From this comparison of the tables we may draw the following conclusions :— 1. A space which will contain 1 atom of hydrogen in the gaseous state is capable of holding the following numbers of atoms of the follow- ing compounds according as they are or are not in the aeriform state; water 1 and 1234 ; carbonic acid 1 and 419; sulphurous acid 1 and 500; sulphuric acid 1 and 547; arsenious acid 2 and 420; oxide of chlorine 4 and 247 ; hyponitric acid 4 and 350; sal-ammoniac + and 312; dichlo- ride of mercury 3 and 325; protochloride of mercury 1 and 439 ; ter- chloride of phosphorus 3 and 117 ; chloro-sulphurie acid 1 and 749; di- bromide of mercury 3 and 289; proto-bromide of mercury 1 and 365 ; di-iodide of mercury % and 258 ; prot-iodide of mercury 1 and 303; sulphuretted hydrogen 1 and 588; cinnabar 2 and 762 ; bisulphuret of carbon 1 and 504. The highest degree of condensation that takes place in the passage of a body from the gaseous to the liquid or solid state amounts therefore to 1234 times (water) ; the lowest to 210 (arsenious acid), These numbers also show the incorrectness of the law enun-~ ciated by Persoz (page 57). Since 1 litre of vapour of water at 0° weighs 0°8003 grammes and 1 litre of water 1000 gr., Persoz, divides the weight in grammes of any compound in the gaseous state by 0°8003 in order to get the sp. gr. of the same compound in the liquid or solid
