and also in fig. 6. A mixture of hydrogen and chlorine in 

 equal parts is represented in fig. 2, the chlorine C having 

 a dense stratum of electric atoms, and H only a few of 

 these ; the circles denote limits of the spheres of repulsion 

 which may be more or less ; the absolute force of C is 36 

 times greater than that of H, but probably its sphere of 

 repulsion is less ; the atmospherule of C will be more dense, 

 but the two will occupy equal spaces in the gas. While 

 the gas is perfectly still, and not acted on from external 

 causes, the mixture will continue a long time ; but, the 

 equilibrium of the electric atoms not being a stable one, 

 when caloric, or light, &c., has access, the effect will be to 

 bring the electric atoms between C and H, (prop. 1,) and 

 the accumulation of part of them there will increase the 

 effect on the rest ; these electric atoms will then form an 

 intermediate link, and hold C and H under one common 

 atmospherule, forming muriatic acid as in fig. 3, where the 

 centres C H' are at the same distance as before. I believe 

 no other theory can give any rational account of these 

 phenomena. By supposing variations in the absolute force 

 and sphere of repulsion, fig. 3 may represent any of the 

 first five compounds in the table. 



Etherine is shewn in fig. 4; there are two atoms of 

 carbon with small, and four of hydrogen with large spheres 

 of repulsion, the six centres being within the sphere of 

 repulsion of the hydrogen, the whole occupies but one 

 volume (prop. 3. cors). This is isomeric with olefiant gas, 

 whose atom would be represented by one of carbon and 

 two of hydrogen. 



Fig. 5 represents all the compounds in the table, from 

 number 26 to 33 inclusive, by supposing only an alteration 

 in the absolute force and sphere of repulsion. Fig. 6 

 represents ether, it is two of fig. 4, connected by fig. 5. 

 The connecting atom in fig. 5, and the connecting group in 

 fig. 6, while they retain the whole under one atmospherule, 

 and bind them together, do not (prop. 3. cors.) alter the 

 distance between the atoms or groups which they connect. 

 In the original communication a figure was given for every 

 compound in the table.
