Sec. 1, Par. (g). The depth of a lot would be measured, where pos- 

 sible, parallel with the sides of the lot, but if they were not parallel it would 

 be measured in the direction of the bisectrix of the angle between them. 

 Where there would be more than one bisectrix the resultant bisectrix would 

 be used. 



Sec. 1, Par. (h). This differs from the definition in the Tenement 

 House Law. There the rear yard is between the extreme rear line of the 

 building and the rear of the lot. Here it would be between any rear line 

 of the building and the corresponding rear line of the lot behind it. How- 

 ever, it has been the custom of the Tenement House Commissioner to 

 interpret that law in the manner here suggested.

Sec. 1, Par. (i). This definition of the depth of a rear yard applies 

 only to determining the depth of a rear yard as a percentage of the depth 

 of the lot. It does not relate to the " least dimension " of a yard required 

 at any given height.
