jaspers, possibly of middle Devonian age, 

 at Bingera and Barraba. At Tamworth 

 there is a radiolarian series at least 2,000 

 feet thick. The radiolaria are abund- 

 antly distributed through claystones 

 and cherts in the form of chalcedonic 

 casts. These are associated with lime- 

 stones containing Stromatopora, Favos- 

 ites, gothlandica, Pachypora, and Heliol- 

 ites. At Jenolan caves, overlying the 

 cave limestone, are clay shales and 

 cherts containing radiolaria. The Cave 

 limestone contains Stromatopora, and 

 Pentamerus knightii. 



The radiolaria are best preserved and 

 most abundant in the cherts, towards the 

 formation of which they must have con- 

 tributed largely. Under the microscope 

 they appear as spherical or oval bodies 

 up to two millimeter in diameter. Traces 

 of the latticed structure are not infre- 

 quently shown. The best preserved spec- 

 imens occur in thin bands of siliceous 

 limestones, and are well shown by etch- 

 ing a slice with weak acid. While the 

 original siliceous skeleton is generally 

 preserved, it is sometimes replaced by 

 pyrites. Often internal casts in chal- 

 cedony alone remain. The forms present 

 fall for the most part in the group 

 Spumellaria. G. W. C.

The University of Pennsylvania is 

 gradually bringing the equipment of her 

 Biological department up to the latest 

 and best standards. The zoological sude 

 is to have a "live house," now in process 

 of erection, which will afford unusual 

 facilities in the study of habits, habitats, 

 breeding seasons, etc. It is the purpose 

 of Professor Conklin to stock the viva- 

 rium with representatives of all the 

 groups of animals, from monad to 

 monkey. There can be no doubt that a 

 long felt want will be filled, and the 

 University is to be congratulated on 

 being not only the first in the country, 

 but the first in the world, to make such 

 provision for zoological investigation.

The department of Biology, University 

 of Missouri, will be conducted by the 

 following corps of teachers: Howard 

 Ayers, S. B., Ph. D., professor of Bio- 

 logy; Chas. Thorn, A. B., A. M., instruc- 

 tor in Botany; Clarence M. Jackson, B. 

 S., teaching fellow in Zoology. Instruc- 

 tion is given this semester in the follow- 

 ing subjects: General Biology of Animals 

 and Plants, Human Histology, Mammal- 

 ian Embryology, Comparative Anatomy 

 of Vertebrates, Vertebrate Zoology, Re- 

 search in Morphology of Fishes, Plant 

 Physiology, Research in the Grasses of 

 the United States. H. A. 



Recent appointments in the depart- 

 ment of botany of the University of Ne- 

 braska are as follows: Frederic £3. 

 Clements, Ph. D., to be instructor in 

 Botany (advanced from assistant) ; Edna 

 L. Hyatt, Botanical Artist (reappointed); 

 Cora F. Smith, B.Sc. to be Fellow in Bot- 

 any; Albert F. Bill, B. Sc, to be Fellow 

 in Botany. 



The summer session of the University 

 of Nebraska for this year was six weeks 

 long. In the botanical laboratory one 

 semester's work in general botany was 

 offered, and by fully three-fourths of the 

 class satisfactorily completed. The work 

 Included a daily lecture, about one 

 hundred having laboratory work. As 

 the class was made up entirely of 

 teachers in the graded and high schools, 

 the importance of this work to the 

 schools of Nebraska can scarcely be 

 over-estimated. 



The Biological department of the Uni- 

 versity of California is to be conducted 

 during the coming year by the following 

 professors and assistants: Natural His- 

 tory and Geology, Prof. Jos. LeConte, 

 Wm. E. Ritter, associate; Zoology, Prof. 

 H. P. Johnson, H. P. Tory, instructor. 



The new laboratories for Plant Physio- 

 logy at the University of Chicago will 

 be opened October 1st, under the di- 

 rection of Prof. Chas. R. Barnes. They 

 will occupy the fourth floor (50x102) of 

 the Hull Botanical Laboratory, which 

 has been especially fitted up for this pur- 

 pose. A sufficient amount of supplies and 

 apparatus will be provided in the course 

 of the year for the regular courses, arid 

 apparatus for research will be construct- 

 ed or purchased as needed in the future. 

 About a dozen graduate students have 

 already indicated their intention of 

 registering for the new course. The 

 laboratories are supplemented by a 

 roof greenhouse about 30 by 60 feet. A 

 competent gardener will be in charge. 



Mr. W. A. Riley, who has been assist- 

 ant in the department of Biology of De- 

 Pauw University for the past three years, 

 will spend the coming year in study in 

 the department of Invertebrate Zoology, 

 Cornell University. Mr. H. H. Zim- 

 mermann will take Mr. Riley's place in 

 DePauw laboratory. 



The following is a brief outline of the 

 more important courses offered in the 

 Geological Department of Johns Hopkins 

 University, this year, in which work 

 with the microscope forms an essential 

 feature:
