EEPOET OF THE SECRETARY. 29 



given in the first edition there have been added instructions for noting 

 periodical phenomena, earthquakes, auroras, &c.,and special remarks 

 suggested by the experience of previous years. This publication forms 

 an octavo pamphlet of seventy pages, and is now, perhaps, the most 

 convenient and complete work for the purpose to be found in the 

 English language. 



The catalogue of the Dipterous Insects of North America, prepared 

 by Baron Ostensacken, described in the last Report, has been published. 

 It forms an octavo pamphlet of ninety-two pages, and constitutes a 

 portion of a series of works which will be alluded to in a subsequent 

 part of this Report. 



11. It was mentioned in the last Report that the Institution had 

 subscribed for a few copies of a treatise on the Fossils of South Carolina, 

 which was commenced by Professors Tuomey and F. S. Holmes, and, 

 after the death of the former, continued by the latter. Copies of five 

 parts of the continuation have been received, and will be distributed 

 in exchange for other works of foreign authors of the same class. This 

 work has been patronized by the State, and is alike creditable to the 

 industry, talents, and knowledge of the author, the skill of the artist, 

 and the intelligent liberality of the government of South Carolina. 



Another publication to which a subscription has been made is Peirce's 

 Analytic Mechanics. This is not an elementary compilation, but 

 consists principally of original solutions of many of the most important 

 problems of theoretical astronomy and pure physics. The author at 

 first offered to present this work as a series of memoirs to the Insti- 

 tution, but by means of the subscriptions which have been obtained 

 for it, the publication has since been undertaken by private enter- 

 prise. The copies subscribed for by the Institution will be distributed 

 to some of the first class learned societies in Europe^ and will doubt- 

 less be regarded as an important contribution of new truths, as well as 

 of methods of establishing some of those which have been previously 

 discovered, alike indicative of the genius of the author and of the en- 

 lightened and liberal appreciation of the country. 



A subscription has also been made for a number of copies, for foreign 

 distribution, of the Mathematical Monthly, edited by J. D. Runkle, of 

 Cambridge, a journal intended to promote the study of mathematics 

 in this country. The plan and execution of this work are such as to 

 commend it to all who are interested in the advance of the important 

 branch of knowledge to which it pertains; and it is gratifying to learn 

 that the patronage which it has received, as well as the number and
