1898.] MICROSCOPICAL JOURNAL 87 



Erythea.— This is a monthly journal of botany, west- 

 American in g"eneral, published monthly at Berkeley, Cal. 

 Price $1.50. Complete sets of back volumes may be 

 obtained. 



Bulletin of Buf¥alo Society of Natural Sciences. — Hand 

 book for students and amateurs in g"eolog-y and palaeon- 

 tology descriptive of the 18 mile creek near Buffalo, has 

 been issued. It contains 27 full pag-e plates made from 

 photographs of the formations found along this stream. 

 It is by A. W. Grabau of the Massachusetts Institute of 

 Technology and later of Harvard University. It deserves 

 the very highest commendation. 



The Society has also issued a review of the North 

 American Delphacibae, a large group of small active 

 insects which at times injure leaves and fruit of economic 

 plants. 



Some North American Coniferae. — Prof. E. S. Bastin 

 and Henr}' Trimble have published a series of papers in 

 the American Journal of Pharmacy and have reprinted 

 them in a pamphlet of 124 pages on the Pinus strobus and 

 numerous other pines. They have given especial atten- 

 tion to the microscopic structure and chemical composi- 

 tion. The microscopical structure is described and illus- 

 trated by 58 figures consisting of cross-sections of stems, 

 leaves and bark. Their studies have led also to a descrip- 

 tion of the turpentine industries. The cross-sections 

 have been magnified from 75 to 100 diameters and show 

 nicely the epidermis, hypoderma, stomas, periderm, bast- 

 layer, combium, xylem, lacuna, medullary rays, sclerotic 

 cells, tannin cells, mesophyll cells, phloem, tracheids, 

 transfusion tissues, resin passages, stone cells, mucilage 

 cells, cork formation, crystal cells, and contained crystals. 



This publication was intended to be the first of a series 

 dealing with botany, histology, chemistry and economics 

 of the cone bearer, but was interrupted and delayed by 

 the death of Prof. Bastin. Presumably copies of this 

 pamphlet may be obtained from Prof, Trimble of Phila- 

 delphia.
