Abstract: A mounting device for holding a cooler in place on an external vertical surface of a vehicle or vessel, specially designed to accommodate coolers of the type which have a lid pivotally mounted on either side of a box at a (pushbotton) pivot. A pair of prongs on either side of the invention provide a pair of "U" shaped slots which slide between the box and the lid of the cooler, so that the pivots reach the bottoms of the two "U" shaped slots. An alternate embodiment provides a locking mechanism for holding the cooler in place once it has been slided onto the invention.

Abstract: Histidine derivatives of formula I are useful inter alia in peptide synthesis. ##STR1## wherein: X represents --CH.sub.2 OCH.sub.2 Ar, in which Ar is a phenyl substituent optionally substituted by one or more halogen, alkoxy, alkyl or nitro groups;Y, which differs from X, represents hydrogen, a protective group capable of inhibiting self coupling during formation of a peptide bond, an amino acid residue, a peptide chain or an antibiotic residue;E represents OH,OM,M representing an alkali metal or ammonium, OR, R representing an alkyl, aryl, aralkyl or alkaryl group, an amino acid residue, a peptide chain or an antibiotic residue;the compound I being optionally in the form of a hydrate or acid salt.In compounds I of especial interest, X represents benzyloxymethyl or p-bromobenzyloxymethyl, Y represents t-butyloxycarbonyl and E represents --OH.
