Another compound was formed by using 
ferro-cyanodide of calcium instead of the salt 
of potash. 7’he constituents were, iron 18'24, 
magnesium 8-93, ammonia 11'43, cyanogen 
53‘91, water 7'49, abstracting the lime which 
was found in it. Tliis is equivalent to (Fe Cy 
+2 Mg Cy) + Fe Cy + NIP) + 2 HO.-

All these papers, with the exception of the 
two last amounting to six pages, were read 
before the Linnean Society in 1832. The 
quality, however, of the materials of which 
this volume is composed does not produce the 
same disappointment which is experienced in 
reference to the quantity. We may refer more 
particularly to Esenbeck’s Monograph, and 
the distinguished De Candolle’s review, for 
the materials of both of which we are indebt- 
ed to the industry of Dr. Wallick and the 
munificence of the East India Company. It 
is remarkable, however, that of 145 pages, of 
which the volume consists, 90 are written by 
foreigners. 1 conceive that a short outline of 
these papers will be highly acceptable to those 
who may not have an opportunity of reading 
the transactions themselves.

common peduncle.

common peduncle ; 3. S Rubrum.

20. Has been named in honour of the in- 
defatigable Dr. Wight of Aladras, who for 
some time has employed painters and collec- 
tors at his own expense, for the purpose of 
elucidating the botany of Madras. 
25. Under this species Esenbeck includes 
the S diffusum of Roxburgh, It is an abun- 
dant plant in Madras and Bengal, and 1 have 
found it occurring plentifully in the neigh- 
bourhood of Bombay. 
30. This merely refers to the potatoe as 
cultivated in Madras and Bengal. It does 
not attain any considerable size in the hot 
parts of these presidencies, but near Bussorah 
I believe it thrives much better.

The paper of De Candolle does not require 
such a minute analysis as the species of the 
order Myrsinece, which he has therein illur- 
tiated, are all natives of foreign climates, and 
cannot, therefore, be so generally interesting 
as those of the order of Solanecc. A fcw facts 
may, however, be stated, which exhibit in a 
striking point of view the rapid progress which
