e conclusions of Mr, Tupman respecting the closing of 
the shower are of course set aside by the observations in Italy 
and England by those of Fredericton and Santa Barbara. 
17. The duration of the whole shower was at least twelve 
hours,and it appears to have been somewhat fitful in its ten- 
sity. Perhaps the apparent fitfulness may be due to the clouds, 
though we think that that is not the only reason. 
Thus after the time named by Mr. Tupman we have an in- 
creasing display shown by Prof. Bellucci’s numbers. At Cul- 
loden the report seems to carry this pay on two hours longer. 
€ numbers seen at Fredericton and Santa Barbara show a 
tolerably uniform continuance for several hours longer. There 
was little trace of the display on the next morning.
