but in every other situation where many persons are em- 

 ployed in common workrooms.' 



The following is the report alluded to : 



' I. All the casements of the windows and the three large 

 western doors of the cotton-mills should be left open every 

 night ; the same regulations should take place during the 

 recess from work at noon ; and as many casements should 

 be kept open in the hours of labour as may be compatible 

 with carrying on the operations of the machinery. 



' II. The casements are too small, being in dimension 

 only one-sixth part of the window. They are likewise 

 placed high, and parallel to each other, a position obviously 

 unfavourable to complete ventilation, for the inlet of the air 

 ought to be lower than the outlet. 



4 III. Several fireplaces with open chimneys should be 

 erected at proper distances in each workroom. The stoves 

 now employed afford no sufficient passage for the offensive 

 vapours generated in the rooms, and increase the contamina- 

 tion of the air by the effluvia which they emit. Turf would 

 be the cheapest, and also a very salutary fuel, for it consists 

 chiefly of the roots of vegetables, and yields in burning a 

 strong, penetrating, and pungent smoke, which is likely to 

 prove as good an antidote to contagion as that of wood is 

 found to be by long experience. 



' IV. The rooms should be daily swept, and the floors 

 washed at least once every week with strong lime water, or 

 with water strongly impregnated with the spirit of vitriol, 

 or the acid of tar. The walls and ceilings may be scraped 

 and whitewashed at first every month, and afterwards twice 

 yearly. Lime fresh burnt and as soon as it is slaked must be 

 used for this purpose, and the wash laid on whilst it is hot.
