Phillip Rawer, of Stuttgart, j Germany, of a thousand pound eye, | which is to bo part of their £5000 human welfare, exhibit in tho Palace or Social Economy. Tho model of tho human eye, four" by six feet in si2e, will bo equipped with lenses, retina, and muscles, and will reflect tlio images of a largo model factory erected in front of it, showing tho various effects upon tho retina of light too dim or too glaring lights, and the consequent sudden contraction or expansion of tho pupil and of tho muscles of tlio eye, tlio object being to show the bad effect of badly lighted rooms upon tho nervous system, the digestion and the general constitution of" factory employees, and to demonstrate that it pays financially to light factories, offices, and workrooms properly. This exhibit will contain modols of factories which aro properly and improperly lighted, and models of eyes and other organs which have become diseased in various ways through the effects of poor lighting.

"Mary" entering tho door of a milk depot whero ■sho goes to work; "Mary" serving a child customer of tho shop, pouring milk into a pail; tho., child customer in. bed with typhoid; and last, a door with crepe on it, and tho legend below ''Mary" is a chronic typhoid bacillus carrier."

Tho hugo animated models of bacilluscarrying parasites, such as ticks, hugs, hnnso. and stable flies, will show how those insects become infected, and how they carry tho infection to human food, or directly to tWblood channels of the human body. Each cxliibit of such models will bo followed by exhibits illustrating the methods of fighting infection from those sources, such as methods of exterminating vermin, and the proper screening and rat-proofing houses. ■
