simple elementary forms of forces or substances, as of the axial 
forces of the molecules, elasticity, cohesion, é&c.? By a perfect 
and essential knowledge of these, the philosopher must construct 
his framework of the material universe, as by his similar knowl- 
edge of the organic forces and forms of forces, he may hope at 
some future time to attain an idea of life. 
- With these distinctions it is perhaps possible to separate the 
notion of an hypothesis, or of the hypothetical method, from the

instantly a ‘caloric’ is invented, a thing without shape, use, prop- 
erty, energy, or law in itself—a mere alchemistical ghost. Again, 
PEOUn, acquire a certain position, when left free, 1m regard to the 
earth’s axis, when at once starts up another spectre in the shape 
‘of a magnetic fluid, divided into its particles, but without any 
inable shape, properties, or qualities, a mere burthen to 
sht, and creating a thousand difficulties without solving one.
