15, Micr. = 5".69 has been used instead of 5.31, on the assumption that the comple- 

 mentary decimal was inadvertently read off from the micrometer head. 

 This gives At5=llr.57J. 

 29, for 2A. 8m. 7*. 74, read &h. 8m. 7.74. 



4, The AC! 21r.29 seems to have been accidentally written instead of 22r.29, and this hypo- 

 thesis was evidently made in taking the printed mean, although the original MS. gives 

 the micrometer-reading as printed. This assumption of an error of Ir. has been mado 

 in the computation, and the printed mean therefore employed. 

 for 22. 11 read 22.01. 

 Ad should be positive. 

 for Feb. 12 read Feb. 13. 

 " 1.18 " 7.18. 

 " 0.78J " 0.79J.
