he reports that the two which had been subjected to 
artificial gastric juice were “in that state of diges- 
tion in which we find connective tissue when treated 
with an acid, viz. swollen, more or less hyaline, the 
fibrillar bundles having become homogeneous and lost 
their fibrillar structure.” In the specimens which had 
been left on the leaves of Drosera, until they re- 
expanded, “parts were altered, though only slightly 
so, in the same manner as those subjected to the 
gastric juice, as they had become more transparent, 
almost hyaline, with the fibrillation of the bundles 
indistinct.” Fibro-cartilage is therefore acted on in 
nearly the same manner by gastric juice and by the 
secretion of Drosera. 
Bone. — Small smooth bits of the dried hyoidal 
bone of a. fowl moistened with saliva were placed on 
two leaves, and a similarly moistened splinter of an 
extremely hard, broiled mutton-chop bone on a third 
leaf. These leaves soon became strongly inflected, 
and remained so for an unusual length of time; 
namely, one leaf for ten and the other two for nine 
days. The bits of bone were surrounded all the time 
by acid secretion. When examined under a weak 
power, they were found quite softened, so that they 
were readily penetrated by a blunt needle, torn into 
fibres, or compressed. Dr. Klein was so kind as to 
make sections of both bones and examine them. He 
informs me that both presented the normal appearance 
of decalcified bone, with traces of the earthy salts 
occasionally left. The corpuscles with their processes 
were very distinct in most parts; but in some parts, 
especially near the periphery of the hyoidal bone, 
none could be seen. Other parts again appeared 
amorphous, with even the longitudinal striation cf 
bone not distinguishable. This amorphous structure
