An attempt was made in a previous paper* to bring home to glass manufacturers as well as to scientific workers the importance of manufacturing or using a glass which is as little affected as possible by the substances with which it comes into contact, whether gaseous, liquid, or solid. The subject is but little less important to the manufacturer of common bottles than to the maker of scientific glassware, and our experience during the past twelve months has not inclined us to lessen the emphasis laid on it; and in view of some of the expedients which are now and then adopted when a furnace is not working satisfactorily, it is essential to bear in mind that the addition of more than a certain proportion of soda intended to soften the glass for working.
