 " Italian gentleman residing up there, together with some seeds of 

 " a white Rhododendron which was at the time of my visit in full 

 " flower." 



No. 12.— Bolahos, November llth, 1837.—" Your letter of the 

 " 19th of June last I only received on the 7th instant, and beg to 

 " acquaint you that I shall forward the articles I have hitherto 

 " been collecting for the Society as soon as I reach Zacatecas, 

 " where part of the seeds are ; the bulbs and terrestrial Orchidaceae
