By LESTER F. WARD. 



Annual address of the President of the Biological 

 Society of Washington delivered Jan. 24, 1891. A 

 historical and critical review of modern scientiflc 

 thought relative to heredity, and especially to the 

 problem of the transmissionof acquired characters. 

 The following are the several heads involved in the 

 discussion Status of the Problem. Lamarckism, 

 Darwinism, Acquired Characters, Theories of He- 

 redity, Views of Mr. Galton, Teachings of Professor 

 Weismann, A Critique of Weismann, ;Neo-Darwin- 

 ism, Neo-Lamarckism, the American "School,"" Ap-

 save at least that amount every other day, directly 

 or indirectly.*" — Chicago Standard.

 who make much use of the mails. The ninety-four 

 pages contain a great amount of information, very 

 well arranged, knowledge of which should prevent 

 most of the delays and losses in the mails." — Boston

 affairs."' It will enable him to settle almost at a 

 glance the points of inquiiT" in postal matters that 

 are constantly arising.'" — New York Home Journal. 



"If all who use the mails (and who does not?) will 

 turn to the pages of this useful little guide, the labor 

 of the postal authorities will be greatly simplified, 

 fewer mistakes will be possible, and the public will 

 be better served. Its simplicity and low cost will 

 commend it to ail. and give it what it deserves, a 

 universal sale."— S'on. liiomas L. James, ex-Post-

PROTECTION FROM LIGHTNING. 



All the capital desired for the parent company 

 to handle my patents on a new method of protect- 

 ing buildings from lightning has been subscribed. 

 Sub-companies and agencies to introduce the 

 invention are forming, and any desirous of tak- 

 ing State-rights should address The American 

 Lightning Protection Co., Sioux City, Iowa. 



The English patent is lor sale, and offers 

 an excellent opportunity for the formation of a 

 company now that the American company is so 

 favorably started.

Nm Method of Protecting Properly 

 from Lightning. 



The Lightning Dispeller. 



Price, $20 to $30.— According to size. 



The Patent Lightning Dispeller is a conduc- 

 tor specially designed to dissipate the energy 

 of a lightning discharge, ^to prevent its 

 doing harm, — placing something in its path 

 upon which its capacity for causing damage 

 may be expended. 



No recorded case of lightning stroke has 

 yet been cited against the principle of the 

 Dispeller. So far as known, the dissipation 

 of a conductor has invariably protected under 

 the conditions employed. 



Correspondence solicited. 



AGENTS WANTED. 



The American Lightning Protection Company,, 



United Bank Building, Sioux City, Iowa. 



QUERY. 



Can any reader of Science cite 

 a case of lightning stroke in. 

 which the dissipation of a small 

 conductor (one-sixteenth of an- 

 inch in diameter, say,) has failed 

 to protect between two horizon- 

 tal planes passing through its- 

 upper and lower ends respective- 

 ly? Plenty of cases have been 

 found which show that when the 

 conductor is dissipated the build- 

 ing is not injured to the extent 

 explained (for many of these see 

 volumes of Philosophical Trans- 

 actions at the time when light- 

 ning was attracting the attention 

 of the Royal Society), but not 

 an exception is yet known, al- 

 though this query has been pub- 

 lished far and wide among elec- 

 tricians.
