Areolar Tissue
Drosera
June 22' 8° 15 Fibro-cartilage vertebræ of sheep.
3 sticks with Pins (I believe only elastic connective tissue) white soft stuff surrounding the vertebræ—
(23d. 8° well inflected)
(24' 8° 30' 2 of leaves beginning to reexpand, & the third perhaps so)
25' 8°, 2 of leaves quite expanded — 3d leaf nearly so does not much excite Drosera
27' 8° 3d leaf fully reexpanded
It is connective areolar tissue— showing characteristic wavy bundles clearing up on addn of acetic acid— & does not appear at all affected by the secretion of Drosera. (We ought to try this tissue in real digestive fluid.)
June 27th. One specimen is very much altered by the digestion— The other one also: but there appeared to be a good deal of elastic tissue in this specimen
