phase of the subject more in detail at a later date, and at that 

 time to consider further the method of these reactions, and to de- 

 termine to what extent the general behavior of the young lobsters 

 may be dependent upon these responses to stimulation by light. 

 In the meantime we may sum up the result of the observations thus 

 far made by the following table and then briefly consider the prob- 

 able influence of light on the general condition and rate of growth 

 of the lobster as presented in the following section. 



TABLE No. 1. 



Showing the nature of the photopathic reactions of lobsters in the first five stages 



on black and white backgrounds, and under the influence of white, 



red and blue light.* 



* In cases where the results were not certain, or not definite, or contradictory, the sign (7) 

 has been placed. A positive reaction is indicated by the + sign; a negative reaction by the 

 — sign.
