102 A GREAT PROFESSION OP THE FUTURE. 



intention of resting content with this most encouraging 

 success, but proposes to avail himself of his professional 

 influence and admirably-organized business to extend his 

 sphere of sanitary work. He is making arrangements to 

 deal with the more general and complete sanitation of 

 dwellings, and drainage of towns on improved lines. The 

 question of regulating the temperature of air in buildings 

 is one of great importance to health, and, at the urgent 

 request of architects, he is now engaged in the preparation 

 of a scheme for efficiently combining heating and ventilation 

 in a scientific and practical form, which will insure greater 

 economy and, by the application of heat to the proper parts 

 of the building, effectually prevent the cold draughts which 

 are experienced in most public edifices. The chilling 

 currents which have a deadly effect on delicate people are 

 chiefly caused by the defective methods of heating at present 

 in use. Mr. Boyle's plan will save architects the trouble 

 and inconvenience of calling in a separate firm to do the 

 heating, and better results must necessarily follow from 

 the harmony and comprehensiveness of the arrangements. 

 We may safely predict in this department a most extensive 

 and profitable business. Ventilating and sanitary engineer- 

 ing is now only in its infancy, but it is undoubtedly 

 destined to become one of the most important professions. 

 Mr. Boyle has recently invented an ingenious system of
