SCHOOLROOM VENTILATION. 395 



not found in a single one of the public-school edifices of the great 

 metropolitan city of New York a complete ventilating equip- 

 ment, and by the 15th of that month there was but one such.* 



Prof. Gilbert B. Morrison, in his book. The Ventilation and 

 Warming of School Buildings, says that 



The invariable verdict of all investigators of public school ventilation may be 

 epitomized as bad, had^ bad ! Some are better than others or rather some are 

 not so bad as others but the difference is rather in degree than in kind.t 



In a letter to the writer, so late as last February, the same 

 author says : 



I know of no building in America which is properly warmed and venti- 

 lated. ... I fear it will be many years before the principle of proper ventilation 

 will be put into practical application. 



That the writer " speaks by the book " in his relation of the 



incident at L would be plain to any one who should care to 



read the printed report of the school committee of that city. The 

 opponents of adequate ventilation might possibly have carried 

 their point but for the weighty advocacy of the system ulti- 

 mately adopted by one who is the acknowledged Nestor of the 



medical faculty of L . Of Dr. P 's pregnant address on 



the occasion of the dedication of the edifice, the space at our dis- 

 posal permits but a few brief extracts : 



The movement of which I have spoken has not been fully understood or ap- 

 preciated by the public ; but the time can not be far distant when all will recog- 

 nize its merits; when even those who now deride will join in the general ap- 

 proval, and perhaps, as a means of obtaining popular favor, coolly assert that 

 they themselves were chiefly instrumental in securing its triumph. 



In the fact that provision has been made for physical exercise we may see 

 another proof that a change is taking place in our ideas concerning the proper 

 scope of school training. Formerly such training was that of the mind alone, 

 bodily conditions being to a large extent ignored. Now the doctrine is gener- 

 ally accepted that, for the purposes of education, the individual is to be regarded 

 not as a dual personality body and mind but as a unit; complex, indeed, but 

 still a unit ; and that the aim of the educator should be to produce a complete and 

 healthy development of all parts. 



In the system now adopted 



The amount of fresh air which can be supplied, if desired, is three thousand 

 cubic feet, or more, per hour, for each occupant of the building. This, accord- 

 ing to the estimate of very careful observers, is sufficient to keep the air of the 

 rooms pure. By this device we become independent of the weather, and can
