By referring to Table I it will be seen that on all the beds 
in Tangier Sound, from Fishing Bay down to the Great Bock, 
with one exception, that of Chain Shoal, the maximum ratio 
is that of the second class to the first. The inference is that 
there was a successful spatting season on all the upper beds 
in 1876 or 1877, probably the former. 
Again, the minimum ratio, as far down the Sound as the 
Mud Bock, is that of the third class to the second, showing 
that on the beds above the Mud Bock there was not a suc- 
cessful attachment in 1878, which was the case as attested by 
ourselves. The remaining ratios on these beds show that 
there has been some attachment during the present season. 
Leaving the Chain Shoal Bed for the present, the minimum 
ratio on all the remaining beds is that of the fourth class to 
the third, showing that there has been but little attachment 
of young during the season of 1879. 
The remaining ratios show that there was a partial attach- 
ment of young on the beds between Turtle Egg Island Bock 
and the Great Bock during 1878, and a partial attachment 
on the remaining beds north of Jane’s Island during 1876 or 
1877, while there was a successful spatting on those lower 
beds during 1878, which conclusion was found to be correct 
by our observations during that season. 
Arranging these deductions in tabular form, we have the 
following :

The Chain Shoal differs from the beds of its section, the

its moderately successful one in 1876 or 1877, while during
