Mr Heape, Notes on the Proportion of the Sexes in Bogs. 141 
Bloodhounds show 1\54 fewer pups per litter than the Kennel 
Register gives. Basset hounds and Pointers are not represented 
in the figures given from the Kennel Register and it is these 
breeds which are chiefly responsible for the lower average fertility 
of the Larger dogs in the Schedule returns. The number of 
litters dealt with for Basset hounds is exceptionally large and the 
returns very complete, while for Pointers the returns are excep- 
tionally incomplete and the litters available for my purpose but 
a small proportion of the whole sent to me. Among Terriers, 
Scotch Terriers show about the same rate of fertility in both 
Tables, while the Schedule returns for Irish Terriers are ‘7 below, 
and for Dandie-dinmonts ‘46 above those of the Kennel Register.

The average of pups per litter of all breeds is ’53 in favour of 
the Kennel Register. In other words the rate of fertility shown 
in the latter is <3°/ 0 above what is recorded in the Schedules. It 
is the Basset hounds and Bloodhounds which are chiefly re-
