Philip O. Gravelle, a chemist, developed a
comparison microscope for use in the
identification of fired bullets and
cartridge cases with the support and
guidance of forensic ballistics creator
Calvin Goddard.

cope
People find or take out some bullets out
of someone’s hands or legs and check the
bullet with a microscope and match the
bullet with the gun they found so they
could catch the murderer or the thief.
A fire alarm examiner can compare the
unique characteristics of the riffle barrel
to the bullet by firing the test bullets from
the suspective weapon and then
comparing from the evidence bullet to
the test bullet a comparison microscope
is then used to more closely examination
striation on each bullet to see if there is a
match.

Problem solved
The microscope helps us to match a
bullet with a gun. The microscope helps
us to see something better or clearer
than a magnifying glass. The microscope
is also helpful or useful if you need to
look at something very small for example
to see if there are any germs or bacteria
etc. To compare the similarities and
differences of any object under the
microscope. A comparison microscope
can also be used to compare a hair.
For example if there is a murder then the
police will need to find the gun. After the
police have found the gun they would
give the gun to the examiner who would

Comparison microscope
Fired Bullets
Cartridge cases
When a crime happens then the police goes there
and checks if there are any bullets and cartridge
cases. The police then collect and takes the fired
bullet and cartridge cases (evidence bullet) to the
forensic lab. The police then requests the examiner
to use instruments like the comparison microscope
to match the bullets with the gun.
Microscope
Match
Gun
The microscope can tell the expert examiner if
the evidence bullet and the cartridge cases
match with the gun they had found.
Examiner
Evidence
Comparison
The examiner compares the evidence
bullet and cartridge cases with the bullets
and cartridge cases they have test fired
from the gun. The examiner uses the
comparison microscope for comparison of
marks on the evidence bullet and the test
bullet.

put the gun under the microscope to look
for any fingerprint. The police would then
take some fingerprints of the people who
they have a doubt on and match it with
the fingerprints on the gun. The examiner
can therefore solve the problem of
finding the murderer if the fingerprint on
the gun matches with the fingerprint of
the person who they had a doubt on.

Once I had a itching in my body. When I
went to the doctor, the doctor took a
blade and scraped some of the infected
area of my skin. Then I saw her looking at
it from a microscope. After observing the
skin under the microscope she told me
that I had a fungal infection. So without
the microscope the doctor wouldn’t be
able to tell me that I had a fungus
infection.
I think that the microscope affects the
society the most because if there were no
microscopes then people wouldn’t be
able to compare things. For example
microscope help us to compare evidence
to punish the people who committed
crime or to find out if the body has any
disease or not. Microscope is therefore
useful to us.
Another reason why I think that
microscopes affect the society is because
if someone can’t see something clear
enough with a magnifying glass then they
can use a microscope to magnify small
things even more.

Writing from where I got the highlighted parts:
When a crime happens then the police come to check if the bullet was there. Then the
police collects` the fired bullet to the forensic lab. Then the police tries to find the gun
from which they think the bullet came from. Then the forensic expert examiner fires

another bullet from the gun that the police has brought. The examiner then places
both bullets- (a) evidence bullet and (b)test bullet under the comparison microscope
to match the two bullet. If the patterns on the two bullets are similar, they can be
seen at the same time under the comparison microscope clearly. Under ordinary
microscope only one object can be seen at one time. To compare, we have to remove
the first object and place the second object. We have to depend on memory to
compare the two objects.
Definitions:
Fired bullet – The bullet that the murderer shot.
Evidence bullet – The bullet that the police found that was shot by the murderer
(fired bullet but as an evidence).
Examiner – The expert person who gives advice about the evidence or a dead body or
the bullet (tells the police if the bullet matches with the gun or not).

In conclusion, now you know how important the microscopes are. If you have a new job of working at
the police then you should for sure use the microscope to find murderers and give them their
punishments.
