Investigation of the Dry Rot in Timler. 
Ac the Sittings of the Royal Academy of Sciences at Paris, on 
the 16th ult., a Report was read on ‘ An Essay-on the Dry 
Rot, by Robert MacWilliam, Architect: and on the 23d the 
Secretary, Mons. Cuvier, addressed and transmitted to the au- 
thor an acknowledgement of the receipt of the work by the Aca- 
demy, and of the proceedings that had in consequence taken 
place; intimating to him, that it was on account of the impor- 
tance of the objects of which he had treated, and of his scientific 
researches, that the Academy had been led to have the analysis 
(compte verbal) made out ; and adding, that though it was con- 
trary to their usage to deliver to authors a copy of their Reports 
on printed works, the Academy had made an exception in his 
favour, and directed their Secretary to present him with a copy 
of this Report, and to thank him for having made them aequaint- 
ed with a work, the interest and instruction of which were such 
as to induce them to give it an honourable place in the library 
of the Tustitute.
