cthylnminc (nn activo principle of ergot) rcsults in n loss of nctivity. Tho introduction of tho ncctyl group into tho cholino rnolccule convcrts this conipnptivcly inert substnnco into n powcrful hcnrt poison. Highly intcrcsting is tho cnso of nconitino. This intcnscly poiso!ious nlknloid is tho ncotyl dcrivntirc of bcnznconInc, tho lnttcr substnncc k111g rclntivclp non-tosic. Yct tho introduction of furthor ncctyl groups into tho nconitino molcculo docs not incrcnso, but diminishes, its toxicity.
Considering syntliotic drugs from tho point of view of tlicir innnufnctiiro, \vo find t h a t in vory mnny of tlicni alcoliol is ncccssnry, cithcr ns I L solront or ns n rcscting constitucnt-e.g., ndrilin, anresthcsin, plicnnzonc, clilornl, vcronnl, sulpliontil, urotbnno, phenncctinc, nnd mnny others.

Tlic us0 of duty-frco alcohol without iinduly Iinrnssing rcstrictions is cwcntinl for tho cstnl~lislimcnt of this branch of mrinufacturo,. with whicli goes progress in tho discovery and introduction of n c i ~ siibstaiices into nicdicino; but i t i3 3 widcr qucstion still, for this class of manufncturo is onc brnnch of tho fino clicmicnl industry whicli must bo considcrcd as n wholc. Tlic importnnco to tho country of estnblishing upon n firm basis tho fino chcmicnl industry, in wl~ich prorious to August, 1914, Gcrninny stood siiprcmo, has bccn argued 60 freqncntly nnd so convincingly during tho pnst six p a r s t1i:it furthcr rcfcrcnco to i t oiight t o bo unncccssnry, pot un11:i~pily this is not tho cnso.
