SCIENCE. 



[Vol. I., No. 18. 



course of his woik on the turbellarians, has 

 already produced some extremely important 

 papers on their morpliologj', and the relations 

 of plathelminths generally. The monograph 

 of Dr. Mayer, on the curious crustacean fam- 

 ily Caprellidae, has just appeared, and the 

 ' Copepoda ' of Dr. Giesbrecht is rapidly ap- 

 proaching completion. To the two zoologists 

 last named belongs the credit of most of the 

 great improvements in technique which have 

 been invented in the station. The value of 

 these improved methods can scarcely be over- 

 estimated. Technical difficulties often stand in 



the gulf, and to contain a body of accurate in- ' 

 formation on the anatomy, histology, classifl-'^ 

 cation, and relations of marine forms, which 

 shall serve as a sound basis for future investl- . 

 gations. The series includes Algae as well as 

 animals. They maj' be written in either of 

 the four generallj' known European languages. 

 Six have already appeared, the first being the 

 beautiful work of Dr. Chun on the Ctenophorae. 

 One by Dr. Emerj' has already appeared in 

 Italian ; and the Actiniae of Dr. Andres will 

 shortly be published in the same language. 

 They are published by subscription, of which the 

 annual amount is I12..50, and the number of 

 subscribers, up to the present, is two hundred 

 and sixty. The station also issues a journal for 

 original memoirs of work done in its labora- 

 tories, called the ' Mittheilungen aus der zoolo- 

 gischen station,' which commenced in 1879, 

 and whose three volumes contain alreadj' much 

 important work ; also a bibliograplij', called 

 the ' Zoologische jahresbericht,' in which 

 every paper on biological subjects is not only 

 indexed, but summarized. The latter was 

 commenced in 1880. 



It will be allowed that the zoological station 

 has alread}^ a manj'-sided activit}' ; that it 

 has done, and is doing, a great deal for bio- 

 logical science ; nevertheless, it is about to 

 take a still further expansion. A separate lab- 

 oratorj" is in course of preparation for the 

 studjr of comparative phj'siology, for which 

 nowhere such favorable conditions could be 

 found as will be provided \>y the resources of 

 the existing station. Everj' one who is a 

 friend to the progress of biology must wish 

 the Neapolitan station success in its new en- 

 terprise, and a continuance of the successful 

 development which has, up to the present, 

 taken place in the original institution.

the way of the solution of definite and impor- 

 tant questions : before them the investigator is 

 brought to a stand-still, and his advance in 

 the desired direction hopelessly blocked. The 

 discovery of a rapid and certain method of ob- 

 taining series of sections, wliich science owes 

 to Dr. Giesbrecht, has given a new power to 

 research, and enabled investigations to be 

 undertaken which before were impossible. 



The publications of the station have alreadj' 

 been mentioned, but it is well to add a few 

 details concerning them. The monographs 

 are intended to form a series of complete 

 studies of every group of animals existing in 



EVIDENCES OF GLACIATION IN 

 KENTUCKY. 



The following notes of observations on gla- 

 cial action south of the Ohio Eiver are sub- 

 mitted to the fund of evidence of glaciation 

 anterior to the period of the great terminal 

 moraine. 



1. At the crossing of the Kentucky River 

 by the extension of the Kentucky Central R.R., 

 opposite the mouth of Otter Creek, and in 

 Clark County on the north bank of the river, 

 the following fresh section was obtained at the 

 mouth of the railway-tunnel.
