character of neiiro-muscular tissues. The contraction shows an obvious 

 sequence in fishes. Ganglia in the walls between ventricles and 

 auricles and between the auricles are responsible for the beat, but 

 proper co-ordination is brought about by nerve connection between 

 auricles and ventricles. The technical physiologist, by isolating the 

 physical, can enable the biological side of operations of living organisms 

 to have more concentrated attention at the hands of the zoologist. 

 Ludwig's ganglia are inhibitory. 



The happiness that one has in obtaining food (when Hungry) is to 

 be paralleled with the pleasure associated with collecting specimens 

 °of interest, whether Archaeological, Zoological, or Botanical, objects of 

 art, early printed books, or manuscripts, or inscription-bearing stones. 

 All these things, perhaps, (as does labour, skilled and unskilled) appeal 

 to the mainsprings of action. 



The desire to acquire begins when a child reaches out for a 

 glittering jewel, a bright light, a reflecting mirror. The child is 

 anxious to carry his coveted possession to his cot. Suggestions of a 

 like kind, or better evolved, may secure the attention of those who 

 have passed beyond childhood. It seems likely that the tendency to 

 imitate the muscular movements and their expressions may lead to 

 the evolution of emotions, and their ultimate repetition by association. 

 One hears from time to time observations on the attractions that 

 markets present for many, in a wide sense for most people. "Sell at 

 home and buy in the market" says the proverb, clearly pointing out 

 that only those who cannot buy in the market go to the place where 

 the material can be got. So the institution which Minerva herself 

 founded has been associated with civilization, and under her very eye, 

 or her devotees, the institution is worked. 



"S. S. 'Tis in the market place and street 

 I had my birth and breeding too. 

 And from a boy to blush and blink, 

 I scorn the thing as much as you," 



(Aristophanes.) 

 Suggestion by sight, hearing, or touch, may be in its nature, 

 warning, irritating, depressing, as well as stimulatory or restful. Charcot,
