1890.] MICKOSCOPICAL JOUENAL. 41 



NOTES. 



The January number of the Amei-ican Naturalist comes promptly 

 to hand from the new publishers, Ferris Bros., Philadelphia. Not- 

 withstanding the very unfortunate arrearages of 1889, three numbers of 

 which are still due, those for 1S90 are promised with regularity. The 

 missing numbers for last year will also be issued as rapidly as possible. 

 With such assurances from the publishers, we think it safe for our 

 friends to co-operate in supporting this scientific periodical. Its price 

 is $4.00 per year, but to our subscribers there is a saving of 50 cents. 



The last number contains an interesting article by Prof. Fewkes on 

 the vSea Urchin, an article on Garden Vegetables by E. L. Sturtevant, 

 and the usual summaries of Geography, Geology, Mineralogy, Botany, 

 Zoology. Embryology, Physiology, Ethnology, Entomology, and two 

 reprints in Microscopy. 



Photo-Micrography. — On Tuesday evening, February 11, Dr. 

 L. H. Laudy gave an illustrated lecture at the School of Mines, Co- 

 lumbia College, New York city, upon this subject. Those who at- 

 tended saw some of the best pieces of work of this kind that have ever 

 been executed. Dr. Laudy's skill as a photographer, combined with 

 his successful adaptation of the microscope to photographic work, have 

 given him results hitherto unattained in this field of applied science. 

 It is useless to attempt to describe these results ; they must be seen to be 

 appreciated. — Anthony s bulletin.
