Nobody from 110 years ago made perfectly accurate recordings.
Most of the early temperature recordings were of water temperature, because they measured it by literal buckets.
That information is still useful because we can make estimates about what the air temperature would have been like given all other available sources of information, and how air and water temperature relate to each other; but you can't just call it "the hottest temperature on record", let alone "the hottest temperature ever".

True, but people from 110 years ago had no political pressure to get "correct" recordings either.
