Edward Douglass White, American Express Company v. Maynard…
“ A stamp duty is embraced within the purview of those taxes which are denominated indirect, and one of the natural characteristics of which is, although it may not be essential, that they are susceptible of being shifted from the person upon whom in the first instance the duty of payment is laid. We are thus invoked by construction to add to the statute a provision forbidding all attempts to shift the burden of the stamp tax when the nature of the indirect taxation which the statute creates suggests a contrary inference. ”
