or office may not be changed1 any more than a proper name, nevertheless he may  err as to that, as where2 the name is right but an error is made as to the dignity or  office; the writ is good. If an error is made in the name but the dignity or office is  correct, the writ is good. Sometimes the proper name is not expressed, and then the  name of the dignity or office is enough, if there is no error as to that, and the writ is  good against their successors, [that is], in a civil action where no penalty follows. If  it is a penal action ex delicto it also extends to successors where no proper name is  used, but not as to the penalty, only as to restitution, if he can restore.3 If the predecessor's  proper name was used, it would be otherwise4 Office and dignity are almost  equivalent terms, that is,5 every dignity is a kind of office, but not every office a  dignity. There may be an office without a dignity, as the office of sheriff or coroner.6
Of error as to the thing.
 Error sometimes is made as to the thing itself, as where one calls a thing a vineyard  where he ought to call it a church, or a lance instead of a vestment.7 For the names of  things are immutable, the names of men changeable.8 There may be error as to the  quality and quantity. Also as to the price, and in number, weight and measure.  And in kind and colour. There may be error as to the thing with respect to its place,  as where one says it is in one place when it is in another. But error of this kind  ought not to be prejudicial when what the demandant had in mind may be drawn  from the circumstances, [The same could be said of the division between fields,] as  where the view is sought, for it does not matter whether a particular thing is done or  something which amounts to it.
Of error as to the reason for an action.
 Error also is made with respect to the reason for an action, as where one in impetrating  causes it to be understood that he possesses rightfully what he possesses wrongfully,  or what he never possessed. Then we must see whether the reason is accidental  to the action, if so, it does not hinder it. If it is a condition of the action, it destroys it  completely.
Of error as to the place.
 There may be error as to the place, as9 where the disseisee impetrates to the sheriff  in whose county the tenement is not situated, or says the tenement is in one vill  when it is in another, as will be explained more fully below.10[There are many  exceptions against the writ dealt with below [in the portion on] the proprietary action,  some of which are applicable here and some not, just as some exceptions against  the writ in a possessory action, dealt with here, are not applicable there. For that  reason all exceptions against
