ord's request, I made over this skull
to the Calcutta Museum.]

In addition to a careful study of De Blainville's 'Osteographie,'
where the bones are figured in large size to scale, I have made many
careful measurements of skulls belonging to myself and friends, and
also of the skulls and skeletons in the Calcutta Museum (for most
willing and valuable assistance in which I am indebted to Mr. J.
Cockburn, who, in order to test my calculations, went twice over the
ground); and I have adopted the following formula as a tentative
measure. I quite expect to be criticised, but if the crude idea can
be improved on by others I shall be glad.

I now give a tabular statement of four out of many calculations made,
but I must state that in fixing an arbitrary standard of 36 inches
for tail, I have understated the mark, for the tails of most tigers
exceed that by an inch or two, though, on the other hand, some are
less.

_Formula_.--Measure from the tip of the premaxillaries or outer
insertion of the front teeth (incisors) along the palate to the
nearest inner edge of the foramen magnum. Multiply the result by 5.50.
This will give the length of the skeleton, excluding the tail. Divide
this result by 2.50, and add the quotient to the length for the
proportionate amount of muscles and gain in curves. Add 36 inches
for tail.
