind, hospitable woods provide; and by means of which Mr. Whitlaw is now making many excellent cures of diseases.” He then proceeds to mention certain plants noted by the monks, as flowering about the time of certain religious festivals: “The SNOWDROP, _Galanthus nivalis_, whose pure white and pendant flowers are the first harbingers of spring, is noted down in some calendars as being an emblem of the purification of the spotless virgin, as it blows about Candlemas, and was not known by the name of snowdrop till lately, being formerly called FAIR MAID OF FEBRUARY, in honour of our lady. Sir James Edward Smith, and other modern botanists, make this plant a native of England, but I can trace most of the wild specimens to some neighbouring garden, or old dilapidated monastery; and I am persuaded it was introduced into England by the monks subsequent to the conquest, and probably since the time of Chaucer, who does not notice it, though he mentions the daisy, and various less striking flowers. The LADYSMOCK, _Cardamine pratensis_, is a word corrupted of ‘our lady’s smock,’ a name by which this plant (as well as that of _Chemise de nôtre Dame_) is still known in parts of Europe: it first flowers about Lady Tide, or the festival of the Annunciation, and hence its name. CROSS FLOWER, _Polygala Vulgaris_, which begins to flower about the Invention of the Cross, May 3, was also called _Rogation flower_, and was carried by maidens in the processions in Rogation week, in early times. The monks discovered its quality of producing milk in nursing women, and hence it was called _milkwort_. Indeed so extensive was the knowledge of botany, and of the medical power of herbs among the monks of old, that a few examples only can be adduced in a general essay, and indeed it appears that many rare species of exotics were known by them, and were inhabitants of their monastery gardens, which Beckmann in his
