304 PROCEEDINGS OF THE ACADEMY OF 



The basin of the Essequibo is about 900 miles long N. and S., and 600 E. 

 and W. It is the true auriferous field of Venezuela. 



Fragmentary knowledge comes in from all known portions of it, showing all 

 its mountains to be gold-bearing. 



In the valley of the Moeupio, a small and insignificant tributary of the 

 Yuruary, the greatest amount of exploration has been done. Here has been 

 developed two systems of veins ; one running N. E. and S. W., corresponding 

 with the strike of elevation ; the other E. and W., corresponding with the 

 strike of talcose rock. 



On the method of the formation of gold in the veins, the following observa- 

 tions have been made : 



First. Showing that gold must have been placed in the veins at the same 

 time with the quartz matrix, and that these were deposited pan joassw on both 

 walls of the vein. 



Secimd. Observations show that gold has been redisposed on fissure walls of 

 the quartz. 



Third. Observations show that gold has been mechanically mixed with the 

 sulpburet of iron, and that these depositions were made simultaneously with 

 the quartz. 



The best known portion of the new gold fields of Yuayana are situated in 

 the canton of Yurnary (formerly a portion of the canton of Upatee), in lat. 

 7° 20^ N., find long. 65° W. from Greenwich ; about 100 miles south from the 

 island of Piacoa, in the Orinoco river, and 200 miles south-east from Bolivar, 

 over the great plains of Venezuela.

 The President, Dr. Hays, in the Chair. 

 Thirty-two members present. 



The chairman of the Curators announced that B. Waterhouse 

 Hawkins, F. G. S., had presented to the Academy a restored skele- 

 ton of the Hadrosaurus Foulkii, on which the following resolutions 

 were offered and adopted : 



Resolved, That the Academy entertain a deep sense of obligation to Mr. Haw- 

 kins for his valuable donation of a restored skeleton of Hadrosaurus Foulkii, — 

 a gift which will constitute an especial attraction and a prominent object of 

 interest in our museum. 



Resolved, That the profound palffontological knowledge, artistic skill and 

 patient industry displayed by Mr. Hawkins in reconstructing from some frag- 

 mentary remains this huge creature of a former geological period, has gained 

 for him our respect and admiration, while his invariable courtesy and freedom 

 in imparting knowledge has secured our highest regards. 



Resolved, That the Academy full}' appreciate the great value of the efforts he 

 is making to ])opularize science ; efforts, the importance of which cannot be 

 too highly estimated. They will tend to benefit the community by expanding 

 the minds of the masses, and by furnishing to them higher and more ennobling 

 subjects for thought than can be afforded by the common ])ursuits of every-day 

 life. He will also advance science by increasing the numi)er of those who can 

 appreciate the labors of men of science, sympathize in their labors, and secure 

 for them objects of interest which would be thrown aside or destroyed by the 

 ignorant. 



Resolved, That the Academy tender to Mr. Hawkins its best wishes for his 

 health, happiness and prosperity. 



The following gentlemen were elected members : Wm. M. Dar-
