Abstract
ALTHOUGH orthorhombic magnesium sulphate heptahydrate (epsomite) has been the subject of two previous investigations,1,2 in neither case was a complete structure proposed. We commenced work on this substance in the hope of carrying the knowledge of its structure to a more complete stage. Due to unforeseen circumstances, however, the investigation has been interrupted, and it is uncertain when the study can be resumed. We have considered it of interest to report some of our results, since they agree with those already in the literature, and thus serve as a third check on the dimensions of the unit cell and on the space-group.
