Note 114 — HISTORICAL INTRODUCTION. (continued 2)

The Chemical Laboratory at Cambridge has produced some valuable discoveries. Ex pede Herculem, let me remind the chemist of the formation of Nitrous Acid, by passing a current of ammoniacal gas through the heated Oxyd of Manganese, for which we are indebted to Dr. Milner. I mention it merely as a whimsical circumstance, that the greatest degree of cold ever produced, was effected at Oxford, and the highest temperature, lately, at Cambridge. The researches of Dr. Clark are highly interesting and important, a succinct account of which has been published in a small work, entitled, “The Gas Blowpipe, or the Art of Fusion, by burning the Gaseous constituents of Water.”
