 cautions have been taken whic4i are of a considerable 

 importance. In the first place on each side we have a 

 gutter to caiTy off the water that has fallen from the

 The plan of ventilation consists in having at the bottom 

 a certain number of sticks; perpendicular to these, 

 others are placed, which enable the gases to make their

 of notice, is to have a gutter at the bottom where the 

 water resulting from the evaporation can collect.
