Harry.launched.himself.across.the.floor.and.grabbed.the.Death.Eater.around.the.knees,.causing.him.to.topple.and.his.aim.to.go.awry..Neville.overturned.a.desk.in.his.anxiety.to.help;.and.pointing.his.wand.wildly.at.the.struggling.pair,.he.cried:.

.Get.out.of.the.way,.Harry!..yelled.Neville,.clearly.determined.to.repair.the.damage..
Harry.flung.himself.sideways.as.Neville.took.aim.again.and.shouted:.
.STUPEFY!.
The.jet.of.red.light.flew.right.over.the.Death.Eater.s.shoulder.and.hit.a.glass‐
fronted.cabinet.on.the.wall.full.of.variously.shaped.hour‐glasses;.the.cabinet.fell.to.the.floor.and.burst.apart,.glass.flying.everywhere,.sprang.back.up.on.to.the.wall,.fully.mended,.then.fell.down.again,.and.shattered.‐.
The.Death.Eater.had.snatched.up.his.wand,.which.lay.on.the.floor.beside.the.glittering.bell.jar..Harry.ducked.down.behind.another.desk.as.the.man.turned;

.sprawled.on.his.back.on.the.table,.with.his.head.lying.inside.the.jar.full.of.glittering.wind..

All.three.of.them.raised.their.wands.again,.but.none.of.them.struck:.they.were.all.gazing,.open‐mouthed,.appalled,.at.what.was.happening.to.the.man.s.head..

The.Death.Eater.shook.his.ugly.head.again,.trying.to.clear.it,.but.before.he.could.pull.himself.together.it.began.to.shrink.back.to.babyhood.once.more….
