5. A Monograph of the British Lichens. Catalogue of the 

 Species in the Department of Botan;/, British Museum. Part 

 II, by Annie Loukain Smith. Pp. 400, 59 plates. London, 

 1911. — Part I of the Monograph of the British Lichens, by Rev. 

 James Crombie, was published a number of years ago, but the 

 continuation of the work which he had undertaken was inter- 

 rupted by his illness and death. Part II has now been brought 

 to completion by Miss A. L. Smith. The descriptive text is 

 accompanied by fifty-nine plates, showing the details of structure 

 of the different species. 



IV. Miscellaneous Scientific Intelligence. 



1. Report of the Superintendent of the Coast and Geodetic 

 Survey, O. H. Tittmann, showing the Progress of the Work from 

 July 1, 1909, to June SO, 1910. Pp. 454 ; 34 maps and* 9 in 

 pocket. Washington, 1911. — The annual volume of the Coast 

 and Geodetic Survey opens with an account of the year's work by 

 the Superintendent. The extended domain of the country, par- 

 ticularly in the far East, has increased very much the work to be 

 done. It is noted, for example, that the triangulation for the 

 year covered some 24,000 square miles in the Philippines, while 

 the hydrographic work extended over 9,385 square miles; the 

 topographic survey covered 1,708 square miles, and extended over 

 1,037 miles of coast line, or 10 per cent of the estimated mileage 

 for the islands as a whole. 



Among the Appendixes which accompany the report is one by 

 R. L. Paris on the magnetic observations. Four magnetic 

 observatories have been in continuous operation, namely : at 

 Cheltenham, Md., Sitka, Honolulu, and on Vieques Island, P. R. ; 

 the fifth observatory at Baldwin, Kansas, was discontinued in 

 October, 1909, and the instruments transferred to Tucson, Ari- 

 zona. Appendix V contains the second part of the triangulation 

 in California by C. R. Duvall and A. L. Baldwin. This occupies 

 a considerable part of the volume, and is accompanied by a 

 series of forty charts. 



2. Directions for Magnetic Measurements ; by Daniel L. 

 Hazard. Pp. 131 ; 12 tables, 10 figures. IT. S. Coast and Geo- 

 detic Survey. O. H. Tittmann, Superintendent. — This Bulletin 

 is prepared with the object of presenting in sufficient detail for 

 the use of observers the methods employed by the Government 

 in magnetic observations, and the use of the instruments involved. 

 The Survey has been developed recently by the establishment of 

 five permanent magnetic observatories, and also by the inaugura- 

 tion of magnetic observations on vessels at sea. The methods 

 called for in these two classes of observations, therefore, require 

 the special method of explanation here given. 



The same author has also presented in a quarto publication 

 of the Survey (pp. 94, 23 figures) the results of observations
