10. The directress of the school, conferring with the superior and commission of supervision, created by article 26, is authorized to dismiss any girl who deserves it, informing the member of the ayuntamiento who is charged with the admission. Cases for expulsion shall consist of: a contagious disease, special laziness, and lack of application, stubbornness, and serious lack of respect toward the teachers, bad deportment, and morals harmful to the other scholars. 11. In case of a contagious disease, a medical examination at the wish and expense of the parents shall precede the resolution to dismiss the girl. For the cause of lack of application or stubbornness, the scholar who incurs these faults shall not be dismissed except after the attempt by reasonable means to correct her, and warnings, once, twice, and thrice, to the parents of the party interested. But when the deportment and irregular morals of any pupil concern the innocence of the other girls, she shall be dismissed without delay, with the advisable reservation. Nevertheless, both in such case and in the preceding, all due consideration shall be observed toward the girl and her parents. 12. Girls who, without any legitimate cause approved by the directress of the school, shall be absent from class thirty consecutive or interspersed times, in the same year, shall not receive a reward in their examinations. Sickness, necessary absence from this capital, and the bad weather which makes the streets impassable shall be a sufficient excuse. 13. For the admission of boarders and half-boarders, the resolutions drawn up in special regulations shall be observed. Until such regulations are published the directress of the school may admit half-boarders exactly in the manner in which pupils are received, namely, as arranged by articles 7 and 8 of this same chapter.
