For measuring quantities less than two flnidouneesthe cone-shaped graduates will be found preferable to the tumbler-shape, but difficulty is often encountered in cleaning them properly,particularly the smaller sizes. The Acme graduates, introduceda few years ago, possess the advantage of being made flat on thebottom, without a foot, and hence are less liable to be upset orbroken ; they arc admirably adapted for laboratory work, are cylin-drical in form, of about the same diameter as tumbler-shape gradu-ates, and can be had for both metric and apothecaries fluid measure.(See Figs. 20 and 21.)
