Summary Waterbuck were darted with the new “Hypodart” fired from the crossbow, and with the “Cap‐Chur” gun. Eleven waterbuck were successfully immobilised with M.99 alone. The remaining 37 received M.99 in conjunction with an ataractic, acetylpromazine maleate. Hyoscine hydrobromide, a parasympatholytic drug, never formed part of the immobilising dose and was given to only five of the immobilised animals. Not only is this drug unnecessary; its use is a positive disadvantage and was responsible for the death of one waterbuck. Three other waterbuck died, two of these probably from heat stroke, a consequence of using acepromzine on a hot day. The remaining animal damaged a leg when trying to get up and was killed by lion five days later. This paper gives justification for combining M.99 and acepromazine in the approximate ratio of 1:1 for the immobilisation of this species, and suggests that the losses experienced by other workers through torticollis may well have been the result of the acepromazine.
