*' This is the case with the whole of the table land, where the 

 " vegetation lasts only for three months during the rainy season, 

 4< and, unless I can find out a place of constant verdure, my re- 

 <c searches will again prove as unsuccessful as during the last year. 



" On the 14th instant I left with Mr. Henderson, Zacatecas, a 

 " box marked H.S. 11, with the few things I have been able to col- 

 " lect ; it contains 10 kinds of seeds (and a few of Tropasolum pere- 

 " grinum from a Garden), two kinds of Cacti from Zacatecas, two 

 " bundles of duplicate specimens collected during the last year, and 

 " a cake of clay containing the seeds of a species of Magnolia, of 

 " which a similar quantity is placed in paper to see which would 

 " arrive safest." 



The box No. 11, arrived with the preceding seven. The Cacti 

 are both now alive ; of the 12 sorts of seeds, two only, Acacia 

 filicina, and a Convolvulaceous plant, germinated. The Magnolia 

 was dead in both instances. 



No. 20.— Morelia, (Valladolid) July 22nd, 1838. — " I arrived 

 " here about a month ago, and on the various excursions I made in 

 " the neighbouring mountains I found some most valuable plants. 

 " The Sierra here bears a great resemblance to that of Bolanos, 

 " it is well covered with Pines and Oaks, which latter are adorned 

 " with Orchidaceae of which I have secured 18 species, the greatest 

 " part of them new, four kinds of bulbs, a Cypripedium surpassing 

 " C. macranthum, an Arbutus, the tall species of Garrya, Pinus 

 " occidentalis, a species of Tilia and a most beautiful broad leaved 

 " Fuchsia, but I found of the latter, only two ripe capsules. 



" The herbarium consists the same as last year of 20 sets and of 

 " 27 species at present, having before my arrival here not been able 

 " to increase it much. 



" I soon must leave this place, the country particularly to the S.W. 

 " being exceedingly insecure, the pronunciados roving about in 

 " bands of from twenty-five to three hundred men, robbing every 

 " traveller of his arms, horse, and even the clothes on his back."
