 From this it is evident, he adds, that, when they were executed,

 the open air *, the detaching of the figures contributes much to 

 the distinctness of the groups, and to the harmony of the gene-

On the Magnetic Influence of the Heat produced by the Solar 

 Rays^ S^c. By Mark Watt, Esq. Member of the Werne-

xjLS the curious and diversified phenomena disclosed by recent 

 investigations into the laws of magnetism, and the delicate im- 

 pressions of which they are susceptible, have become objects of 

 general interest ; perhaps a short statement of a few experi- 

 ments made on the magnetic needle last spring aftd summer, in 

 the Isle of Wight, may not be unacceptable. 



A magnetic needle of about three inches long was used, and

It is generally supposed, that when a magnetic bar is placed
