bullet แปลว่า

"—Chicago boasts of a citizen of fine discrimination and delicacy, who, riding in the suburbs with his best girl, passed a stable in the door of which stood a couple of calves. "See," said the young lady, "those two cute little cowlets." "Those are not cowlets, Araminta; they are bullets.""

"“I am not sure a compilation of odds and ends should be called a ‘book.’ Perhaps ‘booklet’ would be the better designation. My daughter, when quite young, once spoke of a heifer calf she saw grazing on the rim of the road as a ‘cowlet.’ In reality, the wayside animal was a ‘bullet.’ Though this book, or booklet, isn’t even calf-bound, the analogy should have been close enough to make me wary of jumping to a conclusion. However, it is too late now."

"YES — imagine, if you can, that all human beings are cows and or bulls for just one day (I just can’t stand the thoughts of being a cow for more than one day). SO — lets^([sic]) take the cow and bull side of the question first. REMEMBER — you are a cow or bull. Mrs. Cow has been home all day busy getting the cotton seed meal and hulls ready for dinner, tending to the little cowlets and bullets and baking a bale of hay."
