Supplementary memorandum submitted by
the Secretary of the Independent Scientific Group on Cattle TB
(P35A)
Further to Professor Bourne's letter of today's
date, to you, I have been asked to send you the table below as
the ISG will wish to refer to the figures contained in it when
discussing the TB99 questionnaire. Professor Bourne feels it would
be of value to your Committee to have the figures to hand.
