1. I believe the answer is William Herschel.

Francis Galton is often credited with the discovery that everyone's fingerprints are unique and that they could therefore be used for identification. However his works is extensively based on the work of Dr. Henry Faulds, who appears to have a better claim to the discovery, along with British magistrate William Herschel.

2. I believe that the ratio of height to width indicate size and consistency in hand writing analysis. The ratio of height, width and size of letters is among the characteristics of handwriting analysis that entails whether the letters are consistent in height, width and size.

3. I believe the statement that describes the line quality in handwriting analysis is whether the letters are shaky or flow continuously. Line quality is an indication of speed and fluency; the better the quality, the more skilled, or at least fast, the movement of the pen.

4. The statement that best indicates pen pressure in hand writing analysis is the down strokes and upstrokes are an even width.

Pen pressure is the pressure equal or unequal when applied to upward and down ward strokes. The pen pressure of a writer indicates his physical and emotional energy.

5. I think what is measured in the ridge count is spacing between ridge lines.

Ridge counting is the the counting of the ridges that touch or cross the line of count drawn between the delta and core of loop patterns. A white space must always intervene between the delta and the first ridge to be counted.
