property—contractility—a capacity by which its substance may 
be shortened or lengthened from the action of stimuli. The 
must always be the result of some stimulus, from within or with- 
out, which excites a manifestation of a peculiar organic capability. 
Postscript.—Since the above was written and mostly printed, 
we have received the November No. of the Philosophical Maga- 
zine, which contains two recent communications by Dr. Martin 
Barry relating to our subject, “ A Main cause of discordant Views 
on the Structure of the Muscular fibril,” and ‘Further Re- 
marks on the Muscularity of Cilia.” These papers contain noth- 
ing but a reiteration of Dr. Barry’s former doctrines under, what 
he would perhaps think, better auspices. But we have failed to 
perceive anything new, or indeed anything but a restatement of 
his previously advanced opinions; neither do we think that Dr. 
rry has very satisfactorily stated the ‘main cause of discordant 
views” on the subject, although we do not think it doubtful 
wherein this cause really lies.
