a skin of the latter before me, which measures from the nose to the 

 tail 4 feet 5 inches, the width of the skin being 2 feet 8 inches ; while 

 that of the Black Tiger, which is half an inch less in size, measures 

 in width 2 feet 10 p inches. This may arise from the skin being more 

 stretched ; it proves nevertheless the strong make of the animal. I 

 do not observe the tawny spot above each eye mentioned in my de- 

 scription of a skin from a similar animal given in the ' Annals' (iv. 

 p. 325) ; this spot may vanish with the more advanced age of the 

 animal."

BIBLIOGRAPHICAL NOTICES. 



A Manual of the British Alga. By William Henry Harvey, Esq, 

 London, 1841. Svo. Van Voorst. 



We hail with pleasure another of Mr. Van Voorst's excellent publi- 

 cations on natural history — A ' Manual of the British Algse,' by Mr. 

 Harvey. The author remarks in the Introduction, p. 53, 



" The want of a work in the Engb'sh language, entirely devoted to the 

 British Algae, in which fuller descriptions should be given than the scope of 

 Hooker's ' British Flora' admitted of, and in which all the known species 

 should be included, has long been felt by lovers of this branch of botany. 

 Had my friend Dr. Greville completed, as was once his intention, his ad- 

 mirable ' AlgtB Britannicffi,' no room would have been left for my humble 

 labours, nor should I for a moment wish to take the subject out of such able 

 bands. But his work unfortunately stopped short with tlie ' marticulate ' 

 tribes, nor has he at present any intention of resuming it. The task has 

 consequently fallen on my shoulders, and my object will be gained and my 

 ambition fully satisfied, if, in the following pages, I have succeeded in af- 

 fording any assistance to the researches of my fellow-students. I could have 

 Avished, and indeed had intended, that the work should be illustrated with 

 figures, at least of the genera ; but n>y limited stay in Europe did not afford 

 time to prepare them, and it does not now appear desirable to delay the 

 publication till they could be got ready. However they might have added 

 to the beauty of the book, the student will experience little loss by their 

 omission who takes this Manual for what I v/ish it to be, a companion to 

 the ' Alg.f, Damnonienses, imhlished and sold by Mary JJ'i/aff, dealer in 

 shells, Torquay;' a most important work, now extending to four volumes, 

 with a Supplement, composed of specimens of 234 species, beautifully dried 

 and correctly named. These volumes furnish the student with a help, such 

 as no figures, liowever correctly executed, can at all equal — Nature's own 

 pencil illustrating herself." 



Mr. Harvey's Manual is got up in the style and tjj)ography of the 

 ' English Flora' of Sir J. E. Smith, and will range with it as a sup- 

 plementary volume. 



That a work such as the one now before us, embodying all the 

 species added to our catalogue since the publication of the 2nd vol
