Theyare sometimes construct-ed in the form of Fig. 38,when they answer betteras receivers. But whenthey are intended for boil-ing liquids, the more preferable form is that of Fig. 39. The form , though quite common, is inconvenient for solutions, because whenthe mass is to be removed a part of the matter not dissolved remainsnear the commencement of the neck, which shouldespecially be avoid-ed in an analysis. These vessels should be made of very thin glass and ofuniform thickness. When they are placed upon the sand-bath they may be covered with a watch glass properly ad-justed ; and when the belly is a little larger than the mouththey answer very well even though the liquid, which isboiled, be violently agitated. In such a vessel also theportions which are not dissolved can be easily removedand thrown upon the filter. • The oil bottle or Florence flask may in many cases besubstituted for the
