744 The Smithsonian Institution 



lished, except a "Monograph of the Bats of North America," 

 by Doctor Harrison Allen (1864). Many years afterward 

 (1895) a new edition of this monograph by Doctor Allen 

 was published as a " Bulletin of the United States National 

 Museum" (1893). 



In 1889 "A Review of the Family Delphinidaj," by Fred- 

 erick W. True, was also issued as a Bulletin of the United 

 States National Museum." 



The first part of an " Arrangement of the Families of 

 Mammals" (1872) was published by Theodore Gill, but the 

 completion of the work was prevented by the poverty of the 

 collections in foreign material. 



Several physiological memoirs were also issued by the In- 

 stitution, as follows : " On Strain and Overaction of the 

 Heart," by Doctor J. M. Da Costa (1874), the "Dual Action 

 of the Brain," by Doctor C. E. Brown-Sequard (1874), and 

 "The Effect of Irritation of a Polarized Nerve" (1880), by 

 B. F. Lautenbach.
