Prom the above statements it will be seen that all the treated speci¬ 
mens are in good order, while of the untreated pieces it has been found 
necessary to remove no less than five, three others are under process of 
destruction and four are sound. The period during which the solution 
has been under trial barely exceeds one year; on the other hand, the 
treated timbers have successfully withstood two heavy periods of rain 
amounting to over 100 inches in each yeai. 
Plate No. VII illustrates the state of treated and untreated specimens 
of a and b Boswellia serrata and c and d Odina Wodier after
