Monstrosities,” by C. W. Hargitt; “A Redescription of Pariotichus

Beginning with the third volume, the American Journal of Physiol- 
ogy will be issued in monthly instead of quarterly parts. In this 
change, however, an increase in the total annual output is not con- 
templated. The first number under the new arrangement contains 
the following articles: “The Relaxation of the Bladder Muscles of 
the Cat,” by C. C. Stewart; “The Reaction of Amceba to Lights of 
Different Colors,” by N. R. Harrington and E. Leaming; ‘“ Metabo- 
lism in the Submaxillary Gland during Rest and Activity,” by Y. 
Henderson; “Studies in the Contraction of Smooth Muscle,” by 
R. S. Woodworth ; and “ A Comparative Study of Reflex Action after 
Complete Section of the Spinal Cord in the Cervical or Upper Dorsal 
Region,” by B. Moore and H. Oertel. The second number is made 
up as follows: “The Origin of Fibrinogen,” by Albert Mathews ; 
“A Contribution to the Comparative Physiology of Compensatory 
Motions,” by E. P. Lyon; “ The Functional Adaptability of Afferent 
Nerve Fibres,” by S. P. Budgett and J. Green, Jr.; and ‘“ Comparison 
of the Effects of Certain Inorganic Solutions and Solutions Contain- 
ing Serum Albumin on the Rhythmic Contractility of the Frog’s 
Heart,” by E. C. Walden. 
The second part of Vol. XV of the Journal of Morphology con- 
tains the following articles: “ The Ovarian Egg of Limulus, a Con- 
tribution to the Problem of the Centrosome and Yolk Nucleus,” by 
J. P. Munson; “The Lateral Line System of Batrachus Tau,” by 
C. M. Clapp; and “ Comparative Cytological Studies, with Especial 
Regard to the Morphology of the Nucleolus,” by T. H. Montgomery, 
Jr. It is to be regretted that while this number is dated November, 
1898, it should not have been issued till August, 1899.
