My dear Sir
I send you a portion of the fluid containing gold particles of which I spoke to you last night - I hope it will arrive in good state1. Small circumstances cause the aggregation of the particles into floculi & then they settle much more quickly than before such change[.] Unless glass be exceedingly clean the matter on its surface tend to cause the change.
