From the above results It seems thatthe percent variation decreases with an increase Intemperature. These percentages do not show the regu-lation to be very constant but by employing a moredelicate relay and a thermal-strip made up of thinstrips the sensitiveness of the device could be in-creased almost to any desired degree. For thecrudeness of the equipment employed these results aremuch better than was expected. It may be here statedthat tho the field for electrical thermostats be abarren one, from a practical point of view, by the ob-taining of such satisfactory results with the abovecrude arrangement, these results ought su
