Abstract This paper deals with the deuteros plous, literally ‘the second voyage’, proverbially ‘the next best way’, discussed in Plato’s Phaedo, the key passage being Phd. 99e4-100a3. I argue that (a) the ‘flight into the logoi’ can have two different interpretations, a standard one and a non-standard one. The issue is whether at 99e-100a Socrates means that both the student of erga and the student of logoi consider images (‘the standard interpretation’), or the student of logoi does not consider images (‘the non-standard interpretation’); (b) the non-standard one implies the problem of the hypothesis, a problem analogous to the problem of the elenchus; (c) there is a structural analogy between Descartes’ ontological argument for the existence of God in his 5th Meditation and the final proof for the immortality of the soul in the Phaedo.

In September 1913 some two hundred teachers of Latin assembled at Cambridge to study the Direct Method. There was much demonstration, experiment, and discussion: there was great enthusiasm. I best remember one thing. W. L. Paine had brought a class of about a dozen Whitgift boys who had one year's Latin behind them. I was interested in their keen enjoyment of the work, their eagerness to speak and answer. But what surprised me was their accuracy. A boy was called out at the end of the lesson to write up on the board the story which, mainly by question and answer, had been put before the class: he did it with almost no mistakes, and quite quickly. Any such blunder as the confusion of nominative and accusative had met, as the lesson proceeded, with a chorus of immediate correction: but I was still surprised at the final proof of a far higher degree of accuracy at that stage than I had ever seen or believed to be possible. This shows that Dr. Rouse was not a lone magician, of infinite resource and sagacity, who had invented an instrument which only he could use. The Whitgift boys were quite as good as the Perse boys. Paine was a scholar, but of nothing like Dr. Rouse's quality in scholarship. He was a well-qualified Latin master, who had taught on old lines at Oundle and found the whole business abominably dull. After experimenting with oral work in a less degree, he was encouraged at Whitgift to adopt the Direct Method: there he found himself.

Conflict-Driven Clause Learning algorithms are well known from an engineerpoint of view. Thanks to Minisat, their designs are well understood, and mostof their implementations follow the same ideas, with essentially the samecomponents. Same heuristics, fast restarts, same learning mechanism.However, their efficiency has an important drawback: they are more and morelike complex systems and harder and harder to handle. Unfortunately, only afew works are focusing on understanding them rather than improving them. Inmost of the cases, their studies are often based on a generate and testpattern: An idea is added to an existing solver and if it improves itsefficiency the idea is published and kept. In this paper, we analyse``post-mortem'' the proofs given by one typical CDCL solver,Glucose. The originality of our approach is that we only consider it as aresolution proofs builder, and then we analyze some of the proofcharacteristics on a set of selected unsatisfiable instances, by shuffling each ofthem 200 times. We particularly focus on trying to characterize useless anduseful clauses in the proof as well as proofs shapes. We also show thatdespite their incredible efficiency, roughly 90% of the time spent in aCDCL is useless for producing the final proof.

References to the O'Odham tribe were written as O'Odhams. The correct form is O'Odham. The error was introduced after the final proof had been approved by the author.

A third species has been added to the typhus group of rickettsiae. This new rickettsia was isolated from Haemaphysalis leporispaluslris ticks removed from indicator rabbits in the vicinity of Richmond, Ontario. Inoculation of tick suspensions into embryonated hens' eggs was the method of culture. Results of complement fixation tests with guinea pig, hamster, and rabbit antisera showed that it is a member of the typhus group while results with antiserum prepared in mice suggested that it is different from the two known species, Rickettsia typhi and Rickettsia prowazeki, in the group. Results of toxin neutralization tests furnished the final proof that this is a new species of rickettsia. The name Rickettsia canada is proposed for it.

Isoenzyme patterns of normal adult Nippostrongylus brasiliensis were compared with those of damaged worms permanently affected by immunity and adapted worms which show increased resistance to immunity.Isoenzymes of acetylcholinesterase, found in glands of the head end of the worms, showed changes in damaged and adapted worms which can be related to the effects of immunity.Aminopeptidases and non-specific esterases from the same glands were unchanged in worms affected by immunity.Isoenzymes of acid phosphatase found in the gut of the worms were altered in damaged and adapted worms; these changes are probably secondary to the changes in acetylcholinesterases.Of the enzymes studied, acetylcholinesterase is the enzyme most likely to be the antigen which stimulates host immunity, but final proof of this is required.We are most grateful to Dr Valerie E. Jones for many helpful suggestions.
