Sent from Ernest Warren
19 Jan 1903
Description:
'Dear Prof. Pearson,
One important thing I forgot to mention just now. I think it is necessary that Miss Radford should take some measurements which would give some conception of the size of the snail from which the radula was taken.
I suggest either:
(1) some measurement on the shell
(2) or the greatest diameter of the radula.
Possibly both (1) and (2) would be desirable.
For (1): (a) the greatest diameter of the mouth, (b) the distance between the apex of the shell and one corner of the mouth.
Could you think over this matter?
Yours very faithfully,
E. Warren.’
