I found these two species pentifully in the North; but no- 
where in greater plenty or perfection than on Brigstear Moss, 
near Kendal, where they grow to twice or thrice the size they 
usually acquire with us; but in other respects appeared to me 
to afford no truly specific character. It is very probable that the 
three species enumerated in Ray, in addition to the above, will 
be found to be varieties only. 
[Nos. 21, 23, 24, 25, 29, 31, 33, 34, 35, 38, 39, 40, 41 were

Three parts of this grand work are already published, and the 
remainder will follow at the rate of one part, monthly, till the 
whole is completed. We have seen two of these monthly delive- 
ries, and have much pleasure in laying before our readers an ac- 
count of one of the most magnificent contributions to British 
botany that has hitherto appeared. Indeed it may he said that 
since the publication of the ‘ Illustrations of the Genus Pinus,’ 
by A. B. Lambert, Esq., no botanical work, comparable to this, 
has appeared in Great Britain. We have not space to enter into 
the merits of nature printing, nor to explain its capabilities of 
representing external forms with perfect accuracy, even to the 
minutize of veins, hairs, and other superficial accessories, whereby 
plants are chiefly distinguishable from each other. This the edi- 
tors have done in the preface to the work, and to this we refer
