t> ART II.] I^E arson : Antiseptic Treatment of Timber. 73 
nemn, and Jodelite were made with Atlas . In these experiments hot 
coal-tar was not applied to the timber after being treated with Atlas, 
as directed in the prospectus, for had that been done no estimate could 
have been made as to the value of the solution as compared with 
other preservatives. 
In the experiments above mentioned a 20 per cent, solution was 
taken, and the time of immersion was 24 hours, while the species of 
timber treated were the same as those chosen for the experiments cairied 
out with other antiseptic solutions. The quantity of the solution absoib- 
ed by the different timbers is shown in the following table :
