Audibertia Taseyi, n. Sp. — A low, branching shrub; flowering 

 branches stout and rigid, the herbaceous upper portions whitish, ciner- 

 eous puberulent and viscid-glandular; leaves lance-ovate, acute or ob- 

 tusish, I to i^ inches long, narrowed into rather slender petioles y^ 

 to Yz an inch long, crenulate, not manifestly rugose, coated with a 

 close white tomentum ; heads of flowers about 6, in virgate spikes, i 

 to 2 inches apart, lower ones subtended by a pair of leaf-like bracts; 

 the inner floral bracts lanceolate to linear, setaceously acuminate ; 

 broad upper lips of the calyx furnished with a single conspicuous awn, 

 the two teeth of the lower one likewise awned ; corollas from ^ to ^ 

 of an inch in length, exceeding the bracts,; stamens and styles exserted

Carnivorous Plants. V.— Experiment No. XII —Placed 

 upon a leaf a small fiber of muscle drawn from a piece of boiled beef, 

 at 3 P. M.. June 12, '79. The fiber was teased out from the mass of 

 muscles and rolled into a ball having its diameter about 1-12 of an inch. 

 15 min. no change visible. 



30 " a few of the suhmarginal tentacles had inflected slightly. 

 45 " the tentacles of last note nearly touched the specimen; a 

 number of the other submarginal tentacles had movent con- 

 siderably ; a few of the marginal tentacles were also inflected. 



1 hr. all the submarginal tentacles were more or less inflected and 



nearly all touched the meat; all but ten of the marginal ten- 

 tacles were also inflected, varving in degree; the ten were 

 still fully reflexed. 'I'o four of these another experiment was 

 applied which will be fully explained in its proper place. 



2 hrs. practically there was no change except that six of the ten 



marginal tentacles mentioned in last note had inflected 

 slightly. 



3 "no important change. 



15 " all the tentTcles were inflected and touched the meat except 

 the four mentioned above whirh still normally reflexed. 



24 " the edges ot the leaf still remnined normal. 



48 " the meat uion the leaf seemed to be enclosed in asenii-trans- 

 parent fluid containing fat globules as shown by removing 

 a ])ortion by a blunt needle and placing under the microscope. 

 The globules were soluble in ether. The body of the meat 

 itself had assumed a dark br^iwn color. The tentacles and 

 leaf remained the same as the last note. 



72 " nothing but an opaque yellowish substance remained upon the 

 kaf. 



96 " there was but little change. 

 120 " the oi)nque substance upon the leaf had changed into a nearly 

 transparent thickish fluid.
