saw written the signatures appended thereto, and that, according to the information and belief of the affiant, each of said signatures is genuine, and the signature of a qualified elector of the county (or particular sub-division thereof in which such signers are hereby required to reside). Within ten days from the filing of such petition, the Registrar of Voters shall, from the records of registration, determine whether or not said petition is signed by the requisite number of qualified voters, and he shall attach to said petition his certificate showing such determination. If such certificate shows the petition to be insufficient, it may be supplemented within ten days from the date of the certificate by the filing of additional papers, duplicates of the original petition except as to the names signed. The Registrar of Voters shall, within ten days after such additional papers are filed, ascertain from the records of registration, and certify whether or not the names to such petition, including such additional papers, are still insufficient, and if insufficient, no action shall be taken thereon; but the petition shall remain on file as a public record. The failure to secure sufficient names shall not prejudice the filing later of an entirely new petition to the same effect.

In case the Registrar of Voters is the officer sought to be recalled, the duties in this Article provided to be performed by him shall be performed by the County Clerk.

If a vacancy occur in said office after a recall petition is filed, and the office is elective, the election shall nevertheless proceed as in this section provided.

Nominations for any elective office under such recall election shall be made by petition in the manner prescribed by section 1188 of the Political Code. Upon the sample ballot there shall be printed, in not more than two hundred words, the grounds set forth in the recall petition for demanding the recall of the officer, and upon the same ballot in not more than two hundred words, the officer may justify himself. There shall be printed on the recall ballot, as to every officer whose recall is to be voted on, the following
