Dear Doctor Watson: 
I had a long talk with Professor 
Goodale last night about the Herbarium and Holm’s 
mission to Garnbridge, and I find that loe had quite 
misunderstood the amount of work which would be ne- 
cessary upon the Herbarium. I had not thought that 
it would require more than six weeks or two monthSm 
When it comes, however, to a question of detailing 
Professor Ward's Assistant for a year or more^it 
raises serious difficulties, and I think that possi- 
bly we had better withdraw our request for a share 
of the Herbarium: at all events, it vjill be impos- 
sible for Holm to do it, and I will recall him at 
once.
