Henry Billings Brown,
Fire Insurance Association v. Wickham…
“ There is no doubt that, when a receipt also embodies a contract, the rule applicable to contracts obtains, and parol evidence is inadmissible to vary or contradict it. But the only clause in these receipts which can possibly be claimed to partake of the nature of a contract is that providing for a concellation and surrender of the policy. There was a similar provision indorsed on the policies. These, however, were inserted in pursuance of a clause in the policy to the effect that the insurance might be terminated at any time, at the option of the company, upon giving notice to the insured ”
