: f -.-w persons outside of ■ka ot the biological stnilents that liavo ;. i y i ea of what is meant by the tpression "'au ;:tom of matter." When the ïiiieroBcoye is npplied to the examiaation of living tissue, whether that tissue be of animal or vegetable life, it s soon observed that all living things sre made up of minute bodies called 'organisms." Experts in the various branches ot biological research will also teil you that no essential difference can be distinguished between thoBe cells which go to mako up the sum total of animal life and those which give the vegetable its existence. These life cells, although wondt! within themselves, are made up of minute partióles called "atorns, " which are eo small that they must ever remain invisible to the human eye. Soinecritical reader will say, "If this last remark be true, how can ft be proved that such infinitesimal particles as your so called 'atoms' exist?" To this query the reply would be that it is only when an untold number of these atoms unite themselves so as to form a single body, like the grains in a popcorn ball, that they become at all j ble and then only by the best appliances j that optical science has been able to I furnish. This being the case, it is not an exaggeration to say that every little piece of matter which we are able to see is built up of millions upon millions of these atoms which are so small that ao mind can comprehend their minuteness, even when taken in aggregations of thousands. There are, of course, many different kinds of atoms, such as atoms of carbon, hydrogen, oxygen, etc, eachof which is believed to have its own particular size and weight. Then, too, tbey probably diffei in shape as well ae size. According to the specialists in this line, they combine together by mutual attraction, which is in some cases called cohesión and in others chemical affinity, according as the atoms are of the different eleruents. This being th6 case it is easv to understand whv iads of these atoms of all sizes and shapes, fitted snugly one against the other, combine together in varying degrees of iutensity to baff3 up structures posseasing all the various degrees of 8tabilityand solidity. Someof the most wonderful theories ever advanced on the atomic theory are by Sir Williatn Thomson, the English scientist. In one of these articles he proves by tbree different tiainsof arguinents that an atom cannot be greater than the one one hundred and fifty millionth of an inch nor less than one-five billionth of an inch.
