NOTE. It should be noted that this series has hitherto been known as " Self- 

 Instruction for Students in Gas Manufacture." The titles are altered, as the 

 examinations are now held under the name of Gas Engineering, and not Gas 

 Manufacture. " Constructional," however, still appears under the old title. 



SELF-INSTRUCTION FOR STUDENTS IN CAS SUPPLY 



By "MENTOR." 



With Numerous Illustrations. 2 vols., crown 8vo. Price 3s. 6d. net each. 

 The object of these little books is to assist students who are contemplating 

 entering for the Examinations of the City and Guilds of London Institute in 

 the subject of Gas Supply. The subject is treated on the same lines as are 

 adopted in the author's above-mentioned works on Gas Engineering viz., in 

 the form of question and answer, which has been found to be a very useful 

 method of imparting information to those students who are not able to 

 attend classes, or who have not the opportunity of access to technical libraries.
