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

 mentary decimal wag inadvertently read off from the micrometer head. 

 This gives A<! = llr.57J. 

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



4, The A.5 21r.29 seems to hare been accidentally written instead of 22r.29, and this hypo- 

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

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

 in the computation, and the printed mean therefore employed. 

 for 22.11 read 22.01. 

 &t should be positive. 

 for Feb. 12 read Feb. 13.
