CIRCULAR. 



Capt. C. jM. Scammon, of the U. S. Revenue Marine^ having for many years been engaged in 

 investigating the Cetacea and other Marine Mammals of the Pacific Coast of America, and having 

 accumulated a large store 6( facts, many of which are believed to be entirely new, and having also 

 made numerous careful and detailed drawings and measurements of these animals, proposes shortly 

 to publish a volume in which these results will be given. Some of the material which has been 

 obtained with so much labor and expense, has been already before the reader in the pages of the 

 ''Overland Monthly," and also through the Smithsonian Institution at Washington, D. C, and the 

 favor with which this has been received by scientific men and by the public, has given encourage- 

 ment to the idea of bringing this material together in a permanent form. He has also been 

 encouraged by the high praise bestowed upon his work by the eminent Zoologist, Prof Baird, 

 Assistant Secretary of the Smithsonian Institution, as well as by that of Prof. Whitney, the State 

 Geologist of California, and Prof. Davidson, of the U. S. Coast Survey. 



The volume which it is proposed to issue will be in large quarto form, elegantly printed, and 

 illustrated with thirty or more fine full-page plates, exhibiting the forms, habits, and peculiarities of 

 the whales, seals, etc., of the Pacific Ocean, and showing also the various weapons used, both by 

 civilized whalers and the savage natives, in the capture and destruction of the animals. 



The price of the work — which is to be handsomelj- bound in cloth — will be Five Dollars to 



Subscribers.

TESTIMONIALS. 



[Letter from Prof. Baird. of the Smithsonian Institution, Washington, D. C. ] 



Washington (D. C), June 1st, 1872. 

 Mv DEAR Sir : 



I am much pleased to hear that you intend reproducing your various 

 notes upon the Cetacean and otht-r IMarine Mammals of the Pacific Coast in 

 a systematic book form, to be accomi^auied by the Illustrations which inter- 

 ested me so much when I saw them in your Note Book. In the previous 

 paucity of reliable information in regard to Marine Mammals on the Pacific 

 Coast of Xorth America, the appearance of your first Memoir upon the "NMiales 

 marked an era in their history, and your descriptions and figures have already 

 been translated into the German language and published in Europe. 



In the great economical importance of the animals in question, and the 

 extent to which they add to the productive resources of our country, it is of 

 great moment that they should be properly described, while naturalists will 

 find in your work the means of settling a great many doubtful questions. 



I tnist, therefore, that you will feel inclined to carry out your plan, and 

 that before long we may welcome a book which, I am sure, will make its mark. 

 Few persons have had better opportunities of studying this subject than have 

 fallen to yuur lot, while I am sorry to say that I scarcely know of another 

 who has used his opportunities in so satisfactory a manner in the cause of 

 Science. Very truly yours, 



SPENCER F. BAIRD.

To Capt. C. M. Scammon. 



Mv DEAR Sir ; 

 I learn with much pleasiire that yon are making arrangements for the 

 publication cf the results of the investigations which you have been making 



for many years, with so much skill and patience, into the habits and distri- 

 bution of the Cetacea of the Pacific Coast of North America and the Arctic 

 Seas. Having been long familiar with your mode of work, and having had the 

 pleasure of examining, from time to time, the materials you have collected, 

 I feel biire that your results will be of great value, and that they will deeply 

 interest the commercial as well as the scientific world. Your volume will 

 command attention not only on this Coast, but on the Atlantic side of the 

 Continent, as well as in Europe. The proofs of the Illustrations which I have 

 seen are excellent, and they will add greatly to the value of your volume. 

 Wishing you all success in your undertaking, 



I remain, very sincerely, yours, 



J. D. WHITNEY.

[Letter from Prof. D.widson. Asst. U. S. Coast Survey, in charge Pacific Coast.] 



My de-\e Captain : 



San Fe.\ncisco, Cax., June 20th, 1872. 



I have examined with interest and gi-atificatiou your original Dramngs, 

 and the specimen Engraving thereof, to illustrate your proposed work on the 

 Cetacea. 



Your lung study and practical acquaintance with the Whale and its con- 

 geners throughout the Pacific, make you authority upon the subject. 



In our frequent conversations upon the "Wliale, I have repeatedly urged 

 you to this step ; and now that you are launched upon it, command my hearty 

 assistance in every way. 



Yours, very sincerely, 



GEORGE DAVIDSON.
