 value and the correctness of the principles upon which it was 



designed, and being satisfied with the merit of the invention 

 he lost no time in submitting it to the notice of the 

 executive committees of several Government departments, 

 who received it most favourably. To these introductions by 

 Captain Galton, Messrs. Boyle have reason to express them- 

 selves considerably indebted, for the ventilators are now 

 extensively used by all the departments. 



The example encouraged influential men to give the 

 subject of ventilation their attention, and thus we may give 

 Captain Galton a prominent place among the pioneers of 

 this important sanitary reform. Another good friend to 

 the cause was the late Sir Randall Martin, chairman of one 

 of the committees in the War Department, who took not 

 only a great liking to the invention but to the inventor, to 

 whom he accorded his warmest friendship. 



A description of the various sanitary inventions of Mr. 

 Boyle and his son is to be found in the excellent books on 

 ventilation, sanitation, and heating, written by Capt. Galton. 

 The inventions are also described in over fifty different 

 \\..iks; indeed, we do not know any modern book treating

Our churches are still so badly ventilated that congrega-
