 Feet apart, and less than forty feet in depth, or there are cross walls which in leisect the wall, not more than forty rect distant or between the same, or piers or buttresSes built into the walls, the inferior walls may be reduced in thickness In just proportion to the number of cross walls, piers or buttresses, and their nearness to each ot1erj provided, however, that this feet in height, and that no such wall shall be less than twelve inches thick at the top, and gradually Increased in thickness by set o1S to the bottom; and the, Inspector Of Buildings Is hereby authorized and empow- cred to decide (eXcept where herein other

 Iron or steel girders, shall not be less than
 twelve Inches thick for fifty feet of the up
 permost height thereof or to the nearest n. p
 building so constructed and every lower
 section of fifty feet or to the nearest tier of beams to such vertical measurement, or part thereof, shall have thickness of four inches more than is required for the section
 next above 1t, down to the tier of beams nearest to the curb level; and thence down. ward the thickness of walls shall increase
 In the ratio prescribed in section twenty one of this title for the thickness of found
 ation walls.
 The height Of all stories for all given
 thtcknesses of walls both in this section
 and section twenty-three must not exceed eleven feet in the clear for the basement,
 seventeen feet in the clear for the first
 story, fourteen feet ill the clear for the sec

 all stories above the second. If any story
 exceed these heights respectively the walls
 of such story and the walls of all stories
 below the same shall be Increased four
 inches in thickness additional to the thick neSSeS already mentioned.
 Sec. 20, In all walls the same amount of materials may be used in piers or buttresses.
 Curtain walls may be made four inches less
 in thickness than is specified respectively
 for walls of dwellings, and buildings other
 than dwellings. If any horizontal section
 through any part of any bearing wall in
 any building shows more than twenty-five
 per centum area of tiues and openings, the said wall shall be increased four inches in
 thickness for every ten per ceutum or frac- ton thereof, or t1ue or opening area in ey-
 cess of twenty five per centum All piers
 shall be built of stone or good, hard well
 burnt brick laid in cement mortar. Every
 pier built of brick, containing less than nine superficial feet at the base, supporting any beam, girder, arch or column on which a wall rests, or lintel spanning an opening over ten feet and supporting q wall, shall at intervals of not over thirty inches apart
 in height have built into It n bond stone not

 brick work, but in no case shall said walls
 or piers be less than three-quarters of the
 brick walls every sixth course shall be n
 heading course, except where walls are faced with brick in running bond, in which
 latter case every sixth course shall be bond ed into the backing by cutting the course of
 the face brick aud putting in diagonal lead CTS behind the sdme, or by splitting face
 brick in half and backing the san with q
 continuous row of headers. All s one used for the facing of any building, sd known as ashlar, shall not be less than .our inches
 thick stone ashlar shall be anchored to
 the backing and the backing shall be of such thickness as to make the walls (inde- upDIpDt nj tho aSblot') apufprn n tho fhipE

 of a wall shall be backed up with the same | thickness of brick work as stone ashlar
 Walls heretofore built for or used as party walls, whose thickness at the time of their erection was in accordance with the require meuts of the then existing laws, but which are not in accordance with the requirements
 of this title, may be used if in good condi- ton for the ordinary uses of party walls. provided the height of the same be not in creased In case 1t Is desired to increase the height of existing party or independent walls, which walls are less in thickness than
 required under this title, the same shall be
 done by lining of brick work to form |, combined thickness with the old wall of not less than four inches more than the thick
 ness required for new wall corresponding | with the total height of the wall when so increased in height. The snd lining shall be supported on proper foundations and carried up to such height as the Inspector of Buildings may require. No lining shall be less than eight inches in thickness, and
 all lining shall be laid up in cement mortar and thoroughly anchored to the old brick walls with suitable wrought iron anchors placed two feet apart and properly fastened or driven to the old walls In rows alternat- i ing vertically and horizontally with each | other, the old walls being first cleaned of | plaster or other coatlngs where any lining | is to be built against the same.
