CULTIVATION OF THE INK PLANT IN EUROPE. 



For many years the juice of the ink plant {Coriaria thym- 

 ifolium) has been used in South America as an ink, as it 

 flows freely from the pen, and, although of a reddish color 

 at first, becomes very black in a few hours. It does not 

 attack steel pens, and is said to be absolutely ineffaceable. 

 Quite recently attention has been drawn to its superior prop- 

 erties, and extensive efforts are now being initiated in Paris 

 and elsewhere in Europe for the purpose of multiplying this 

 plant, and bringing it into general use. 1 A, July 12,1872,23. 



DIFFERENT CUNDURANGO PLANTS. 



Professor Triana, as the result of a careful inquiry into the 

 medicinal character of cundurango, has decided that the form 

 so strongly recommended of late as a remedy for cancer con- 

 stitutes an undescribed species of the genus Gonolobus, which 

 he has named G. cundurango. Another plant, likewise called 

 cundurango, and found in the high lands of New Granada, is 

 properly known as the Macroscepis triance of Decaisne ; while 

 still another, sometimes called Cundurango, but more prop- 

 erly Guaca or Gaucho, also from New Granada, is the Mi- 

 kania guaco. This latter plant has a high reputation in its 

 own country as a cure for the bite of a serpent, for which it 

 is considered infallible. 4 B, August, 1872, 050.
