             Appeal from the United States District Court
               for the Southern District of Mississippi
                           (2:97-CV-265-PG)


                           August 31, 1999
Before SMITH, BARKSDALE and PARKER, Circuit Judges.

PER CURIAM:*

     Plaintiff, Regan & Regan L. P. Gas Co., Inc. (“Regan & Regan”)

appeals the summary judgment entered for defendant, Level Propane

Gases, Inc. (“Level”) in this negligence action.       We affirm.

     Regan & Regan brought suit in Mississippi state court against

Level alleging that an employee of Level failed to close a propane

loading valve at Regan & Regan’s facility, which leaked and caused

a fire.   Level removed the case to federal court on the basis of

diversity.


     *
      Pursuant to 5TH CIR. R. 47.5, the Court has determined that
this opinion should not be published and is not precedent except
under the limited circumstances set forth in 5TH CIR. R. 47.5.4.

                                  1
     The     district   court   excluded     the   testimony   of    Regan’s

designated    expert    witness,   finding    that   his   experience    and

methodology failed to qualify him as an expert and that his

testimony was “speculative and unsupported by necessary facts,”

citing Federal Rule of Evidence 702 and Daubert v. Merrell Dow

Pharmaceuticals, Inc., 

(1993).2           The district court

then granted summary judgment for Level, finding that Regan &

Regan’s negligence theory was too tenuous to be submitted to a

jury.

     The following facts are undisputed.             The fire at Regan &

Regan’s facility was caused by not more than seventeen gallons of

propane leaking from a partially open valve at the end of a hose.

Level’s employee had unloaded propane through that valve thirty

hours before the fire broke out.     Witnesses at the fire observed an

8 to 10 foot tall flame coming from the end of the hose attached to

the valve.

     Level’s expert conducted tests and concluded that a valve left

open 30 hours earlier could not have produced an 8 to 10 foot tall

flame, given the stipulation that only 17 gallons of propane were

involved in the fire.      Rather, the fire would have had to begun

within an hour or two after the valve was left open.                Further,

engineering principles concerning dissipation rate, patterns and


    2
      In the Summary of Argument portion of Regan & Regan’s brief,
they state, “Charles Quick’s testimony should not have been
excluded.” However, because this argument was not briefed, it has
been abandoned. See Yohey v. Collins, 

, 225 (5th Cir.
1993)(holding that appellant abandoned argument by failing to argue
it in body of brief.)

                                     2
combustibility of propane confirmed the impossibility of a thirty

hour   delay    between   the   beginning   of   the   leak   and    the   fire.

Finally, Regan & Regan could not dispute the possibility that a

vandal or one of their own employees might have opened the valve.

       Regan & Regan argues that the grant of summary judgment should

be reversed because they have a right to cross-examine Level’s

expert before a trier of fact concerning whether or not the tests

he conducted adequately reproduced the conditions at the time of

the fire.      The district court found that, without the testimony of

an expert, Regan & Regan has not presented sufficient evidence to

support a jury verdict by a preponderance of the evidence.                   We

agree.    Mississippi law is clear that proving “possibility” or

leaving the issue to surmise and conjecture, is not sufficient to

sustain a verdict in a tort action.         See Hertz Corp. v. Goza, 

, 660 (Miss. 1974).       Regan & Regan has failed to present

sufficient evidence to create a fact issue on the allegation that

Level’s negligence caused the fire.         “A mere scintilla of evidence

of negligence is insufficient to make a jury issue.”                

foregoing reasons, we affirm district court’s grant of

summary judgment for Level.

       AFFIRMED.
