The preparation and properties of some new β-alkylamino-butyric anilides have been described and a summary report on some of their pharmacological properties is given. Two derivatives (the p-(carbo-n-butoxy)-anilides of β-diethylamino- and of β-(1-piperidino)- butyric acid = XVI and XVIII) show promise as very active local anaesthetics with low toxicities. One derivative (β-N-pyrrolidino-n-butyric
