SELECT WORKS ON SCIENCE PUBLISHED DURING 1878. 



The following enumeration continues the record of the 

 principal works published in the various departments of 

 science from the previous Annuals, and has been compiled 

 in accordance with the same principles. In other words, it 

 is necessarily a very partial enumeration, being, for the most 

 part, confined to those works that have been noticed in sev- 

 eral of the most prominent and widely circulated periodicals 

 of the day; for the limitations of the Record preclude an 

 exhaustive bibliography. The ground in this respect is cov- 

 ered by elaborate bibliographies, the chief of which are enu- 

 merated under the head of "Annual Records of Progress in 

 Science." Those volumes that have features of general in- 

 terest to commend them, or are of special scientific value, 

 have, for the most part, been included. A few, however, of 

 an exceptionally bad character are noticed with a word of 

 caution. 



Whenever the volumes catalogued could be referred to 

 without excessive loss of time or expense, they have been 

 consulted, and the titles taken, or corrected directly from 

 them. Unfortunately, this means of verification or correc- 

 tion could only be employed to a limited extent. The at- 

 tempt to do so, nevertheless, has cost an amount of time and 

 labor scarcely repaid by the results. 



The works in question are enumerated as nearly as pos- 

 sible, or as seemed convenient to the reader, in a logical se- 

 quence, and under those headings to which it was supposed 

 the majority of persons would look for works of the charac- 

 ter desired. As to the periodicals, comparatively few could 

 be catalogued, and these mostly (l) the publications of very 

 prominent societies and magazines of a high character, or 

 (2) the publications noticed in the Annuals to which refer- 

 ences have been made for notices. All the periodicals have 

 been enumerated under the head of " General Science ;" but 

 in the case of those devoted to special branches, references 

 have been made to the places where they are catalogued,
