PROCEEDINGS OF THE DAVENPORT ACADEMY OF SCIENCES. Vol IV. 1882-1884. Davenport, Iowa : Published by the Academy, 1886. This fourth volume of the proceedings of the Davenport Academy of Sciences contains a number of papers of permanent scientific value. Mr. J. C. Arthur continues his “ Contributions to the Flora of Iowa,” which have already attracted favorable notice in previous volumes. Dr. C. C. Parry has a number of botanical papers; and in his' chief contribution, “ Chorizanthe,” he has undertaken a complete revision of the genus, which has been received by botanists generally. and has been adopted at the'Royal Herbarium, Kew Gardens, England. The descriptions of new Blastoids and .Crinoids from the Hamilton group are accompanied by fine illustrations. But perhaps the chief interest of the volume centers in its archreologi- i cal contributions. Some of these are of more than] usual merit. Dr. Hoffman of the Bureau of Ethnology has an illustrated paper on Aboriginal Art In “California and Queen Charlotte's Island. An articlEi o:a the Ancient Pottery of the Mississippi Valley, by Mr. William H. Holmes, of the U. S.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
