Quaternary structures of the astaxanthin-proteins of Velella velella, and of α-crustacyanin of lobster carapace, as revealed in electron microscopy

Abstract: 1. 1. The astaxanthin-proteins of the mantle of Velella velella and of the carapace of Homarus gammarus (L) have been studied in electron microscopy. 2. 2. While there is ambiguity in interpretation of the electron micrographs, possible quaternary structures for the pigments are proposed.

The Ethical Importance Of Sympathy1

Abstract: It seems natural enough to suppose that there must be some very close connection between our feelings of sympathy and our moral principles. A large part, at any rate, of the badness of bad men seems to consist in their lack of real concern for other people, and a large part of the goodness of good men consists in the regard they have for their fellows. Could a man who never felt with of for another be regarded as good, or even as a moral being at all ? We should be inclined to say that this was impossible were it not that some philosophers appear to maintain that reason is the fundamental moral requirement and that unsympathetic beings might act rightly from some purely rational principle. Kant, for example, in a well-known passage, contrasts the man who helps others because he is sympathetically inclined towards them with the man who is too unhappy to feel with them but nevertheless helps them because he thinks he ought to. It is the second of these men, in his view, whose action is most clearly moral. In reply to this we may say that although a man's personal griefs at a particular time may render him at that time unable to feel with others even though he helps them as he ought, nevertheless he could not have performed such an act of heroic beneficence if his heart had never warmed towards anybody.

The Date of Porphyry's Kata Xpiσtianωn

Abstract: The only evidence we have concerning the date of Porphyry's is that it was written during his stay in Sicily, which lasted from 268 until his return to Rome after Plotinus’ death in 270. How soon after is unknown. Castricius’ lapse from the vegetarianism of the Plotinian school and Porphyry's attempt to recall him to the fold with De Abstinentia should presumably be placed after Plotinus’ death, and Porphyry was still in Sicily at the time. Cassius Longinus’ letter from Phoenicia, apparently written after Plotinus’ death, seems to have found Porphyry still in Sicily. Thus he may still have been there in 271, or possibly even later. There is nothing to support the common view that he returned to Rome immediately or even soon after Plotinus’ death.
