cave surface at the base of each. Under ordinary circumstances the antlers would have been 

 retained until the end of April in the following year.

3562. The shed antlers of a castrated Fallow-deer (Cervus Dama). 



They are of diminutive size and abnormal form, and illustrate, by the excavation at their 

 base, the active absorbent process through which they were cast off. 



Presented by Sir Philip de Malpas Grey Egerton, Bart., M.P. 



3563. A shed left antler of a castrated Fallow-deer (Cervus Dama). 



The absorbent process by which it was undermined has extended above the level of the 

 burr as far as the base of the brow-snag. 



Presented by Sir Philip de Malpas Grey Egerton, Bart., M.P. 



3564. One of a pair of antlers that were put up by a castrated buck and retained. 



Both were small and unbranched, and showed the influence of the persistent vascular 

 periosteum and integument by the formation of several irregular tubercles of bone. 



Presented by Sir Philip de Malpas Grey Egerton, Bart., M.P. 



3565. A shed antler of stunted growth of a castrated Fallow-deer (Cervus Dama). 



The absorbent process has excavated the base of the antler and detached it from above the 

 level of the burr. 



Presented by Sir Philip de Malpas Grey Egerton, Bart., M.P. 



3566. The antlers of a castrated Fallow-deer eight years old. 



They were developed after castration, and were retained two years before the animal was 

 killed. 



Presented by Sir Philip de Malpas Grey Egerton, Bart., M.P. 



3567. The calvarium and antlers of a castrated Fallow-deer (Cervus Dama). 



The antlers were retained long after the usual period of shedding, and had become much 

 malformed by exostoses developed from the persistent periosteum. 



Presented by Sir Philip de Malpas Grey Egerton, Bart., M.P. 



3568. The cranium of a Fallow-deer (Cervus Dama), from which the left testis had 

 been removed, showing a corresponding arrest of development of the left 

 antler. 



The velvet was retained longer than usual on both antlers. The arteries have been injected, 

 showing the branch of the external carotid which passes over the zygoma and behind the 

 orbit for the supply of the periosteum and integument of the antlers. The calvarium has
