130 Animal Morphology. 



both hear, see, and smell at one and the same time, and 

 the conscious ego is aware that it participates in all these 

 several advantages by a kind of plurality of ubiquity. 



This plurality of ubiquity in the paraitic senses, by in- 

 structing the somatic senses, is accomplished through the 

 brain ; and the brain, in function, is nothing else than the 

 medium of union and greater extension of limb development, 

 under a peculiar metamorphic differentiation, capable of 

 adapting these limbs, or special senses, to higher and more 

 extensive ranges of knowledge and perception. 



Instead of giving a minute detail and defence of this 

 singular view of the senses, here designated the paraitic senses, 

 a remarkably short and tabulated view of the tripartite 

 arrangement of membrane in the several paraitic senses will 

 be given, with scarcely an explanation or defence through- 

 out, as an outline forbids lengthened discussion. 



I. 

 TRIPARTITE MEMBRANE OF THE SENSE OF TASTE IN MAN. 



Mucous Membrane. Mucous membrane of the tongue and 



salivary glands, and hyoid bone. 

 Serous Membrane. Vocal cords and epiglottis. 

 Muscular Membrane. Constrictors of the pharynx, and 



muscles moving the tongue, as the glosso-hyoid and 



glosso-pharyngeal muscles, etc. 



II. 



THE TRIPARTITE MEMBRANE OF THE SENSE OF SMELL. 



Mucous Membrane. The Schneiderian membrane, the 

 lachrymal apparatus, and the lining membrane of the 

 Eustachian tube and Tympanum, the two latter divi- 

 sions being displaced portions of this membrane ; the 

 bony plates, as the turbinate bones, the vomer, the os 

 nasi, and the Palati bones.
