 FIRST GROUP. 

 COOLING, LIGHTING, ETC. 



Of the twenty-five articles referred to us, we judge eleven to be 

 worthy of much praise. 



But few refrigerators are shqwu. The "Zero,'.' No. 582 (A. M. 

 Lesley), is the best. We esteem it the best we know, not so much 

 by possessing novel features of great merit, as by being an extremely 

 well devised, efiective and economical construction. The princi- 

 ples it involves are long tested and approved. It preserves the 

 meats and vegetables at a low temperature, with the consumption 

 of less ice than any other known t^ us. 



The Ventilating and Air Purifying Device, No. 584 (A. S. 

 Lyman), seems to us entitled to attention. Air is passed through 

 charcoal and other purifying agencies by the increased gravity due 

 to its being cooled with ice, and it is finally poured in an extremely 

 delicate current on the head of the patient in bed. The motion 

 is perceptible only by delicate tests, and we believe the effect of 

 this apparatus may in many cases, turn the scale of life or death. 

 It is the best article exhibited relating to ventilation. 



B. J. Burnett's Ventilators, No. 869: This system of ventilation 

 is represented by five models — a combination ventilator, using con- 

 cealed pipeages to and from each apartment; combined lights and 

 ventilators for ships, forming triple transverse supports to the glass 

 against the pressure of the sea, with rubber jDacking; sk3'-light 

 ventilator for houses, where the hall- way "extends uninterruptedly 

 to the roof; a ventilator for churches, giving pure air in any area 

 through what the patentee calls a " diffusing hood;" and the hexa- 

 gon ventilator, harmonizing with a florid style of architecture. 

 Mr. Burnett deseiwes much credit for his successful labors in this 

 all important department of practical science. His ventilators 

 develop an economical phase, seeing that by their adoption, 'cock 

 lofts and upper sleeping apartments of a house may be rendered 

 as comfortable and pleasant as any other portion of the building, 

 both in summer and winter, with unexcelled power of graduating 

 the velocity and amount of circulation. 



No. 786 (J. P. Frink), shows a mode of ventilation in connection 

 with gas lights which has come to be highly approved. 



No. 749 (Tucker Manufacturing Company) includes a splendid 

 collection of chandeliers, made from cast iron, and cheaply bronzed
