SIZE MADE OF POTATOES. 



One of the beneficial ufes of potatoes, not perhaps ge- 

 nerally known, is, that the ftarch of them, quite frefli, and 

 wartied only once, may be employed to make fize, which, 

 mixed with chalk, and diluted in a little water, forms a veiy 

 beautiful and good white for ceilings. This fize has no 

 fmell ; while animal fize, which putrefies fo readiiv, always 

 exhales a very difagreeable odour. That of potatoes, as it 

 is very little fubje£l to putrefaclion, ap[)ears from experience 

 to be more durable in tenacity and whitenefs ; and for white- 

 wafliing fliould be preferred to animal fize, the decompofi-

 halations.
