88 VISIT OF SIR CHARLES DILKE. 



the approval and sanction of the Local Government Board. 

 The work was completed in April last, and is pronounced 

 to be the most unique and successful example of ventilation 

 in this country. 



Her Majesty's Chief Inspector of Hospitals, after repeated 

 experiments, has expressed his entire satisfaction with it; 

 and the results of the tests instituted and carried out by 

 the Asylums Board, show that the air in the different wards 

 is entirely changed every five minutes without the slightest 

 draught or inconvenience being experienced. The Air 

 Pump Ventilators, as tested with the anemometer, were 

 found to be extracting five million cubic feet of air per 

 hour. Sir Charles Dilke and other members of the Royal 

 Commission on the Dwellings of the Poor, and a large number 

 of representative gentlemen, interested in these matters have 

 examined with keen interest the arrangements on the 

 Castalia, and have expressed their entire approval. The 

 work was executed under a special guarantee of success, 

 and the fact that payment of the account was made 

 immediately after the tests were completed sufficiently 

 proves the satisfaction of the Board with Mr. Boyle's 

 system as applied to the Castalia. Full particulars and 

 drawings of this hospital ship, showing how the system of 

 ventilation is applied, may be found in the June numbers
