the least digested. There were also little free paral- 
lelograms of yellowish, highly translucent matter. 
Schiff, in speaking of the digestion of meat by gastric 
juice, alludes to such parallelograms, and says :— 
“ Le gonflement par lequel commence la digestion de la viande, 
résulte de l’action du suc gastrique acide sur le tissu connectif 
qui se dissout d’abord, et qui, par sa liquéfaction, désagrége les 
fibrilles. Celles-ci se dissolvent ensuite en grande partie, mais, 
avant de passer 4 l’état liquide, elles tendent & se briser en 
petits fragments transversaux. Les ‘sarcous clements’ de 
Bowman, qui ne sont autre chose que les produits de cette 
division transversale des fibrilles élémentaires, peuvent étre 
préparés et isolés 4 Vaide du suc gastrique, pourvu qu’on 
v’attend pas jusqu’a la liquéfaction compléte du muscle.” 
After an interval of 72 hrs., from the time when 
the five cubes were placed on the leaves, I opened the 
four remaining ones. On two nothing could be seen 
but little masses of transparent viscid fluid; but 
when these were examined under a high power, 
fat-globules, bits of fibro-elastic tissue, and some few 
parallelograms of sarcous matter, could be distin- 
guished, but not a vestige of transverse striae. On the 
other two leaves there were minute spheres of only 
partially digested meat in the centre of much trans- 
parent fluid. 
Fibrin.—Bits of fibrin were left in water during 
four days, whilst the following experiments were 
tried, but they were not in the least acted on. The 
fibrin which I first used was not pure, and included 
dark particles: it had either not been well prepared 
or had subsequently undergone some change. Thin 
portions, about +; of an inch square, were placed 
on several leaves, and though the fibrin was soon 
liquefied, the whole was never dissolved. Smaller 
particles were then placed on four leaves, and minute
