wolves. I have been getting capital material from India, 

 and working the whole affair out on the basis of measure- 

 ments of skulls and teeth. 



However, my paper for the Zoological Society is 

 finished, and I hope soon to send you a copy of it. ... 



Unfortunately he never found time to complete 

 his work for final publication in book form, and the 

 rough, unfinished notes are all that remain of his 

 work, beyond two monographs " On the Epipubis in 

 the Dog and Fox" (Proc. Roy. Soc. xxx. 162-63), and 

 "On the Cranial and Dental Characters of the 

 Canidae" (Proc. Zool Soc. 1880, pp. 238-288).

4 MARLBOROUGH PLACE, 

 Jan. 17, 1880. 



MY DEAR FLOWER I happened to get hold of two 

 foxes this week a fine dog fox and his vixen wife ; and 

 among other things, I have been looking up Cowper's 

 glands, the supposed absence of which in the dogs has 

 always "gone agin' me." Moreover, I have found them 

 (or their representatives) in the shape of two small sacs, 

 which open by conspicuous apertures into the urethra 

 immediately behind the bulb. If your Icticyon was a 

 male, I commend this point to your notice. 



Item If you have not already begun to macerate 

 him, do look for the "marsupial" fibro-cartilages, which 

 I have mentioned in my " Manual," but the existence of 

 which blasphemers have denied. I found them again at 

 once in both Mr. and Mrs. Vulpes. You spot them im- 

 mediately by the pectineus which is attached to them. 



The dog-fox's caecum is so different from the vixen's 

 that Gray would have made distinct genera of them. 

 Ever yours very faithfully, T. H. HUXLEY.
