THE Journal of Photography speaks of a photograph which is a wonder in the way of science. It is the Lord's Prayer photographed on a minute piece of glass. 

Many of us have seen photographs in which the Ten Commandments, the Declaration of Independence, or some other remarkable document, has been photographed on so diminutive a scale that it can be read only by a powerful magnifying-glass. Generally, a microscope of 20 to 50 diameters will bring out all the letters so clearly that they can be easily read. In the present case, however, the Lord's Prayer has been perfectly photographed on THE TEN-THOUSANDTH PART OF A SQUARE INCH, and so fine is the work that it will bear inspection with a good 1/6 objective and B eye-piece (i. e., a microscope that will magnify about 360,000 times).

To give the reader a clearer idea of this scientific marvel, the editor of the journal mentioned presents the following interesting facts: 

The Lord's Prayer, as recorded by Luke, contains 222 letters, and the whole Bible contains 3,566,480 letters. Consequently, by a very simple mathematical calculation, the Bible, if written in just the same sized letters, would fill a space 16,065 times that required for the Lord's Prayer. Therefore, if the Lord's Prayer can be photographed on the ten-thousandth part of a square inch, the whole Bible could be photographed on a trifle more than one and a half square inches! How wonderful! According to this, a surface equal in area to the two sides of a common silver dollar would more than contain a photograph of every word in the Bible, so plain that it could be read by a powerful microscope!

A common postal card contains 15.39 square inches. On this, says the authority mentioned above, the entire Bible, from Genesis to Revelation, could be photographed nearly ten times!

Truly, the present is an age of scientific wonders. The words of prophecy are “fulfilled," Many shall run to and fro, and knowledge shall be increased." But far more precious and wonderful is the thought that "God so loved the world that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life." Youthful reader, is the image of Jesus photographed on your heart?
