EXPLANATION. 



Dottcil lines Bbow the uinter 



temperature a.s influeneed 

 by the Gulf Stream. 

 (Isotherms for January : 37*, 39\ 40°, 

 41% 42°, 43°, 44° Fahr.) 



Fine continuous lines show the 



jiummcr temperature, as io- 

 tluenccd by the otm-hcat. 

 (Isotherms for July : 59', CO", 61", 02", 

 03°, &1°.) The 44° ami 01° iBotlierms 

 have been accidently omitted. A line 

 drawn through the Lizard and St. Ives 

 Bay would represent the former, ami a 

 curve from 04° to tlie Land's End would 

 Bhow the place of the latter.

north-east, and, favoured by the Solway Firth, are seen to ' 

 cover a large portion of Cumberland. 



On the eastern coast 37° isotherm hugs the coastline 

 verj' closely ; still it is seen to be deflected to south-west , 

 at the broad mouths of the Tecs and the Ilumbcr, and to a , 

 still greater extent around the Wash and the mouth of the 

 Thames. We need not here repeat the names of the i 

 health-resorts which lie between or on tlicse isotherms ; 

 they are sufficiently indicated on tlie map by figures which 

 correspond with the names in the list of seaside towns and 

 health-resorts in England and Wales given above. ! 



Having seen how the Gulf Stream heat tempers the | 

 winters of our coast.s, we will now proceed to examine the 

 July isotherms, represent<'d by fine coiithinouH Unci. These i 

 lines may be said to cross the January isotherms almost at I 

 right angles, and to follow roughly the parallels of latitude. | 

 They also are characterised by curves which have a ' 

 northerly direction as regards their a.xes. Whilst, how- 

 ever, the winter curves showed that the axis of greatest 

 heat is carried in a North-Easterly direction over the sea ; 

 during January, the summer curves equally well show that : 



the axis of greatest heat extends from South to North over 

 layiJ, and that the isothermal curves reach the highest 

 points towards the North along the central a.vis of the 

 country, whilst on each side of the coast the isotherms are 

 depressed, indicating the cooling eflect of the sea on the 

 sun heat of July. 



Again, we may contrast the ell'ects of the sea on the air 

 temperature during winter and summer. We have just 

 seen that the Bristol Channel and the Thames cmboucfiuin 

 allowed tlie sea warmth to penetrate the surroBnding 

 country in the winter ; if we now look at the curves in 

 G3° July isotherm around these two seA inlets, we shall at 

 once observe how remarkably the winter heating and 

 sunnner cooling depends upon the sea. 



In our next, we shall group the health resorts in ac- 

 cordance with the lieadiiig at the beginning of our last 

 paper.
