 treatment throughout, is rivaled by but few, 

 excelled by none. F. G. Wieohmann. 



SCIENTIFIC JOURNALS AND ARTICLES. 

 The Botanical Gazette for June contains 

 the following articles: Dr. Eoland Thaxter 

 publishes a further contribution on the Myxo- 

 bacteriacese, especially in reference to the work 

 of Migula, Zukal, Miss A. L. Smith and 

 Zederbauer; also establishing eight new spe- 

 cies. John Donnell Smith contributes his 

 twenty-sixth fascicle of ' Undescribed Plants 

 from Guatemala and Other Central Amer- 

 ican States,' describing twelve new species. 

 Thomas H. Kearney asks the question, ' Are 

 Plants of Sea Beaches and Dunes True Halo- 

 phytes ? ' reaching the conclusion that these 

 are not generally halophytic. Alice East- 

 wood publishes fourteen new species of west- 

 ern Polemoniaceae. George J. Peirce, in 

 ' Notes on the Monterey Pine,' shows that the 

 difference in the quantities of water and 

 solutes drawn up through the xylem into 

 galled and normal leaves furnishes the reason 

 for the differences in the amount of conduct- 

 ing tissue as shown by the annual rings. In 

 other words, amputated seedlings and branches 

 bearing galled leaves develop bundles which 

 vary from the normal according to the degree 

 of injury which the leaves have undergone. 

 This is confirmation of Jost's conclusion that 

 leaves and vascular bundles are closely cor- 

 related in their development. Amon B. Plow- 

 man publishes the ' Celloidin Method for Hard 

 Tissues ' as developed and perfected by Pro- 

 fessor E. C. Jeffrey. M. A. Chrysler pub- 

 lishes ' Anatomical Notes on Certain Strand 

 Plants,' being the results of a comparative 

 study of the leaf anatomy of certain plants 

 in the vicinity of Woods Hole and near Lake 

 Michigan. Charles E. Allen makes a prelim- 

 inary announcement of his conclusions in ref- 

 erence to chromosome reduction in Lilium 

 canadense, being quite different in some points 

 from those previously maintained. 



The June issue of the Bulletin of the Mich- 

 igan Ornithological Cluh contains the follow- 



ing articles : ' Some Notes on the Life His- 

 tory of the American Redstart,' by J. Claire 

 Wood, with a full-page cut of the species by 

 Louis Agassiz Euertes. Bradshaw H. Swales 

 concludes his ' List of the Land Birds of 

 Southeastern Michigan.' A. H. Griffith con- 

 tributes ' Birds in Decoration,' which is il- 

 lustrated by specimens of Japanese art from 

 the Detroit Museum of Art. P. A. Taverner 

 writes on the ' Tagging of Birds ' as a means 

 of solving some of the vexing problems of 

 migration. Walter B. Barrows describes the 

 ornithological and oological collections of the 

 Michigan Agricultural College, which is sup- 

 plemented by a half-tone of the interior. 

 Alexander W. Blain, Jr. notes the capture of 

 ' Three Rare Michigan Birds.' There are 

 other notes of value and the Usual reviews. 

 With this issue Professor Barrows becomes 

 one of the editorial staff. 



SOCIETIES AND ACADEMIES. 



THE RESEARCH CLUB OF THE UNIVERSITY OF 

 MICHIGAN. 



At the meeting of the club held April 27 

 Dr. Novy presented the results obtained in 

 collaboration with Mr. McNeal on the cul- 

 tivation of the organisms causing trypanoso- 

 matic diseases. These investigators have been 

 able to cultivate three of these protozoa. The 

 organism Trypanosoma lewisi has now been 

 under cultivation for two years. T. brucei, 

 the cause of nagana or the tsetse-fly disease of 

 South Africa, has been under cultivation since 

 last August. The culture medium sent from 

 Manila, after inoculation with the trypano- 

 some from a cow suffering with surra, on 

 arrival in Ann Arbor, showed an excellent 

 culture of this organism which had developed 

 en route. This organism was kept alive for 

 sixty-five days, but all efforts to secure infec- 

 tion in animals or to obtain subcultures failed. 



A comparison of the trypanosome from the 

 Philippine suiTa with that from the Island 

 of Mauritius seems to indicate that the two 

 are entirely distinct. 



The cultural characteristics of the Phil- 

 ippine trypanosome are such as to distinguish
