vy! PROPOSED: NEW LAWS of MOTION. 
PANHE. Author of the NEW PHILO- 
4 sory is printing eight supple- 
mentary. pages on the mechanical 
egauses.of Gazcous Elasticity, of Con- 
dueting Power, and of the Phenomena 
of Magnetism; and has also introduced 
anew series: of Principles or Laws of 
MOTION. The latter are submitted to 
theopublic: at large, and a comparison 
mvited ‘with the Laws published by 
Descartes, and adopted by Newton. 
°'The following are submitted as 
Laws of Morion more consonant with 
reason and nature than the proposi- 
tiens hitherto so called. 
1, Matter meyer originates its own 
motion. 
2.\Aikmotion acquired by one body 
is «thes (result of. motion transilerred 
fromsomelother moving body or bodies.

#ransferred to ‘some other body er 
bodies.

6. Re-action is the receiving of mo- 
tion bysthe patient from the agent. 
~% Actiom and re-action are there- 
fore convertible terms, and in fact ne- 
cessarily equal. 
§. Every body continues in motion 
till itchas) parted with its motion to 
other bodies: 
9. Parting: with: motion is effected 
by impinging, or by contact. 
10. Resistance sis the parting: with 
motion to the atoms of a fluid or’solid, 
through which the moving body passes, 
and is proportional to the density and 
the cohesion or viscidity of the patient. 
11. Friction is the parting with mo- 
tion by continuous :contact,; and is 
proportioned: to; the number: of ‘atoms 
of the agent which are opposed to the 
atoms of the patient. = 
12. Quantity of motion, or momen- 
tum, is the velocity multiplied bythe 
number of atoms moved. ae 
13. Impulse of motion is the transfer 
of motion, either by contact, ior by, the 
intervention of aJever, ; 
14. All motion: received iby impulse 
is in the direction of the impulse: «

tween a body moving, and one .moved,, is 
called a lever; and levers, may, consist 
either of fixed, or of fluid, or of gazeous 
matter. ; 
culous, But it does not follow that, be- 
cause the author does not affect to deter- 
mine the origin of motion, that therefore 
certain known motions are not the) cause 
of material phenomena. generally, more 
than that as it is not pretended by sober 
philosophers, to determine the, origin; of 
things, that therefore nothing exists. _Phi- 
losophy treats only of proximate causes. 
It may. ascend from cause to cause, but 
its investigations aré not to be impeached 
because it does not ascend from great cause 
to greater, or from great motions to greater, 
till it comes into contact with, the pri- 
mary source of all causes and all existence. 
‘The observations on, atomic Phenomena, 
on atomic motion, and on the formation of 
various bodies, leads howeyer to a -Ques- 
tion not unworthy of consideration, but 
which it is not affected to determine —
