The above records are satisfactory so far, though the tests have only 
being in progress for a year. The untreated timbers have on the whole 
been damaged to a greater extent than similar pieces put in the ground 
in conjunction with experiments carried out with other antiseptic solu- 
Plate IX, specimens a and b illustrate an untreated and a treated 
pieces of Boswellia serrata timber after being placed upright in the 
ground for four months, and specimens c and d of untreated and treated 
Bombax malabaricum timber after being in the ground for seven weeks. 
Summary. 
This solution differs from other antiseptic fluids of the same 
category, in that it combines colouring matter with antiseptics and is 
therefore more suitable for indoor work. On the other hand, the depth 
to which the solution penetrates when applied with a brush, is not so 
great as in the case of immersion. As regards cost of treatment it 
compares favourably with other similar patent solutions.
