thicker pad. If the pad be too thin some moss capsules filled with nearly ripe 

 spores will be crushed by the pressure. 



The chief advantages of this method are convenience and the fact that 

 the plants can be arranged on the glass in the light instead of on the sensitized 

 paper which has to be in a measure protected from the light. 



To keep the printing frame at right angles to the sun's rays, stick a pin in 

 the upper surface of the wood of the printing frame and perpendicular to it' 

 then hold the frame so that the shadow of the pin's head just covers its point. 



OBITUARY. 



Monsieur Emile Bescherelle, a bryologist of note, and a man of diverse 

 activity, died on February 26th of the present year, at Arcachon, Gironde, 

 France, in his 76th year. Besides his immediate circle of relatives and per- 

 sonal friends, who are numerous, the moss students of the whole world are 

 left to mourn the loss of this earnest, energetic and genial man. For in a 

 letter, dated July, 1899, he informed the writer that he was interested in 

 "the mosses of the whole world." This statement is w^ell borne out by a 

 glance at the numerous publications from his pen. His bryological activity 

 extends over nearly forty years. His writings are found in the Bulletin of 

 the Botanical Society of France, in the Journal de Botanique de M. Moret, 

 and in the Revue Bryologique; the principal memoirs are printed mostly in 

 the Annales des Sciences Naturelles. Of these the following are the most 

 important : 



Prodromus Bryologise Mexicanae (1871). Florule Bryologique de la 

 Nouvelle Caledonic (1873). Florule Bryologique des Antilles Frangaises 

 (1875). Mousses de Paraguay (1875). Florule Bryologique de la Reunion 

 (1880). Catalogue des Mousses de I'Algerie (1882). Flore bryologique du 

 Tonkin (1887). Mousses du Cap Horn et Magellan (1889). Musci Yun- 

 nanenses (1892). Flore Bryologique du Japon (1893). Mousses de Lehmann 

 Amerique Centrale (1894). Flore Bryologique de Tahiti (1895). Essai sur 

 le genre Calymperes (1896). Mousses de la Tunisee (1897). Flore bryolo- 

 gique de Tahiti Supplement (1898 ) . Flore bryologique du Japon. Supplem ent 

 (1899). 



This selected list shows the range of Mr. Bescherelle's interests. His 

 energy did not abate till shortly before his death. And while he has not 

 worked on North American mosses, his work on West Indian, Central Amer- 

 ican and South American mosses is so considerable that it will ever place his 

 name prominently among American bryologists. 



Incidentally it may be of interest to note that Mr. Bescherelle was Chief 

 of the Honorary Division, under the Minister of Public Works; former Presi- 

 dent of the Botanical Society of France; Corresponding Member of the 

 Museum of Natural History: Chevalier of the Legion of Honor ; and " Officier 

 d' Academic." J. M. Holzinger.
