is certain, aud the sign is only substituted for the omitted 

 number ' 18.' Still undetermined whether C. alpinum 

 or C. latifolium was the species seen by Dr. Neill in 

 Orkney.

The mean temperature of 46 will be too high ; that of 

 45 — 44 will probably be nearer truth, in accordance with 

 explanations made on page 4 of the second volume.

Province 3 to be added in the true area, on authority 

 of Mr. E. G. Varenne, who finds the species at Southend, 

 Essex. Dr. Bromfield (Phytol. iii. 276) refers to Dr. 

 Pulteney's list in the Hampshire Repository, as an autho- 

 rity for L. perenne in that county, but distrusts the 

 record himself. It may be safer to exclude provinces 

 [1] and [2] for the present. The county of Essex should 

 be indicated in the south limit, instead of Suffolk, on the 

 testimony of Mr. Varenne ; and the provincial census will 

 rise to 6. A*- /U^^^^ ^ 0^7 ^cam^ ^ -^W^^^ /i^ />f //h-u^ ■uc ^'^^-^ ><" .^^'^^

Province 6 to be added in the area, on authority of 

 Mr. Babington and other botanists. The pro\dncial area 

 thus becomes general.

The south limit may be extended to Cornwall, on the 

 authorities quoted by Mr. Pascoe, in Bot. Gaz. u. 39. 

 Mr. Alton enumerates it among the plants of North 

 Lancaster, so that perhaps province 12 may be added to 

 the true area.

The true distribution of this i)lant, present and native, 

 is still very imperfectly determined. The counties of 

 Cornwall, Devon, Somerset, Glamorgan, Pembroke, An- 

 glesea, seem to be best authenticated. Those of Dorset,
