In studying the spermatozoa of the horse (Fig. 4) it was observed that their general characteristics and reaction to stain were similar to those of man, except that after the fluid had been kept for a few days the tails of certain cells appeared to be fibrillated. The measurements of equine spermatozoa were found to be : Total length, . to mm., or to in. Length, head, . (»6 to mm., or to in. Width, head, . to mm., or to in.

The head of each spermatozoon stainedfeebly except for a small portion at its junction with the tail (centrosome), whichstained deeply. The tail was always found to be well stained; its course ratherirregular; but never was it seen to change abruptly, as was commonly observedin the rabbit, nor did it ever extend in a direct course from the head, as is therule in man and in the horse.
