. Animal biology. Zoology; Biology. PARAMECIUM 73 comes in contact with a solid object, assuming it to be swimming at full speed forward, the force of the contact produces a negative response. The animal backs up, pivots upon its posterior end, and swims forward again. If it again strikes the object, it exhibits the same negative reac- tion, which is repeated until on swimming forward the animal passes the obstacle (Fig. 21). Though it is called an avoiding reaction, which would imply a consciousness on the part of the animal, all that it is doing is simply giving a series of negative response

The term' 'avoiding reac- tion" thus gives rise to impHcations which are unwarranted, a fact usually indicated by inclosing the words in.
