![Jambul, or Syzygium Jambolana—The seeds of this myr- taceous tree have been introduced by Bamatvala, and tried in diabetes by Fenwick, Saundby, Caldwell, and others, and in some cases with no result, whilst in others the remedy was beneficial to an unexpected extent. Dr. Kingsbury found in one case that the urine fell from ]\ to 4^ quarts, and Fenwick reports a case where, in one week, sloughing ulcers rapidly healed and the urine fell to one-half after 2\ gr. powdered seeds three times a day. Double this amount may be given. It has been proved that the drug has a marked power in diminishing phloridzin diabetes in dogs. The fruit is used in India as an astringent in dysentery and diarrhcea. Jatropha Curcas—The seeds of this Euphorbiacious plant yield on expression an oil of rather pleasant flavour, which has been extensively tried in Southern America and India as a purgative. 15 minims of this fixed oil produce active purgation, said to be equal to about i oz. of castor oil. The great disadvantage possessed by castor oil is its bulkiness, which prevents its being administered in capsules. The oil of jatropha, if found otherwise unobjectionable, may prove of great con- venience. Jequirity Seeds (Abrus Precatorius)—Since the scarlet seeds known as prayer beads and jumble beads were introduced by Wecker for producing what is now known as Jequirity Ophthal- mia much has been written upon them. Sattler using a ^ to I per cent, active fresh infusion prepared by macerating the bruised seeds deprived of their coats, in cold water for 24 hours, filtering and applying at once to the conjunctiva, describes the application itself as painless. After three hours—the period of incubation— symptoms of severe ophthalmia begin, which reaches its height in about 30 hours. There is intense inflammation, pain, heat, redness, and oedema, with the development of a thick adherent croupous membrane, which separates from the conjunctiva about the third day, but which is reproduced at intervals for three days more. There is profuse purulent secretion, and generally some weeks elapse before the last traces of redness, unevenness, and dirty yellow discoloration pass off. The infusion swarms with a peculiar microzyme, to which the effects of the drug have been attributed. This bacillus has been seen in the purulent secretion, and Sattler affirms that a little of the secretion will produce a conjunctivitis like the original, only much milder. lie cultivated the bacillus through several generations. Bechamp and Dujardin have cultivated the bacillus, and upon injecting it into the veins found that it produced death ^ike jequirity. Klein produced the typical ophthalmia by a .crilised infusion, devoid of the jequirity bacillus, and he com-](https://iiif.wellcomecollection.org/image/b20417846_0549.jp2/full/800%2C/0/default.jpg)
