The type of Hydrochceris is JET. hydrochcenis 

 'Brisson=Sus hydrocharis Linn. (12th Ed.), 

 which becomes Hydrochcenis hydvochceris 

 (Linn.) 1766. 



The type of Tapiriis is T. tapirns Brisson= 

 Sippojwtamiis terrestris Linn., which becomes 

 Tapirus terrestris (Linn.) 1758. 



The type of Cuniculus may be fixed on C. 

 Cauda longissima Brisson, which becomes 

 Cuniculus alaetaga (Olivier) 1800.* Cuni- 

 cidus is one of the few genera in which Bris- 

 son did not indicate the type by repeating 

 the generic name for the first species. It 

 was made up of a heterogeneous assemblage 

 comprising no less than six modern genera 

 and five families of Rodents as follows : 



The tj'pe of Lidra is L. Intra Brisson:= 

 Mustela Intra Linn., which becomes Imtra 

 Intra (Ltun.) 1758. 



C. Haet Merriam. 



{Dasyproctidce) 



Cawa Pallas 1766 (Caviidce) 



Leinmus Link 1795 {Muridw) 



Ccelogenus Cuv. 1807 



Dasyprocta 111. 1811 



Anisonyx Eaf. 1817 (Sciuridce') 



^^ Allactaga Cuv. 1836 (Dipodidce') 



According to the A. 0. U. Code, therefore, 

 Allactaga, having been left in Cuniculus until 

 all the others had been taken out, must 

 stand as the type of Cuniculus. 



The tjT^e of Glis is Glis glis Brisson= 

 Seiurus glis Linn. (12th Ed.), 1766, which 

 becomes GHs glis (Linn.) 1766. 



The type of Pteropus is P. pteropus Brisson 

 ^Vespertilio vampyrus Linn., which becomes 

 I^eropus vampyrus (Linn.) 1758, replacing 

 Pteropus edulis Auct.f 



The type of Hycena is H. hycena Brisson^ 

 Canis liyncea Linn., which becomes Hyncea 

 hyncea (Linn.) 1758. 



The type of Males is M. meles Brisson^ 

 Ursus meles Linn., which becomes Ileles meles 

 (Linn.) 1758.

 ELECTEO-HOETIOULTUEE. 



The latest results dra\\Ti from experi- 

 ments with electric light upon vegetation 

 are by Professor Eane in Bulletin No. 37 

 of the West Virginia Experiment Station. 

 Investigations along this general line began 

 in 1861, when Herve-Mango demonstrated 

 that electric light can cause the formation 

 of gxeen material (chlorophyll) in plants 

 and produce other phenomena, as turning 

 toward the light (helioti-opism). Pril- 

 leaeux, in 1869, showed that assimilation 

 in plants goes on in the presence of arti- 

 ficial light. Dr. Siemens experimented 

 largely with arc lights, both witliin and at 

 other times outside of and above the plant 

 houses. Professor Bailey, who at Cornell 

 University has tested electric lighting ex- 

 tensively dui-ing the past few years, in re- 

 viewing Dr. Siemens' work, wi-ites: "He 

 used the term electro-horticulture to desig- 

 nate this new application of electric energy. 

 He anticipated that in the future the horti- 

 culturist will have the means of making 

 himself particularljr independent of solar 

 light for producing a high quality of fruit 

 at all seasons of the year .... whatever 

 may be the value of electric light to horti- 

 culture, the practical value of Siemens' ex- 

 periments is still great." After years of 

 trial Professor Bailey stated in one of his 

 reports : " I am convinced that the electric 

 light can be used to advantage in the forc- 

 ing of some plants." 



In the fall of 1892 Professor Rane intro- 

 duced the use of the incandescent light in 

 place of the arc lamp, and his recent report 

 with its illustrations from photographs of 

 plants, etc., has features of interest to all 

 who are interested in science, as well as the
