 — 182". 75 by — 182". 79 and an analogous niodilicatioii is re(|üire(l 

 in the tables I, II and IX. 



Instead of the values which relate to — 182°. 75 of table II we 

 now icet : 



TABLE II. Values for — 183^ instead of those of table 11 of Comm. N". 91c. 



The agreement is thereby greatly improved, as O.-C.jy is changed 

 from — 0.029 to — 0.008.' 



In the tables YIII of Comm. N". 95" and IX of Comm. N°. 95/ 

 the three temperatures — 183° from which a mean has been derived, 

 are all diminished by 0°.04. O.-C. thereby becomes less by 0.0008 

 and the agreement improves in the same rate. 



As to the determination of Jnly 6, '06 the moditication is very 

 small. 



In the tables VIII of Comm. N". 95« and IX of Comm. N". 95/" 

 no change occurs if we omit this last determination in the mean, 

 in tables I and II it is not nsed. 



With regai'd to this and to what has been said in note 1 of § 13 

 of Comm. N". 95'^, no new calculation has been made. 



As a supplement to colunms 2 and 3 of table I towards a complete 

 calibration of Fti' we can use Ptj in table V of Comm. N". 99'Mvith
