artificial fecundation was performed. Three pots of one room 
were fecundated with pollen taken from the stamina, bursted but 
not widely open (recent or fresh pollen). The pots of the other 
room were fecundated with pollen gathered in the morning and 
kept until midday in paper. From the three first pots 120 grains 
were obtained and 96 only from the others. Sown the following 
year, the 120 seeds gave 112 plants with only 6 females; the 96 
seeds gave 89, all females.

After having obtained such results with plants, animals were 
taken for experiments. 
Rabbits .—A black female was covered by a white male, the 
same day by a gray male, and the next day after 18 hours by 
the first white male. The doe rabbit had a litter of five little ones, 
four females and one male. One white and one white and. black 
female came from the first coit with the white rabbit, one black 
and one gray with black spots came from the gray rabbit, and 
one white male with black spots was from the second coit with 
the white rabbit. 
Dogs .—A white female was covered successively by a red¬ 
dish male and then the same day by a white one. The following 
day, about 19 hours after, she again received the reddish male. 
She had three pups, one red female, one white and one male, 
spotted. 
Therefore, in general, after a single connection with a rabbit, 
abstemious, which has had no coit since a few days, a doe will 
give birth to two or three females; and if the rabbit has per¬ 
formed coit the day before, on the contrary two or three males 
will be born. Likewise in dogs, a single coit gives ordinarily one 
or two females, if the slut has been fecundated by a dog that has 
not coited since several days ; or, again, one or two males if the 
dog has covered another slut the day before. 
This has also been proved by Ciesielski in horses and with 
bulls. Looking into the registers of Mikolaow-Drohowyze
