Definition:
(a.) Forming an exception; not ordinary; uncommon; rare; hence, better than the average; superior.

(4) No monosynaptic connexions were found between anterodorsal and posteroventral muscles except between the muscles innervated by the peroneal and the tibial nerve.
(5) Other haematological parameters remained normal, with the exception of the absolute number of lymphocytes, which initially fell sharply but soon returned to, and even exceeded, control levels.
(6) When the concentration of thrombin or fibrinogen was altered systematically, mu T and mup were found to mirror each other except when the fibrinogen concentration was increased at low thrombin concentrations.
(7) The penicillin-resistant Enterococcus hirae R40 has a typical profile of membrane-bound penicillin-binding proteins (PBPs) except that the 71 kDa PBP5 of low penicillin affinity represents about 50% of all the PBPs present.
