LIFE OF FLOWER 103 



publication of the abstract proves that these studies were 

 commenced, and the memoir in question completed, be- 

 fore (and not, as stated by Professor M'Intosh, 1 after) 

 the author's appointment to the Conservatorship of the 

 Museum of the College of Surgeons, which did not take 

 place till the year 1 86 1 . The brain of another monkey 

 was also described in a paper on the anatomy of a South 

 American species then known as Pithed a monachus, which 

 appeared in the Zoological Society's Proceedings for 1862. 

 In the following year (1863) he published, in the 

 Natural History Review, a still more important com- 

 munication, dealing with the brain of the Malay siamang 

 (Hylobates syndactylus), one of the man-like apes, in 

 which it was shown that in this species (and probably 

 therefore in gibbons generally) the posterior part of the 

 cerebrum, or main division of the brain, overlapped the 

 cerebellum, or hind brain, to an even less degree than in 

 the American howling-monkeys, which had hitherto been 

 regarded as the lowest members of the group, so far as 

 the feature in question was concerned. That such a 

 feature should occur in one of the highest groups of 

 apes was certainly a remarkable and unexpected dis- 

 covery. Yet another contribution to the same subject 

 was made in 1864, when a paper appeared in the 

 Zoological Society's Proceedings on the brain of the red 

 howling-monkey, then known as Mycetes seniculus, but 

 of which the generic title is changed by many modern 

 naturalists to Alouata. 



The earlier memoirs of this series published (in the 

 Philosophical Transactions), writes Professor M'Intosh in 

 the Scottish Review for 1900, "formed important evidence
