The annotation, d a°C/b°C, indicates density of solution at temperature a divided by density of pure water at temperature b known as specific gravity. When temperature b is 4 °C, density of water is 0.999972 g/mL.
Methanol and its vapours are flammable. Moderately toxic for small animals – Highly toxic to large animals and humans (in high concentrations) – May be fatal/lethal or cause blindness and damage to the liver, kidneys, and heart if swallowed – Toxicity effects from repeated over exposure have an accumulative effect on the central nervous system, especially the optic nerve – Symptoms may ...
On inquiring about the temperature at which paper would catch fire, Bradbury had been told that 451 °F (233 °C) was the autoignition temperature of paper. [ 30 ] [ 31 ] In various studies, scientists have placed the autoignition temperature at a range of temperatures between 424 and 475 °F (218 and 246 °C), depending on the type of paper.
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.

The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

All are technically right in a way ! My experiments conclude , Paper can ignite in 15 minutes at 451 Fahrenheit or 233 Celsius and 1.5 minutes at 600 Fahrenheit or 315 Celsius , 30 seconds at 752 Fahrenheit or 400 Celsius and instantly at 900 Fahrenheit or 482 Celsius . Printer paper was used . Hope this puts it to bed !
