The image on your other question looks to me like Police Precinct 6, Tract 19. A name would help to narrow it down.
This query on FamilySearch has about 8000 records matching against that precinct/tract. Searching on Rittenhouse Street does not provide any results.
Ok, I think this your matching image. How I found it:
Use the query above.
Click through to an arbitrary image.
Look at the "breadcrumbs" header above the image:
United States Census, 1940 >>
District of Columbia >>
District of Columbia >>
Police Precinct 9, District of Columbia, Tract 23
Click on the Police Precinct link, navigate to Precinct 6, Tract 19
Notice that the images are in order according to "Population Schedule", jump forward 39 images to the right page for Schedule 263 as seen in the header you posted in the other question.
It's also worth noting that searching for, say, "Raymond Mitchell" in Precinct 6, Tract 19 would have gotten you immediately to the record in question.
