Ii appears from this comparison, that none of the situa- 

 tions here enumerated, North of Lisbon, except Penzance, 

 has any material advantage over London in the mildness of 

 its winter. The best part? of Devonshire seem to be about 

 a degree and a half warmer ; Torquay however may perhaps 

 be a little milder than this ; the account, which was kept 

 at Ilfracombe, must have been taken from a thermometer 

 in a confined or a sunny situation. But Penzance may be 

 fairly considered as having a temperature 4|° higher than 

 London in the coldest months; nor is the journal here 

 employed the only one, which allots such a superiority to 

 the climate of this extremity of our island. It is remark- 

 able, that the temperature of the three coldest months is the. 

 same at Paris as at Edinburgh, being, in both these cities, 

 about three degrees lower than in London. There are pro- 

 bably particular spots on the coast of Hampshire or Sussex, 

 which, from their sheltered situation, must be considerably 

 less subject to the effect of the northern and eastern winds, 

 than most other parts of the island ; and Hastings, or its 

 neighbourhood, may perhaps be reckoned among the most 

 eligible of these ; but the further we go up the channel, the 

 more remote we beconie from the mild gales of the Atlantic, 

 while the prevalent south-westerly winds, in passing over 

 a considerable part of the continent, must have lost much 

 of their warmih. It is scarcely necessary to observe, that 

 both Malta and Madeira present, numerically, a mean tem- 

 perature for the winter months, as favourable for an.invalid 

 as can possibly be desired. 



Equability of temperature is a second quality, of no small 

 importance, as tending to diminish the chance of incurring, 

 or aggravating, pulmonary diseases, by repeatedly taking 

 cold. When, indeed, the temperature is much below 60°, 

 the most material changes «re those which occur upoa 

 going frcmi the houee into the open air; so that a cold cli- 

 mate becomes, in some detjree, of necessity a changeable 

 one also. The recularily ot this change, and the power of 

 avoiding its eR'ecU by additional clothing, as well as of 

 obviating ihein in some measure by exercise, contribute
