Xanthull v. State
In Xanthull v. State (403 SW.2d 807) the defendant was convicted of the burglary 
of a lumber company. A hammer on the floor behind the counter at the crime scene 
had been used to pry open the cash box and the defendant's palm print was found 
on the hammer. As in Kuhl, the deputy (who qualified as an expert in fingerprints 
based on his education, training, and experience) testified that palm prints were 
"biologically the same as the bulbar ridges on the end of the finger". The issue 
on appeal involved the question "was the court in error in allowing a fingerprint 
expert to testify on palm prints". The court (Court of Criminal Appeals of Texas, 
1966) held that because he was qualified as a fingerprint expert and fully 
explained the fundamental similarity between fingerprints and palm prints, the 
court did not err in permitting him to testify as an expert on palm prints.

Xylene and Xylene Substitutes
A laboratory solvent used as a carrier in reagents, also used as a clearing agent.  
Xylene is considered a hazardous chemical.  Over exposure can produce 
headaches, nausea or dizziness.  Xylene substitutes are available under
different names that are less hazardous to the user.

Xylene is also known as xylol, dimethylbenzene, or mixed xylenes.

ZIMOX(YS)
A system used in South Africa to further sub-divide single fingerprint classifications 
based on ridge count whereby each symbol Z,I,M,O,X,Y,S indicates a ridge count within 
a certain range. E.g. Z = ridge count of 1-4, I = ridge count 5-8 etc. Used until AFIS 
automation in 2002.

Zar-pro
A method developed by Jessica Zarate to lift and visualize fingerprint images left in 
blood.  Zar-pro is a florescent protein lifting strip made of titanium dioxide and 
fixative, available since 2010 and published in the 2011 May/June issue of the Journal 
of Forensic Identification.  Due to protein being present in latex gloves, Nitro gloves 
must be used. The images lifted are in reversed position.  Weak images may get stronger 
with time.  Over long periods of time, images may fade so photographing the images is 
needed. Zar-pro is nontoxic and can be used on both porous and nonporous items.

Zinc Chloride
A fluorescent technique used to develop friction ridge detail on 
porous surfaces.  Also used to enhance latent prints that were 
developed with other methods.

A metal salt used to treat ninhydrin developed latent prints.
