It must also be stated that responses are given to any of the luminous rays of the spectrum when these are employed separately; but that neither the non-luminous rays beyond the red, nor those beyond the violet, appear to exert the smallest degree of stimulating influence.

Electrical Stimulation.

All the excitable parts of all the Medusæ which I have examined are highly sensitive to electrical stimulation, both of the constant and of the induced current.

Exploration with needle-point terminals and induction shocks of graduated strength showed that certain parts or tracts of the nectocalyx are more sensitive than others. The most sensitive parts are those which correspond with the distribution of the main nerve-trunks, i.e. round the margin of the nectocalyx and along the course of the radial tubes. The external or convex surface of a nectocalyx or umbrella is totally insensitive to stimu. . . Read More

I wanted to read this before the new Netflix adaptation comes out later this year.

I found it quite slow paced but things do pick up in the last 100 pages. I still love Austen's writing, humour and wit but didn't care as much about this book compared to Emma and Pride and Prejudice.

I’m a firm believer in reading a book before the movie comes out. In this case, I revisited Persuasion, by the incomparable Jane Austen before the 2022 movie. Say what you will, but I think you can get something new out of a Jane Austen novel every time you return to it. Persuasion is a good reminde

We live at home, quiet, confined, and our feelings prey upon us.

Perhaps many this year have inwardly uttered similar sighs, more or less confined to their house, weeks without a chance to see friends or loved ones turning into months, perhaps even missing the everyday routine of having a chat at the

Jane Austen understood that nothing is sexier than standing seven feet away from someone, making brief eye contact, and then going home. You got to love her for that.

One of the major sources of contention and strife in my marriage is the disagreement between my wife and me over what is the best Jane Austen novel (yes, we are both more than a bit geekish in our love of words and literature--our second biggest ongoing quarrel is about the merits of the serial comm

Jane Austen never disappoints me! This was the first time I've read this book, and, since it's one of her less popular novels, I didn't know what to expect. However, I quickly was swept up into the story and felt all of Anne's emotions like they were my own. I really enjoyed how, unlike the other Au

Jane Austen is ruthless and brilliant; she is sarcastic, subtle and superbly witty. She writes in such a matter of fact way that the absurdity of her characters is in plain sight. Sir Walter Elliot is a complete fool. Austen doesn’t need to tell her reader this, she shows it to them. The man is comp
