Bailey (1967) reported that the mean condition index of 499 rabbits captured from 
May through November in 1964, 1965, and 1966 was 5-48. The October, November, and 
December averages in 1 968 are all significantly greater than Bailey's average. How¬ 
ever, since different individual workers may obtain different results when measuring 
the same rabbits, it is not possible to know if the rabbits were in better condition 
this fall than in 1964-66, or if the difference in averages only reflects different 
measurements by different workers. 
Several rabbits trapped in fall, 1968, had been captured the previous winter or 
before. The mean condition index of the rabbits recaptured in October 1 968 (6.14) 
was significantly greater (£< 0.025) than that of animals newly captured that month 
( 5 . 56 ). Similarly, in November 1968 the mean condition index of the recaptured 
rabbits (6.13) was highly significantly greater (P<C0.001) than that of animals cap¬ 
tured for the first time (5*52). No significant difference was detectable for 
December, probably because only 2 of the 44 animals captured in December had been 
captured before fall, 1 968 . The mean condition index of the two animals was 6.27, and 
of the remainder, 5*62.
