TitleCopy letter from Robert William Frederick Harrison, to the Manager, The International Aspirator Company
Date6 December 1907
DescriptionHarrison lists the defects that have developed in the aspirator recently supplied to the Royal Society - two of the mouth pieces have broken after only light use, and the machine casing has warped so much that it will not remain closed and the 'imperfect' catches will not hold it, so it must be tied together to prevent the sides falling out. He asks that they send someone as soon as possible to remedy the defects, which he takes for granted will be done at no charge.
