E. Hill, F.G.S., in illustration of his paper. 
A specimen of Megalichthys, exhibited by Prof. L. C. Miall, F.G.8., 
in illustration of his paper. 
Microscopic sections, exhibited by F. Rutley, Esq., F.G.S., in 
illustration of Dr. Koto’s paper. 
A globe with a great circle, which nearly corresponds to the prin- 
cipal gold-producing mines of the world, exhibited by Mr. J. Bad- 
deley. With reference to this last object the President stated that 
the exhibitor, who had been engaged for the last thirty years in 
gold-mining in various parts of the world, had marked upon a small 
globe a great circle of the earth, cutting the equator obliquely in 
long. 10° E. and 170° W., and with its northern and southern 
tropics in lat. 45°. This circle will be seen to correspond nearly in 
position to some of the pring al gold-producing mines of the world, 
in Australia, in several parts’ of North America (from California to 
Nova Scotia), and in Africa. He wished especially to call attention 
to the circumstance that gold-mines on this belt are worked to 
sreater depths than in Spain or other old gold-mining countries, and 
suggested that attention should be paid to the regions traversed by 
the circle in Africa, such as the head-waters of the Zambesi and 
Quango rivers.
