V^. COULOMB read in the Inftitute on the 26th of May, 

 a curious memoir on the refirtance of fluids when the move- 

 ment is exceedingly (low, and he has found that it is then 

 merely as the velocity, inftead of being as the fquare of the 

 velocity. For his experiments he employed the force of tor- 

 fion, of which he firft formed an idea. He complains that 

 Mr. Cavendiih, in the Philofophicai Tranfa6trons for laft 

 year, afcribes this invention to an Englifliman who never 

 publiflied anv thing on the fubjeft.

The obfervations of the Arabs in the tenth century are 

 extremely valuable. We were acquainted with only three, 

 when I difcovered among the manufcripts of my former 

 mafler, Jofeph Delifle, an Arabic copy of a part of the work 

 of Ibn lunis, where there arc a great many. But the ori- 

 ginal was at Leyden ; and we have long folicitod the Bata- 

 vian government to intruft us with it. At length, on the 

 a6th of May, our ambaflador brought to the Inftitute this 

 valuable manufcript, containing 400 pages in quarto fmall 

 chara6\ers ; and we hope that not only a translation of it will 

 be printed, but that part alfo of the Arabic original which 

 is interefting to aftronomy. C. Chauffin has already tranf- 

 lated that which I procured for him.
