it, but the deflected stream would heighten the temperature of the 

 waters of lower latitudes, and cause an increased evaporation ; conse- 

 quently there would be an increased condensation upon northern 

 mountains and Polar shores, and an increased reflection of the succeed- 

 ing summer's sun. It was rather a curious fact that less American 

 driftwood had been brought to the northern shores of Iceland during 

 late years, and an increased amount had been cast upon its southern 

 coast. This little fact of course proved nothing in itself; but when 

 we saw northern glaciers advancing to the extent they had done one 

 naturally asked the reason. Astronomical causes must be put on one 

 side, for the glacial advance was too rapid to admit of that solution. 

 But if northern glaciers continued to advance it would be a matter of 

 some interest if we could ascertain whether those mysterious forces 

 wliich gave birth to the earthquake and the volcano had wrought any 

 alteration in the flow of that guardian angel of the north— the Gulf 

 Stream. 



The Ex-President (Mr. Haselwood) proposed a vote of thanks to 

 Mr. Watts for his extremely interesting and instructive lecture. As 

 far as he understood them, his arguments seemed to point to the 

 probability of another glacial period, though at a future so remote as 

 hardly to be calculable. 



Mr. E. Moore, from what he had gathered from Capt. Burton's 

 book, looked upon the difiiculties in the way of the transport of 

 sulphur as almost insuperable. Perhaps Mr. Watts would be kind 

 enough to tell them what means of transport it was proposed to adopt, 

 so as to make sulphur an article of commerce. 



Mr. W. Henty supposed the fact of there now being a deficiency 

 of warmth in Iceland for the growth of corn was due to the increase 

 of glaciers. 



Mr. T. W. WONFOR wished to know whether thunderstorms 

 were as frequent in the northern parts of the island as in the southern ? 

 Mr Watts's remarks had cleared up some points in his mind as to the 

 presence of aqueous particles in volcanic products ; but he was 

 surprised to hear that such enormous bodies of water were thrown out 

 of the volcanoes. He should feel obliged if Mr. Watts would give 

 some further explanation as to the enormous showers of ash which
