Excepting the natural growth of the jaws, in common with other parts, no changes occur which will assist the examiner in judging the age of the young pig until the age oi five months is reached. At this time there are evident signs of the cutting of the pre-molars ; and the fourth molar, which is the first per- manent tooth, is seen behind the temp
