a constant war against regulators they conclude 

 that they need one. That they did put their foot 

 into a puzzling contrivance will be evident when 

 you observe that in a later edition of catalogue No.

 twenty gallons of water.) Methods consisting of 

 electricity, mercury, water-expansion, lamp-trips, 

 and numerous other devices, we have practically 

 tested. {Can we believe that they had tested the 

 regulator which they now claim to have adopted, 

 when they did not have one on their incubator at 

 World' s Fair, during the latter part of which they 

 announced that they had a regulator, after examin-

 and asking where and by whom they were made. 

 Did they have it on the two incubators outside the

 but find nothing so complete in every particular as 

 the late improved combined thermostat, which is 

 as sensitive to the heat's action as the thermometer 

 itself. {How does that sound after what they said in 

 the first act about self-regulating incubators? A 

 month or so previous they were no good ; now there
