(Ch. III)
Nov 15 8° Am 2 leaves in very strong sol. of C. of Ammonia
8° 30' darker spec plenty of aggregation
11° 40' — still aggregated masses
Nov 16' 7° 30' Am— The oblong balls of P are now opake & granular, but retain nearly as perfect an outline as ever (Perhaps solution too strong)
But I now clearly see that (like too Hot water) the very strong solution has prevented very perfect aggregation, for towards bases of all t' there are only innumerable very small spheres, & in upper parts most of the masses are oblong
It is rather important that very strong sol. of C. of A.' does not cause perfect aggregation. i e. [illeg] minute spheres left like Boiling water.
