of May in Denmark, and the latest were taken on the Ist of August. He gives the measurements 
of those in his collection as from 20 by 12:5 millimetres to 21:5 by 14:5 millims., one very small 
ege measuring only 7-5 by 5 millims. 
It is rather interesting to note the date of arrival of the Swallow in spring in the various 
parts of Europe. It arrives in Spain early in February, passes Malta early in March, is first seen 
in Italy about the 21st of March, is seen in Palestine about the middle of March, and is first 
observed on the northern shores of the Black Sea in April. In Northern Europe it arrives in 
the north of France and Belgium from the 5th to the 15th of April, and in the south of England 
about the same time, but does not appear in Scotland before the end of that month. In Denmark 
it appears about twenty days later than in Belgium; in Southern Sweden the first are seen from 
the 22nd to the 26th of April, but occasionally not till the first week in May. It does not appear 
at Roras, Nilsson says, till the 20th of May, and is not seen on the Dovrefjeld until the Ist of 
June.
