Noah Haynes Swayne,
Beaver v. Taylor (68 U.S. 637)…
“ The principal fact was the transmission of the receipts. The other facts so illustrate and characterize it, as to constitute the whole one transaction, and render the latter necessary to exhibit the former in its true light and give it its proper effect.It is, perhaps, not possible to lay down any general rule as to what is a part of the res gestae which will be decisive of the question in every case in which it may be presented by the ever-varying phases of human affairs. The judicial mind will always be compelled frequently to apply the general principle and deduce the proper conclusion. ”
