We report the detection of the Hi line at 21 cm from the circumstellar shell around the AGB star X Her using the position-switching technique with the Nan¸cay RadioTelescope. At the star position the line shows 2 components: (i) a broad one (FWHM 13 kms?1) centered at ?72.2 kms?1, and (ii) a narrow one (FWHM 4 kms?1) centered at ?70.6 kms?1. Our map shows that the source associated to the broad component is asymmetric with material flowing preferentially towards the North-East. This source extends to 10? ( 0.4 pc) from the star in that direction. On the other hand, the narrow component is detected only at the star position and indicates mate-rial flowing away from the observer. The total mass of atomic hydrogen is 6.5 10?3 M? which, within a factor 2, agrees with the estimate obtained from IRAS data at 60 ?m
