The fur is thick and soft, with very Uttle lustre, in texture very 

 like that of V. Chiloensis. That of the upper parts is nearly uni- 

 coloured, of a deepish ferruginous hue, a little darker at the root 

 than at the tip. Below, it is bicoloured, dark brown at the base, 

 tipped with greyish brown, paler and unicoloured on the pubes. 

 The dentition has not been examined.

March 11, 1858. — Professor Balfour, V.P., in the Chair. 

 The following papers were read : — 



1 . "A few Remarks on the Application of Photography to Botani- 

 cal Purposes," by Charles J. Burnett, Esq. 



2. " Critical Remarks on the genus Orthotrichum ^Part II.)," by 

 Dr. Benjamin Carrington. 



In this second part of his paper. Dr. Carrington gave a detailed 

 description of the various British species of Orthotrichum, and en- 

 tered upon a discussion of their specific distinctions, especially with 

 reference to those species that have of late years been added to the 

 British flora.

I. Gutta Percha of Surinam. — Prof. Bleckrod of the Delft Aca- 

 demy has recently given a notice of the Gutta Percha of Surinam. 

 The Professor states that Dutch Guiana can supply gutta percha. 

 The Dutch Government took measures to trans])lant the Isonanclra 

 Gutta and cultivate it in Guiana ; but they have lately discovered in 

 that country a species of Sapota, to which Blume gives the name of 

 Sapoto Mulleri, which yields a juice in every way equal to that of 

 the Isonandra. It is probable that other trees of the same natural 

 order may be found to yield a similar product. Achras Sapota, the 

 fruit of which is known in the West Indies as "Neesberry," also yields 

 a milky juice like gutta percha. The Sapota Mulleri of Blume is 

 probably the tree called " Bullet-tree" by the English, and its wood 

 is known as " horse-flesh." It is a tall tree, yielding in sumn)er a 

 large quantity of milky juice. It appears that, luidcr the name of 

 common Boerowe or Bullet-tree, there have been confounded —
