Some time since you sent an instrument here on Dr Edridge-Green's behalf. When it arrived we knew nothing at all about it (not having been advised by Dr. Edridge-Green) and, accordingly, declined to take it in. We have since had from Dr Edridge-Green an explanation of the matter and are now anxious to have the instrument sent here. May I trouble you to forward it at an early opportunity?
