Status of Chemists. — In a circular recently issued 

 in cunneclion with recruiting in Great Britain hve classes of 

 men were referred to : {a) navvies, tunnellers, and chemists ; 

 {b) skilled workmen, such as artisans, etc.; (c) St. John's 

 Ambulance men, etc. ; {d ) pharmacists and other specialists 

 for the R.A.M.G. ; (c) men who are not eligible for infantry, 

 but suitably for Departmental Corps, A.S.C., R.A.Al.C., etc. 

 It was stated that "men of the classes [a] and (b) will, if tbey 

 pass the the necessary trade tests, be finally approved of for 

 ti._Mi respective corps." Sir William Ramsay thereupon made 

 the following comments in the Movnuig Post : — " It will be 

 noticed that the classes are arranged according to rank, and that 

 chemists are included in the lowest classes. It is charitable to 

 su])pose that this has been done in sheer ignorance ; but is it 

 not time that men of such gross incapacity as the framer of 

 this leaflet should no longer have any voice in national afifairs? 

 This is no isolated instance. My experience has shown me 

 during many years that Government officials, from the Ministers 

 to the subordinates, are disgracefully ignorant, not merely of 

 the nature of the work done by chemists, but also of their pro- 

 fessional and social standing."
