It is assumed that the pharmacist has had the necessary training to under- 

 take the microscopical examination of the substances above classified, with 

 the aid of such standard works of reference as may be required. The 

 micro-analyses should also include: 



1. Gross and net weight determination of all samples that require it, 

 for which purpose an accurate balance is necessary. 



2. Moisture determinations of such substances as may require it. There 

 should be no difficulty in constructing the necessary apparatus for making 

 moisture determinations. 



3. Ash determinations of substances which require it. This calls for 

 a special equipment including a platinum dish, ignition furnace with burners, 

 etc. 



4. Use of special tests, as sublimation tests for benzoic acid and salicylic 

 acid, the hand wheat gluten test, Bamihl gluten test, Grahe's cinchona test, 

 color reaction tests for boric acid, salicylic acid, morphine, and opium; 

 tests for phytosterol and cholesterol crystals, etc., etc. These and odier tests 

 are explained in the several reference works cited above. In the examina- 

 tion of liquids or semi-liquids as wines, beers, cider, vinegar, mUk, cream, 

 sewage, extracts, tinctures, etc., a centrifuge is desirable. 



E. Bacteriological Work. — The pharmacist should be prepared to do the 

 following work in the bacteriological laboratory. 



a. Prepare culture media for use of physicians, as may be required. 



b. Prepare sterile throat swabs for the use of physicians. 



c. Prepare stains and do staining for physicians, as may be required. 



d. Make bacteriological determinations of milk, jams, jellies, impure 

 drinking water, vinegar, wine, sera, vaccines, antitoxins, contaminated foods 

 and drinks, sewage, etc. 



e. Sterilize pharmaceuticals, surgical supplies, etc. 



f . Assist the physician in opsonic work, as may be arranged or agreed 

 upon. 



g. Do bacterial culture incubation work for the physician, make sub- 

 cultures, Wassermann reaction for syphilis, etc. 



h. Filter and sterilize drinking water to be supplied to customers. 

 The above outline is intended as a suggestion only. Experience and 

 opportunity will determine what can actually be done.
