TREE DISINFECTANTS. 

 At the present time bichloride of 

 mercury dissolved in either wood al- 

 cohol or water, is the only disinfectant 

 recommended and used by the Davey 

 Tree Expert Co. for the treatment of 

 tree wounds to kill any fungus which 

 may be present. Bichloride of mercury 

 is known also as mercuric chloride or 

 as corrosive sublimate. It is manufac- 

 tured by heating a mixture of mercu- 

 ric sulfate and common salt. 



Bichloride of mercury is procured 

 from druggists in the form of small 

 tablets. These tablets contain not 

 only bichloride of mercury but also 

 sodium chloride which is common salt. 

 Ordinarily bichloride of mercury is 

 only moderately soluble and the solu- 

 tion is slightly acid. However, by add- 

 ing salt, as in the commercial tablets, 

 the solubility is greatly increased and 

 the acid is neutralized. Also the addi- 

 tion of salt lessens to a certain extent 

 the activity of the compound. 



Many times questions have been 

 asked concerning the solubility of 

 mercuric chloride not only in water 

 but also in alcohol. At ordinary tem- 

 perature, 100 parts of water will dis- 

 solve 7 to 8 parts of mercuric chloride. 

 It is more soluble in alcohol. Since 

 the formula for tree wound disinfect- 

 ing calls for only one part in 1000 

 parts of water or alcohol mercuric 



chloride is easily soluble enough for a 

 tree surgeon's purpose. Two large 

 tablets in one quart of water or alco- 

 hol are amply sufficient. 



It is a well known fact that bichlo- 

 ride of mercury is very poisonous. 

 The poisoning property is due to the 

 fact that it combines directly with a 

 number of substances and particularly 

 with albumin which forms a part of 

 living matter. 



Mercury either in the pure state or 

 in solution such as the solution made 

 by dissolving its bichloride in water 

 has the peculiar property of dissolving 

 most metals to form a substance 

 known as an amalgam. Tin and cop- 

 per are very readily dissolved while 

 iron and platinum dissolve only slight- 

 ly if at all. When an amalgam is 

 formed the mercury is removed from 

 its solution, and consequently its value 

 as a disinfectant is destroyed. There- 

 fore, it is necessary to always keep 

 the solution in some glass or earthen- 

 ware container. It is quite probable 

 that by using a sprayer with a glass 

 container little damage to the solu- 

 tion would result from it passing 

 through a tin or galvanized iron noz- 

 zle.
