section warranty part the three cause be when the condition be such that if  the elder son alien c that his estate shall cease or be void c then after such  alienation c may the donor enter by force of such condition as it seem and so  the donor or his heir in such case ought soon to have the land then the second  son that have not any right before such alienation and so it seem that such  remainder in the case aforesaid be void here it be to be observe that part of  the condition that prohibit the alienation make by tenant in tail be good in  law with such distinction as have be before say in the chapter of condition  and the consequent of the condition videlicet that the land shall remain to  another c be void in law and by the opinion of Littleton the donor may  re-enter for the condition break for utile per inutile non to make faulty  which be in case of a condition for the defeat of a estate be worthy of  observation and it be to be note that after the death of the donor the  condition descend to the old son and consequent his alienation do extinguish  the same for ever wherein the weakness of this invention appear and therefore  Littleton here say that it seem that the donor may re-enter and speak nothing  of his heir a man have issue two son and make a gift in tail to the old the  remainder in fee to the puisne upon condition that the old shall not make any  discontinuance with warranty to bar he in the remainder and if he do that then  the puisne son and his heir shall re-enter the old make a feoff in fee with  warranty the father die the old son die without issue the puisne may enter but  if the discontinuance have be after the death of the father the puisne can not  have enter in this case four point be to be observe first as Littleton here  say the entry for the breach of the condition be give to the father and not to  the puisne son second that by the death of the father the condition descend to  the elder son and be but suspend and be revive by the death of the old son  without issue and descend to the young son three that the feoff make in the  life of the father can give away a condition that be collateral as it may do a  right fourthly that a warranty can bind a title of entry for a condition break  as have be say but if the discontinuance have be make after the death of the  father it have extinct the condition which case be put to open the reason of  our author opinion in these last three section our author have teach we a  excellent point of learning that when any innovation or new invention start up  to try it with the rule of the commonlaw as our author here have do for these  be true touchstone to sever the pure gold from the dross and sophistication of  novelty and new invention and by this example you may perceive that the rule  of the old commonlaw be sound as our author have do apply to such novelty it  do utter crushthemandbringthemtonothing and common a new invention do offend  against many rule and reason as here it appear of the commonlaw and the  ancient judge and sage of the law have ever as it appear in our book suppress  innovation and novelty in the beginning as soon as they have offer to creep up  lest the quiet of the commonlaw may be disturb and so have act of parliament  do the like whereof by the authority quote in the margin you may in stead of  many other upon this occasion take a little taste but our excellent author in  all his three book have say nothing but ex old times  prudence over et more
