AN ORIGINAL OR OFFICIAL WRITTEN OF PRINTED PAPER FURNISHING INFORMATION OR USED AS PROOF OF SOMETHING ELSE

PRACTICALLY ALL PAPERS MAYBE CLASSIFIED FROM THE STANDPOINT OF THEIR BASIR FIBER COMPOSITION INTO SETS OF FIBER MIXTURES

GROUND WOOD SULFITE MIXTURE

CHEMICAL PULP FROM DICOTYLEDONOUS WOODS

COTTON RAG OR LINEN RAG

ADDED TO PAPER TO IMPROVE ITS TEXTURE

DEALS WITH THE APPEARANCE OF DOCUMENT

A DISTINCTIVE MARK OR DESIGN PLACE IN THE PAPER AT THE TIME OF ITS MANUFACTURE

MSRKS PRODUCED ON THE PAPER BY A FLEXIBLE WIRE

A TEST APPLIED WITHOUT CHANGING OR ALTERING THE PHYSICAL APPEARANCE

THIS TEST IS DONE ONLY IF SUFFICIENT SAMPLES ARE AVAILABLE AND IF PRIOR AUTHORIZATION FROM THE COURT IS REQUIRED

THIS TEST IS TO DETERMINE THE FIBER COMPOSITION, LOADING AND MATERIAL USED IN THE PAPER

THIE EXAMINATION IS PURELY MICROSCOPIC AND IT DETERMINES THE MATERIAL USED AND NATURE OF PROCESSING

GELATIN REAGENT

LESS RECENT

STILL LESS RECENT

THIS INK IS DEPENDENT ON THE INORGANIC SALT ADDED

COLOR OF LOGWOOD INK

INK MADE OF COAL TAR PRODUCTS

COLOR OF ANILINE INK

OLDEST INK MATERIAL KNOWN

COLOR OF INDIAN INK

TODAY MOST OF ALL COLORED INKS ARE COMPOSED OF SYNTHETIC ANILINE

MADE OF LIGHT FAST DYES SOLUTION IN GLYCOL TYPE SOLVENT

APPLIED TO DETERMINE THE COLOR AND PRESENCE OF ALTERATIONS AND ERASURES

A SIMPLE TEST WHEREIN DIFFERENT CHEMICALS OR REAGENTS ARE APPLIED ON THE INK STROKES AND OBSERVED

NO DEFINITE PROCEDURE WHICH CAN BE GIVEN FOR THIS DETERMINATION EXCEPT WHEN THE COLOR IS BLACK

THROUGH WATER MARKS AND IN CERTAIN CASES FROM THE COMPOSITION OF PAPER

IS UNNECESSARY WRITING WHICH IS NOT CAPABLE OF BEING READ USUALLY MADE ON CHECKS, PASSPORTS AND TRANSCRIPT

THE REMOVAL OF WRITING TO THE PAPER

THE OBSCURING OF WRITING BY SUPERIMPOSING INK

SUBSTANCES USED FOR INVISIBLE INK

TERM APPLIED TO PARTIALLY VISIBLE DEPRESSION

THIS WRITING USED SHEETS OF CARBON PAPER AND CAN BE MADE READABLE

BLANK PAPER MAY CONTAIN TRACES OF INK BECAUSE OF PREVIOUS CONTACT WITH SOME WRITING

A STRONG MARK PRODUCED BY PRESSURE THAT GOES BELOW THE SURFACE

A WEAK MARK MADE BY PRESSURE THAT STAYS ON THE SURFACE

A FAITHFUL REPRODUCTION OF AN IMPRESSION WITH THE USE OF CASTING MATERIALS

ANY MATERIALS WHICH CAN BE CHANGED FROM A PLASTIC OR LIQUID STATE TO THE SOLID CONDITION

ADD 1/2 TEASPOON OF SALT TO THE PLASTERE

ADD ONE PART OF SATURATED SOLUTION OF BORAX

TO GIVE A DRIED CAST BETTER DURABILITY

POOR MECHANICAL STRENGTH

TOOTH IMPRESSION

FOR TOOL MARKS

CAST OF FACE OR HAND

USED FOR BACKING THE HOMINIT

TEMPERATURE OF CAST FOR HUMAN

CONSIDERED TO BE ANY IMPRESSION, CUT, SCRATCH OR ABRASION

JUST AS THE MACHINE SURFACE OF A FIREARM ARE IMPRESSED

PRODUCED BY SINGLE APPLICATION OF THE TOOLIN THE ARE IF CONTACT

SERIES OF SCRATCHES PRODUCED BY A TOOL ACROSS THE SURFACE

WHEN A CRIME SCENE CONTAINS TOOL MARK EVIDENCE

DEFINING THE TYPE OF TOOL USED IN CRIME

MIGHT DISTINGUISH THE SAME TYPE OF TOOLS

THE ART OF EXTRACTING AND WORKING ON METALS BY THE APPLICATION OF CHEMICAL AND PHYSICAL KNOWLEDGE

BRANCH OF METALLURGY WHICH INVOLVES THE STUDY OF MICRO STRUCTURES

ARE COINS MADE TO IMITATE THE REAL THING AND USED FOR GAIN

COINS MADE IN MOLD

COINS MADE BY STRIKING OR STAMPING METHOD

ARE RESTORED BY THE APPLICATION OF ETCHING FLUID

IS THE BRANCH IF GEOLOGY WHICH DEALS WITH THE SYSTEMATIC CLASSIFICATION AND IDENTIFICATION OF ROCKS

FORMED FROM SOIL PARTICLES THAT ARE WASHED AND BLOWN

FORMED FROM THE DECOMPOSITION OF IGNEOUS AND SEDIMENTARY ROCKS

INACTIVE OR NON MIGRATORY SOIL

PRODUCED BY VOLCANIC OR INTENSED HEAT

HAD UNDERGONE CHANGE IN STRUCTURE AND TEXTURE

ROCKS FORMED BY SEDIMENT

INCLUDES UNDECOMPOSED ROCK FRAGMENTS

A FORM OF SILICA

WHITE AND REACTS WITH ACID

THEIR COMPOSITION GIVES RISE TO CLAY

WHITE MINERAL OBTAINED FROM SEDIMENTARY ROCK

A MINERAL THAT CRYSTALIZED IN THIN

A PRODUCT DECOMPOSITION OF PRIMARY MINERALS

ONE IF THE MOST VARIABLE OF ALL SOIL CONSTITUENTS AND IS OF PECULIAR IMPORTANCE

MATTER WHICH IS DRY AND IN FINELY DIVIDED FORM

DUST MIXED WITH WATER

WHEN THE DUST IS MIXED WITH THE SWEAT AND GREASE OF THE HUMAN BODY THIS IS FORM

EXTREMELY FINE DUST PRESENT IN THE AIR EVERYWHERE

PRODUCED BY THE WEAR AND TEAR

INDUSTRIES LIKE CEMENT AND GYPSUM FACTORIES

SOME OF THE FINELY POWDERED MATERIAL MAY BE FOUND ON THE CLOTHING AND FOOTWEAR OF EMPLOYEES
