2 INTRODUCTORY 



laboratories, British or foreign, approved by the licensing body 

 granting the diploma, in which chemistry, bacteriology, and the 

 pathology of the diseases of animals transmissible to man are 

 taught. 



Note . The laboratory instruction shall cover a period of not less 

 than four calendar months, and the candidate shall produce 

 evidence that he has worked in the laboratory for at least 240 hours, 

 of which not more than one-half shall be devoted to practical 

 chemistry. The laboratory course should be so arranged as to lay 

 special stress on work which bears most directly on the duties of 

 a medical officer of health. 



The amendments in this rule reduce the number of 

 months of instruction from six to four, and define the 

 hours worked as 240, of which at least 120 shall be devoted 

 to Bacteriology. The net result is that students will 

 thus require to do as a minimum 15 hours' practical 

 laboratory work per week for four months. Many students 

 will find it more convenient to do 12 hours per week for 

 a so-called six months' term of 20 weeks. 



The final clause of the rule, namely, " The laboratory 

 course should be so arranged as to lay special stress 

 on work which bears most directly on the duties of 

 a medical officer of health " might usefully have been 

 made more specific, and been extended to include the 

 phrase, " and the Examiners for the Diploma shall have 

 special regard to this recommendation." 



The student will be well advised to exceed the minimum 

 periods above laid down, as tar as he can, and more espe- 

 cially if he is not already well informed in the subjects of 

 chemistry and bacteriology. 



The scope of the work and the methods may be thus 

 summarized on the basis of the Syllabus of the Scottish 

 Conjoint Board : 



DIPLOMA IN PUBLIC HEALTH. 

 PUBLIC HEALTH LABORATORY WORK COURSE 

 comprises : 



Physical, Chemical, and Bacteriological Examination of 

 water, sewage and sewage effluents, air and other gases, 

 food stuffs, beverages, soils, and building materials. 

 Examination of disinfectants, antiseptics, deodorants.
