4. " Notice of the production of Cones in 1851 onPinus Lumber- 

 tiana," by A. G. Spiers, Esq. The tree on which the cones were 

 produced was stated to be about 23 feet in height ; the cones con- 

 tained perfect seeds, from which young plants have been raised. 



Mr. M'Nab stated that several plants of Abies Morinda were 

 fruiting this season in different situations. He mentioned that all these 

 plants had grown in the Botanic Garden, and had been transplanted 

 last year. The large plants of the same pine which had not been 

 transplanted showed no symptoms of flowering.

8. " On Melampyrum montanum, Johnst.," by Daniel Oliver, jun., 

 Esq., F.L.S. "This plant, as described in the Berwickshire Flora, 

 and mentioned in Babington's ' Manual ' as a variety of M. pratense, 

 I am induced to beheve has been founded by Dr. Johnston on an ex- 

 amination of an insufficient series of examples of more or less distinct 

 forms of Melampyrum. 



" Last year I described in the ' Phytologist,' a plant which I called 

 M. pratense var. ericetorum, and in the same communication hinted 

 that its smaller forms might be identical with the M. montanum. 



" I am rather strengthened in this opinion by a series of specimens 

 which I collected last month near the Wall-town Crags, Northumber- 

 land. The floral leaves (bracts) are in some of the larger instances 

 of the plant, ovate-lanceolate or almost ovate at the base, and deeply 

 toothed, while the smaller ones accord more nearly with M. mon- 

 tanum."

In the circulation of these animals there is a much more compli-

 blood is not contained in tubes capable of isolation by dissection, it is 

 none the less confined to a particular course.
