hymenium, and sometimes the spores, blue violet or various 

 shades of red. The medullary layer of lichens is often colored 

 blue by iodine. The plants will well repay the study and in- 

 stead of being very simple they will be found to be very com- 

 plicated plants. They belong to the Carposporse and partake 

 of the nature of both fungi and algae. 



After soaking the apothecium in water instead of crushing 

 and teasing, fill the cup with potassium h3^drate. Then with a 

 spatula scrape the inside and place a small portion on a slide. 

 In this way the h3^menium will frequently be removed intact 

 and will display the theke, paraphyses and spores. 



RECENT PUBLICATIONS. 



The Journal of Marme Zoology and Microscopy. Vol. 1, No. 1. 

 Nov. 1893. 



This is a biological quarterly dealing with the fauna of British 

 seas ; and contains many interesting facts and accurate descrip- 

 tions, in plain wording and accompanied by original illustrations. 

 Personal observations upon the habits of marine animals, to- 

 gether with notes and short articles upon the numberless pro- 

 blems of shore and ocean life, form leading features. The en- 

 deavour is to avoid the technical language too frequently met 

 with in Zoological writings, as well as to keep the pages free 

 from trivialities and thread-bare expositions of text book matter. 



The Microscopical section consist of "Studies" which deal in 

 pleasant but exact manner with the anatomy, life-history and 

 habits of noteworthy microscopical animals. In this way are 

 treated the Protozoa, the spicular Sponges, the young stages of 

 Zoophytes, Worms, Crustaceans and Ascidians. Thus the studies 

 form a series of most interesting articles of great value, as many 

 of the facts are original, and of a nature not to be met with in 

 ordinary text books. 



Two full-page lithographed plates, sketched from life, and of 

 first class execution, are, in each number, devoted to the original 

 illustration of the microscopical Marine life treated of in the 

 ''Studies." To add to the value of these illustrations, they are 

 often coloured. To ensure accurac}^ this is done by hand. There 

 are also reviews, the record of Zoological progress, hints on 

 Microscopical mounting, Exchanges, &c.
