    PROF. RAMSAY has been good enough to forward to us the following translation of a passage in a letter he has recently received from Prof. Olszewski: “I have at last succeeded in determining the critical temperature and the boiling-point of hydrogen. I have found for the former –233° and for the latter –243°. I have used the dynamical method, which I described in the Philosophical Magazine. A thermal couple tproved of no use, and I was obliged to avail myself of a platiniim-wire thermometer, measuring the temperatures by the alteration in resistance of the wire. I have obtained satisfactory results, and intend to publish an account of them in English.”
