| Description | (Copy) by Davies & Brook, Warrington, to Messrs. Potts & Roberts, Solors., Chester, saying that Mathieson & Co. had given them a letter from Potts & Roberts asking for permission for Dr. Grace Calvert to inspect their Works "with a view to Sir R.Brooke taking such proceedings as may be advised". This is an unusual request. If permission is granted, a chemist, equally eminent with Dr. Calvert, must accompany him. Paper. |
