THE POPULAR SCIENCE MONTHLY. 



ogist removed the cerebellum from pigeons 

 in successive slices, and found that, on cut- 

 ting away the superficial layers of the organ, 

 there appeared only a slight feebleness and 

 want of harmony in the movements ; but 

 that when the deepest layers were removed 

 the animal lost completely the power of 

 standing, walking, leaping, or flying. Voli- 

 tion and sensation remained ; the power of 

 executing movements remained ; but the 

 power of coordinating those movements 

 into regular and combined actions was lost. 

 Flourens's experiments have been again and 

 again repeated, always with the same re- 

 sults. But now the subject has been in- 

 vestigated anew by Ovsiaunikoflf, whose 

 conclusion is that, even though the entire 

 cerebellum be cut out, the faculty of coor- 

 dination still remains. In one of his ex- 

 periments a rabbit remained alive during 

 two whole weeks after all the upper half of 

 the cerebellum was cut out, nor did it lose 

 its faculty of coordinating its movements af- 

 ter all the cerebellum was cut out until an 

 effusion of blood produced this result. 



Appearance and Habits of the Andaman 

 Islanders. The natives of the Andaman Isl- 

 ands are described by Surgeon-Major Hod- 

 der, of the British Army, as not exactly pre- 

 possessing in appearance, though not de- 

 formed and hideous, as has been stated. 

 In height they vary from four feet nine 

 inches to five feet one inch; they are ex- 

 tremely black, more so than the African 

 negro, and some of them have " a dull, 

 leaden hue, like that of a black-leaded 

 stove." They are fond of dancing, have 

 a strong sense of the ridiculous, are exceed- 

 ingly passionate, are easily aroused by tri- 

 fles, and then " their appearance becomes 

 diabolical." The men go entirely naked, 

 and the women nearly so. They cover their 

 bodies with rod earth, and, as ornaments, 

 wear strings of their ancestors' bones round 

 their necks, or a skull slung in a basket 

 over their shoulders. They are tattooed 

 all over their bodies ; their heads are shav- 

 en, with the exception of a narrow streak 

 from the crown to the nape of the neck. 

 They rarely have eyebrows, beard, mus- 

 tache, whisker-;, or eyelashes. They are 

 very fond of liquor and smoking ; are 

 short-lived and not healthy, not many pass- 



ing forty years of age. Their language 

 consists of few words, harsh and explosive, 

 and chiefly monosyllabic. Almost their 

 only amusement is dancing to a monoto- 

 nous chant and the music of a rough skin 

 drum, played by stamping with the feet. 

 Their courtship and marriage usages are 

 very simple. The male candidate for matri- 

 mony eats a sort of ray-fish, which gives 

 him the appellation of "goo-mo" bachelor 

 desirous of marrying. The marriageable 

 girls wear a certain kind of flower. The 

 ceremony consists in the pair about to be 

 married sitting down, apart from the others, 

 and staring at one another in silence ; tow- 

 ard evening the girl's father or guardian 

 joins the hands of the pair ; they then re- 

 tire, and live alone in the jungle for some 

 days. The only manufactures of the island- 

 ers are canoes, bows, arrows, spears, and 

 nets. Of late years " homes " have been 

 established for the Andamanese, consisting 

 of large bamboo sheds, in which those who 

 come in from the jungle put up, coming and 

 going at will. They seem, however, to pre- 

 fer the jungle, and the attempts made to 

 cultivate their acquaintance do not appear 

 to have been very successful. 



The Ancient Rnins of Colorado. A cor- 

 respondent of the "Worcester Spy writes as 

 follows of certain highly interesting dis- 

 coveries recently made by the Geographical 

 and Geological Survey of the Territories 

 conducted by Dr. Hayden : 



"Prof. Hayden has given Southwestern 

 Colorado a new interest, by discovering and 

 describing the ancient ruins in that section 

 and in Southeastern Utah. The fertile val- 

 ley of the Animas was densely inhabited and 

 highly cultivated by an enlightened race of 

 people centuries ago. The ruins of the 

 houses, corrals, towns, fortifications, ditches, 

 pottery-ware, drawings, non-interpretable 

 writings, etc., show that many arts were 

 cultivated by these prehistoric people which 

 are now entirely lost. Their houses were 

 built of almost every kind of stone, from 

 small bowlders to the finest sandstone. 



" The finest of these ruins, and the near- 

 est perfect, are situated about thirty-five 

 miles below Animas City, in a large valley 

 fifteen miles long by seven wide, on the 

 west side of the river. This valley has
