     Per Curiam.  John McCabe, a prisoner of the commonwealth
               

of  Massachusetts,  appeals  the  district  court   grant  of

defendants'  motion  for  summary  judgment  on  his   claims

pursuant  to 42 U.S.C.    1983.1  McCabe  alleges that, while

incarcerated at the Treatment  Center for Sexually  Dangerous

Persons  at   Bridgewater,  he  was  subject   to  mechanical

restraints in  violation of the eighth  amendment prohibition

of  cruel and unusual punishment.  He further alleges that he

was  deprived of  his constitutional  right of access  to the

courts because of restrictions placed upon  his access to the

law library.

     We believe  that the district court's opinion adequately

sets  forth the  background of this  case, and  that McCabe's

serious assault on a guard amply justified the restraints and

disposes of the eighth amendment claim.

     As  for the denial of  access to library facilities, the

gravamen  of McCabe's  claim, as  set forth  in his  brief on

appeal, is  that  the  restraints  interfered  with  McCabe's

ability  to use the library.   Because McCabe  admits that he

was not wholly denied  access, he has no claim  under section

1983  without a  showing  of actual  prejudice,  such as  the

forfeit of a case for failure  to meet filing deadlines.  See
                                                             

                    

1.     The   district   court   ordered   plaintiff's  claims
"dismissed."   However, since the court  explicitly relied on
defendant affidavits and on the record, we treat its decision
as a summary judgment.  See Fed. R. Civ. P. 12(b)(6).
                           

Sowell v. Vose, 941 F.2d 32, 35 (1st Cir. 1991).   But McCabe
              

fails  to make any such allegation of actual prejudice either

in his complaint or in his brief on appeal.

     Accordingly, we  affirm the district court  on the issue

of  library access for lack of any claim of actual prejudice.

We  note that McCabe is  now in another  institution, and has

conducted extensive litigation under  new conditions, so that

the  library  access  problem   of  which  he  complains  has

apparently been resolved.

     Affirmed.
