 sion in the Peruvian Andes, near to Lima, and to collect a good 

 many plants of the middle and higher regions. Finding that my 

 collections include a fair proportion of undescribed species, and

 great range of the Andes, I offer to the Linnean Society an enu- 

 meration of the species collected, with brief descriptions of those 

 hitherto undescribed, and of some remarkable varieties, with a few 

 preliminary observations on the general character and possible 

 origin of the flora.

 between Chili and Peru, it was necessary for me to keep within 

 the portion of the territory occupied by the Chilian forces. This 

 fortunately included the remarkable line of railway destined to 

 connect Lima with the interior by the valley of the Eimac, and 

 the pass leading thence to Oroya, which lies on the eastern side 

 of the highest range of the Andes. Before the collapse of the 

 finances and regular administration of the government of Peru, 

 the line had been completed and opened as far as Chicla, the
