In the parterre, which is in the Italian style, and situated 

 before the green-house, there is a rich collection of roses, 

 amongst which there are several of great beauty, procured by 

 the present director, Giovanni Casoretti, whose abilities, intel- 

 ligence, and politeness are beyond eulogium. The names of 

 these roses are as follows : — Hayez, Traversi, MafFeis, Strambio, 

 Cabrisi, Byron, Rossini, la rose tendre, la Padulli, la marchese, 

 la color di paglia, la trompeuse, la belle Judith, I'Elodie, la 

 Bartolotti, and la Pirzi. There are a Magnolm pyramidata, 12 ft. 

 hioh, which branches out from its base ; Magnolm auriculata, 

 16 ft. high, with a trunk which measured, at 1 ft. from the ground, 

 7^ in. in circumference ; and a Magnolm grandiflora magordensis, 

 which appears to me to be a hybrid, not very distinct from 

 M. grandiflora prae^cox ; the only properties which distinguish 

 it being, as I am told, that the flower is rather larger than that 

 of M. g. prae^cox, and expands rather later. To tell the truth, I 

 have never seen it in flower myself; but I have written to 

 Signor Casoretti to send me one when they are in their full 

 beauty, in order that I may compare it with those of M. g. prse'cox. 

 It is 15 ft. high, with a trunk 9 in. in circumference. Mag- 

 \-\6\ia gracilis is 10 ft. high, branching out from its base, and 

 occupying a space of 22 ft. in circumference. Magnol/a macro- 

 phylla is 20 ft. high, with a trunk 1 1 in. in circumference, and the 

 head 10 ft. in diameter. Last year this beautiful plant produced 

 and ripened seeds; and this spring more than 150 plants were 

 produced from it, amongst which Signor Casoretti hopes to 

 obtain new varieties, having fecundated some of the flowers with 

 the pollen of M. purpurea and M. conspicua. About eight 

 years ago, Signor Casoretti obtained a variety of M. obovata 

 (M. purpurea), which has all the characteristics of its parent 

 except that it is only a foot and a half high, and which he therefore 

 calls M. obovata pumila. 



The pine-apple stoves which have lately been constructed 

 are still heated by the old method, that is, by flues ; and about
