principle of vegetation prevents those changes of 

 colour which immediately take place when that 

 influence is destroyed. Unfortunately there is as 

 yet, I believe, no discovered mode of fixing the 

 representations so obtained, which, in their turn, 

 fade away on the admission of light ; but doubtless 

 the progress of science will ere long remedy this 

 deficiency. 



The yellow horned-poppy (P. glducum, or Gldu- 

 cium luted) of our sandy shores so named from 

 the protrusion of its long and horn-like pistil 

 abounds also on the shores of middle and southern 

 Europe, and on those of Virginia and Carolina, thus 

 shewing a very marked lateral zone of geographical 

 distribution. It is the " squabs " of the Portland 

 islanders. 



These horned-poppies however, of which we pos- 

 sess, in addition to the above, the following species : 

 the scarlet horned-poppy (Glducium Phcenlceum), 

 and the violet horned-poppy (G. violdceum), are no 

 longer considered genuine poppies, being separated 

 into a group termed Glaucium; in the same manner 

 as the following species is now recognised as belong- 

 ing to the genus Meconopsis. 



The Welsh poppy (Papdver, or Meconopsis Cdm- 

 bricum) is so named on account of its occurring 

 more abundantly in the Principality than in any 

 observed part of the world. It occurs, however, 

 in tolerable quantity on the Pyrenees, the French 

 Alps, and also on the river Jenisen in Kussia ; while 

 in England it is found at Cheddar, and near Ken- 

 clal ; as also in some parts of Ireland.
