in consequence TI do not feel myself properly Qualified to review

this part of the subject, and would prefer not to deal with it if 4t

it falls to me (unless you would prefer to get someone in a better

‘position than me to cover both the bacterial-and viral fields; if
you did wish to I should of course quite understand your position).

I shall, however, continue to brood upon wha t would be a suitable
presentation, and tf you really want me to have a go, despite my

«limitations, “1 might perhaps prepare a skeleton and send it to you
‘to see if 1t seemed the kind of @pproach which would be suitable.
