Iowa Geoloprical Survey he has prepared a preliminarj- report on coal, a sketch of 

 the geolo<?ical formations of Iowa, an annotated catalogue of minerals and a 

 bibliograpUy of Iowa geolofjy. Has published besides the following papers: 



The Principal Mississippian Section.' 



The Classification of the Iowa Carboniferous Rocks of the Mississippi Valley.* 



The Platyceras Group of Paleozoic Gasteropods.^ 



A. Remarkable Fauna at the Base of the Burlington Limestone in Northeastern 

 Missouri.* 



The Present Basal Line of Delimitation of the Carboniferous in Northeastern 

 Missouri.'* 



" Nickel Ore " from Iowa." 



Besides a number of shorter notes, reviews and newspaper articles. 

 Prof. S. W. Beyer has prepared for publication a preliminary report on certain 

 <ieep wells in the State in connection with his investigations on the artesian waters 

 for the Iowa Geological Survey. 



Our botanists are also few in number at present, but are not inclined to take a 

 back seat on that account. 



Prof T. H. McBride, of the State University, has published a beautifully ill- 

 ustrated account of the " Myxomycetes of Eastern Iowa."' Sixty-six species are 

 described. 



A feature which surely will prove of great value to botanists is the keys to fam- 

 ilies and genera scattered through the work. 



Prof. McBride is now extending his labors to the Fungi of North America. 



Review of " Monograph of the Myxomycetes." Ger. Marssee, London. (In 

 press.) 



Prof. L. H. Pammel, of the Agricultural College, has published the following 

 papers: " On the Seed Coats of the Genus Euphorbia;"' Illustrated; with a par- 

 tial Biblliography. He concludes that the seed coats offer few characters of sys- 

 tematic value. 



" Fungus Disease of the Sugar Beet," especially in Iowa. 



"Temperature of Plants,'' read at the Rochester Meeting of A. A. A. S., show- 

 ing that temperature in shaded ground is lower than in open ground. 



Report on "Some Observations on Parisitic Fungi in 1892." The fluctuations 

 of temperature were very sudden. Peach trees suffered greatly hom Taphrina 

 ■deformans, T. amea, T.^jruni, Puccinia rubigo-vera and P. graminis were reported 

 as common. 



Prof. Pammel is now working on a paper on the " Chromogenic bacteria,'' at 

 Ames, in which a full bibliography and descriptions of new species will appear. 



He is also carrying on a series of experiments in crossing curcubito, which show 

 that the species ^perimented with will not cross. 



Among the zoologists active work has been carried on as follows : 



Oilman Drew has been observing the habit of dragon flies. 



Prof. H. W. Norris, of Iowa College, has made an important contribution to 

 animal morphology in the shape of a paper on " The Development of the Auditory
