Between “Tom” and “Jack” there is a vast difference. “Jack” is the sharp, shrewd, active fellow, but Tom the honest dullard. Counterfeits are “Jack,” but Toms are simply bulky examples of the ordinary sort, as Tomtoes. No one would think of calling the thick-headed, ponderous male cat a Jack, nor the pert, dexterous, thieving daw a “Tom.” The former is instinctively called a Tom-cat, and the latter a Jack-daw. The subject of “Jack” has been already set forth. (See Jack. ) Let us now see how Tom is used:
Tom o' Bedlam (q.v.).
A mendicant who levies charity on the plea of insanity. Tom-cat
. The male cat.
Tom Drum's entertainment.
A very clumsy sort of horse-play. Tom Farthing.
