It's by Sir John Betjeman (pronounced bechaman, if memory serves), and is an elegy/obituary notice for Walter Ramsden. What's "I.M.", an Interior Minister? Not sure. Apparently Wally read the obituary notices every day. Is "obsequations" a word? A new one for me, if so. Betjeman mentions things about Ramsden, much the way one would recall such attributes speaking at a funeral.
The form is complicated, apparently Sir John's own invention? Some take-off on sapphics, perhaps. That is, long lines, with a short trimeter, dimeter or monometer (in this case) finish, probably merely for emphasis. Usually one sees them as quatrains, with three long ones and one shorty. Here, the long lines appear to be of eight iambic & anapestic feet and (mostly) an iambic single foot for the punch. Rhymes are abab, etc. Endings mix both masculine and feminine for the long lines, all single-syllable masculine on the shorts.
For extra credit, look up 'amphimacer', and explain how that is the foot used for such a line as "Kitchin din" or "Cups and plates". Could these be anapests instead of amphimacers? Make your own case.
