Royal Observatory Greenwich - GA requested Simms [William Simms, instrument maker] to give an estimate for Transit-Circles of different uses, and he encloses the estimates [no longer attached].

Royal Observatory Greenwich - The clock for the Northumberland telescope is nearly finished. Could WW get [James] Challis to send to [William] Simms or GA 'the breadth of the hole that is left by the side of the south pier of the polar axis for the clock weights to drop into; as that will determine the construction of our weights'. Could WW ask the President of the Council of the Cambridge Philosophical Society, whether they would present to the library of the Royal Observatory a copy of the Transactions of the Society. This will help bind the links between the Observatory and Cambridge.
