It was proposed to raise the funds for the support of 

 the Institution by a subscription of fifty guineas from 

 each of the proprietors and founders, a contribution of 

 ten guineas from each subscriber for life and of two 

 guineas from annual subscribers, by donations and lega- 

 cies that might reasonably be expected, and by fees from 

 visitors and attendants on the lectures. 



The original subscribers, or proprietors, before being 

 called upon for payment, were to be secured against any 

 further demands for contributions, and from all legal 

 obligations for debts that might afterwards be incurred 

 by the managers, through the terms of a charter pro- 

 viding them that security. These proprietors were 

 not to be compelled to serve as managers or visitors 

 against their consent or inclinations. Half of the sums 

 subscribed by them was to be permanently invested in 

 the public funds, or in freehold property, that the 

 income might meet the expenses of the Institution.
