pharmacy on Main street. 1ne models were made and arranged by chemistry students at the Wa tertown high school under the de rection of Patrick F'ontane, chemis- try instructor. The display IS based on "The Structure of Matter" and exemplifies a slightly more et- fective method of teaching chemis- try to the students of today.
 Tn explanation a student of the high school has written a theme on the subject, simplified yer sion of which is as follows:
 scientists believe that the moun- talns, oceans, the air and even the s.ars are composed of one or more of the 92 elements. These elements cannot be broken down into any simpler substance, hut every known substance is also composed of other smaller particles called molecules. A molecule is the smallest unit of q substance, that can still exist as that substance before 1t Is broken down into the various atoms which compose 1t. According to an early theory each of the 92 elements has a different type of atom, and 1t IS the various combinations of these atoms that make up the different compounds and substances known in everyday life.
 Every atom of the same element is the same, in structure, shape, weight and behavior as every other atom of that element, but 1t is the difference between the atoms of various eleemnts which make these clements different. Every atom las similar structure, being com- posed of nucleus, in which are found protons or positive charges O. electricity and newtrons or neu- tral units. In every atom there are also free electronS which revolve around the nucleus in paths called planetary orbits.
 These atoms have different atomic weights, which represent their weight in comparison with the weight of the oxygen atom wNch is 16. The atomic number of an atom represents the number of protons in the nucleus, and therefore the planetary electrons. In combining with the atoms of other elements to form compounds each atom tries tJ complete its outermoSt ring of e.:ctrons by giving up or gaining them. The number of electrons which an atom of an elements will tend to give up or gain Is called its valence.
 Tn the models in the display, the students have shown molecules of various well known compounds. Each model shows the different ele. mentS which make up its molecule, as well as how the atoms join to- gether by their lending or borrow ing oe planetary electrons, to form compounds"

 Returns to Studies
 Robert Brownell, son of Mr. and Mrs. Lincoln Field Brownell of Chestnut Grove Road returned on Thursday to his studies at New York Military Academy Cornwall-on- Hudson, N. Y.
 Cadet Brownell, who entered the Military Academy this fall has been made a member. of the academy swimming team. During the season the team journeys to West Point Military Academy to engage in swimming meet with the Plebes there. Other meets on the seasons schedule are at Columbia Uniyer- sity, N. Y. and BlairstOwn Academy, Blairstown. N. J.
