Viper's Bugloss (Echium vulgare), the flowering tops of which were recommended for the hite of the viper ; 

 Gromwell (JLithospermu7n officinale), commonly termed Pearlwort, on account of its hard and pearl-grey 

 nucules, which were supposed to be of use in dissolving bladder-stones; and Heliotropium europemm, of which 

 the bitter and salt leaves were applied to ulcers and warts. Tournefortia umbellata is still used in Mexico 

 as a febrifuge. In tropical America and in India certain species of Tiaridium are used in herpetic affec- 

 tions. Some EhretieeB have an edible fruit. Finally, the roots of several species of Anchiisa, Onosma, 

 Lithnspernmm, Amelia, contain a red colouring matter, soluble in alcohol and fatty bodies, which is em- 

 ployed to colour certain unguents and other external applications.
