Examined * which had been in Raw Meat 7 hrs

Gland unaltered: number of minute spicks in th somewhat increased & one fair sized ball of proto has formed ─ But no aggren like CD showed me in study.─

June 30 ─ 9.50

Examined * which had been in raw meat for 24 hrs nearly the number of spicks is increased since last night I believe, at any rate, it is very much increased compared with what it was when the leaf was fresh ─ But a lump? noticed last night has not changed its shape which does not look like being protoplasm

Examined one of the leaves in distilled water in water, it is in much the same sate as the one that had been in raw meat.

Examined one of the leaves in ammonia = here there is more aggregation & of a different character than in the water or raw meat ones.

No movement in 5 hrs in a mass of aggn in an ammonia leaf
