Abstract
PROF. STANLEY ALLEN has put forward a very satisfactory working hypothesis to account for the presence of these early English instruments at St. Andrews. The additional plate supplied by John Marke proves that the Cole astrolabe was in the hands of this eminent maker in London about the time when Prof. Gregory was collecting scientific instruments there. May I add that the finest picture of Cole's great astrolabe was published in colour in the Illustrated London News for Aug. 14, 1926.
