The Library of Prof. Da Bois-Reymond. 



The library of the late Prof. Emil Du Bois- 

 Reymond, a coUtction of extraordinaiily high 

 value, is for sale by Gustav Fock, Neumarkt 

 40 and Magazingasse 4, Leipzig, Saxony. It 

 comprises more than fourteen thousand vol- 

 umes and pamphlets, nearly all the books 

 being bound, while the smaller writings are 

 mostly arranged in collecting boxes, partly 

 alphabetically and partly systematically. It 

 contains sets, more or less .complete, of about 

 forty-five scientific journals and transactions 

 of societies of all scientific countries and 

 nearly every scientific work that has been 

 written on physiology, physics, and philos- 

 ophy. Almost every volume bears Prof. 

 Du Bois-Reymond's own signature; and a 

 very large number of the books, especially of 

 his own works, are enriched by additions, 

 memoranda, notices, appendices, and re- 

 marks in his own handwriting of unique 

 value. Prof. Du Bois Raymond's heirs de- 

 sire that the library be kept unseparated; 

 and, to promote this object, will give prefer- 

 ence to bidders who will guarantee preserva- 

 tion as a whole. In the case of duplicates 

 reasonable arrangements will be made for 

 the repurchase by Herr Fock of such vol- 

 umes in that category as may not be wanted. 

 The library, valued at 30,000 marks, or 

 $7,500, is offered for 22,000 marks, or 



$5,500. Cable messages regarding the pur- 

 chase may be sent to the cable address, 

 "Buchfock," Leipzig; " Du Bois," if the 

 proposition is to purchase the complete set 

 on the terms offered ; " Reymond," if a cata- 

 logue is wanted before giving a decision. 



Tides of the Bay of Fnndy The real 



character and height of the famous tides of 

 the Bay of Fundy, as given by Prof. W. M. 

 Davis in Science, from the Canadian Geologi- 

 cal reports, are as follows : " From the mouth 

 of the bay, forty eight miles wide and from 

 seventy to one hundred and ten fathoms deep, 

 the bottom rises at the rate of four feet a 

 mile over a distance of about one hundred 

 and forty-five miles to the head. On the 

 coasts adjacent to the mouth the spring tides 

 vary from twelve to eighteen feet. Within 

 the bay the spring and neap tides are as fol- 

 lows : Digby Keck, 22-18 ; St. John, 2*7-23 ; 

 Petitcodac River, 46-36 ; Cumberland Basin, 

 44-35 ; Noel River in Cobequid Bay, 53-31 ; 

 the last named being the greatest tidal oscil- 

 lation in any part of the bay. The flood tide 

 rises about twenty feet above mean sea level ; 

 the ebb falls the same amount below, leav- 

 ing the branch bays empty or nearly so. The 

 tidal bore is seen in Maccan River, entering 

 Cumberland Basin, but is stronger in Petit- 

 codac River, entering Shepody Bay, At the
