UNITED STATES U. WYNN. 891 �used, if they We coiuraon-lawterms, to the common law, yet they could not enlarge the punishment beyond -what the federal sta tutes prescribe. Similar offences may have been capital under the British law. Yet congress may have denounced therefor imprisonment merely for a limited term, or merely a fine. How, then, is the offence to be designated, — according to the federal statutes, which must alone govern, or aocording to the common law, which is no part of the federal system ? �Without pursuing further this abatract line of thought, which leads to a reductio ad absurdum, it may be well to state Buocinotly the views of this conrt.
