or man. Its evolution has been the result of much study and 

 experiment to furnish an effective, yet inexpensive and convenient 

 means for producing the desired result. It consists of only three 

 parts, viz. : A combined base, lamp, cup and handle ; a lamp 

 burner ; and a combined concentrating cylinder and evaporating 

 pan. Wood alcohol is used to generate heat in it, one cent's 

 worth of which will evaporate two fluid ounces of the preparation 

 used. The peculiar form of this apparatus allows of a quick and 

 convenient filling of the lamp cup, concentrates and centers the 

 the flame on the bottom of the evaporating pan, and prevents 

 waste of heat from side drafts. Such air as is needed for com- 

 bustion, and no more, is drawn up and around the lamp cup, 

 keeping it cool A ridge around the base catches any accidental 

 overflow of the fluids used. The peculiar manner of connecting 

 the handle with the base of the appara'us keeps it cool for hand- 

 ling. The tall cylinder concentrates and conserves the heat and 

 allows of its being handled by its lower and cool part. Ordinary 

 candle wick or a rolled kerosene lamp wick is used in the burrer. 

 All the parts are very durable, being made of cast iron, galvanized 

 iron and copper. It will last a lifetime. A number can be 

 carried by their handles in each hand and quickly distributed 

 and operated in any greenhouse, dwelling or apartment. 



This apparatus is not a toy. It is constructed for 

 practical work. Being inexp.^nsive, a number can be con- 

 venitntly operated and thus an effective and abundant supply of 

 the vapor or gas used can be quickly generated wherever needed ; 

 be that in closets, corners or open spaces. 



Physicians will find this apparatus invaluable for disin- 

 fecting their clothing in a closet or small room after visiting 

 contagious cases. It will economically and quickly evaporize 

 formaldehyde or any other disinfectant. This fumigator will be 

 found the most effective apparatus for disinfecting dwellings
