shore. Observations on the springs in the town gave no correct 

 results. Bforners spring, on the north side of the town, was, on the 

 23d June, 39-74°; on the 20th August, 42-8°. 



Ulsaters mountain spring was, on the 23d June, 38 - 6G°; on the 

 19th August, 43-16°. 



I found at last a better spring on the height in the parish of Hcg, 

 at a place called Tannasabod(ir s on the left side of the way behind 

 the forge of Stf&mbacka. it gave, on the 20th Ai gust, 40-28°; 

 not much less than the little hill of Skog. 



The spring Skallnaess, not far from JMahlsta, and in the division 

 of Fronlandsby, was, on the 1 9th August, 40 , 82°. 



Scabiosa suecisa grows here in abundance ; chiefly, however, in 

 the interior of the country, and seldom on the sea shore, or the 

 borders of rivers. 



DalUmync spring, half a Swedish mile beyond Maldsta, gave, 

 on the 24th June, 40-46°; on the 19th August, 41-9°. 



In the northern part of Helsingeland, in the parish of Gnarf>, a

In this province there are several perpetual springs. That of the 

 mineral water called SolomskHlla, in the parish of Salt7ta, was, on 

 the 27th June, 39-02°; on the 16th August, 39-92°. 



Dr. Zederstrom found its temperature, on the 12th July, 1S03, 

 39 - 2°. An observation was likewise made on a good spring at 

 Hasans Stvedjan, south-west from that place, in the same parish. 

 It was, on the 17th August, 39-2°. 



We may therefore consider this as the true mean temperature of 

 the earth for this place. 



One quarter of a Swedish mile north-west from Sundswall, at 

 Slorti, in a morass, a spring gave, on the 18th August, 39-56°. 



Another, situated not far from the first, on the 26th June, 

 39-38°; and on the 18th August, 41°. 



Hcople here are of opinion that a subterraneous stream flows 

 hither from the north. It is certain that in these hilly districts the 

 water retains its low temperature, though the ground is perhaps too 

 much exposed to the influence of the sun's rays. That such a 

 situation must have a considerable influence on the temperature of 

 sprint's i* evident from the strong spring of Sjobergsk'dUa, at Sundt- 

 wally which lies on a fine southern declivity, and on the 2Cth June 

 WW of the temperature J 1'72° ; and on the 18th August, <12-9S°. 

 In such a situation the high temperature <>f the earth remains long 

 unaltered. Hugskalia, at the church of Thnmtru, w; , on the 

 27th June, 4I-S6°i and on the L6th August, 41-72°. These con- 

 stitute exceptions which must be neglected in a general view, as
