|  | Netherby Hypocaust 
 Draught of an ancient Roman Sweating-Stove.
 Mr URBAN,
 I Send you inclosed the draught of an Hypocaustum, or Bath,  
discover'd at Netherby, 10 miles north from  
Carlisle. You may compare it with another at  
Cast-steeds communicated to you (See Vol. xi.  
p.650, Vol. xii p.30, 31, and  
Vol. xvii. p..60.
 The rooms mark'd c were the sudatories, or sweating  
places, where the people retired after bathing. a, a  
were for exercise, &c. That mark'd f, a bath for  
ablution; a necessary part of the Heathen theology in the  
worship of Fortune, to whom the altar is conecrated, which  
is also in another part of your Magazines (See Vol.  
X. p.171.) The communicating funnels (b)  
supply'd the fire with fresh pabulum of air, and at the same 
time the pipes (d) heated the sudatories.
 G. SMITH.
 
 
    
 N.B. Most of the rooms were floor'd with a small  
thick flag, laid in cement, with three courses of pavement  
below.
