Joseph Story,
Douglass v. Reynolds Byrne Company…
“ The fourth instruction insists, that a demand of payment should have been made of Haring, and in case of non-payment by him, that notice of such demand and non-payment should have been given, in a reasonable time, to the defendants, otherwise, the defendants would be discharged from their guarantee. We are of opinion, that this instruction ought to have been given. By the very terms of this guarantee, as well as by the general principles of law, the guarantors are only collaterally liable, upon the failure of the principal debtor to pay the debt. ”
