putrefactive bacteria entered tlie egg in its passage down 

 the oviduct and before the shell was formed. 



But to conclude that all eggs when laid contain putre- 

 factive bacteria is not warranted. It is a matter of com- 

 mon household observation that a few eggs do not decay, 

 no matter how long they may be kept, and the further 

 fact that eggs packed in some dry material, as sawdust, 

 salt, etc., and those greased or coated with gelatin, etc., 

 seem to keep longer than those left, in the open air, would 

 seem to indicate that the bacteria enter through the shell. 



I regret that these exi^eriments were not comijleted. 



The jjoint is one of considerable hygienic and even com- 

 mercial importance and one that needs but a little careful 

 work to settle beyond question.

Correlation of Tejon Deposits With Eocene Stages of the 

 Gulf Slope. 

 While comparing the Texan Eocene fossils with type 

 specimens and others in the collection of the U. S. 

 National Miiseum and in the Philadelphia Academy of 

 Natural Sciences I have been impressed with the remark- 

 able sameness in faunal characters throughout the vast 

 extent of the lower Claiborne, or Lisbon, horizon; many 

 of the species from South Carolina are identical with 

 those from the banks of the Eio Grande, and the rocks 

 from Ft. Tejon, California, furnish a very similar fauna 

 with several identical and many more analogous species. 

 Gabb's Cardita hornii is Venericardia iilanicosta Lam. as 

 held by Conrad; the type specimen is slightly malformed 

 and imperfect, but others from the same locality are quite 

 tyj)ical planicosta. Gabb's Architectonica cognata is Conrad's 

 Solarium alveatum; Gabb's Architectonica hornii, Conrad's 

 Solarium amcenum; Gabb's Neverita secta, Conrad's Natica 

 ostites, and so on. Gabb's peculiar and characteristic little 

 Whitneijaficus is known from Alum Creek Bluff, Colorado 



Eiver, Bastrop Co., Tex., and is in itself a strong argu- 

 ment for the synchrony of the Texan and California beds 

 from which it is derived. Moreover, in deposits of this 

 horizon on both sides of the Eockies, there are similar de- 

 velopments in the genera C'rassatella, Oytherea, I'yrula, 

 Lemfiisus, Bimella and others. 



With the above facts in mind I cannot help sug^estino- 

 that those who have an opportunity to study the Eocene 

 series of California (Tejon deposits) would do well to look 

 for the Midway stage which ranks second in persistency 

 among the subdivisions of the Eocene along the Gulf 

 slope. In other words search should be made along the 

 Chico-Tejon contact for such species as EncUmatoceras ul- 

 ricii, C'ucullcea macrodonta, Ostrea imlaakenda, to gethev with 

 varieties of Venericardia planicosta, Turritella mortoni, T. 

 humerosa, and other Midway forms.

An Addition to the Myology of the Cat. 



In St. George Mivart's book on the cat there is to be 

 found one of the most extensive articles on feline myology 

 ever written, nevertheless there seems to be a muscle in 

 the hind foot not mentioned in his work or anywhere else 

 as far as I can ascertain. It takes its origin by a broad 

 flat bundle of fibres from the outer side of the Os Calcis 

 immediately below the anterior prominence, these run 

 obliquely forwards forming a comparatively broad, thin 

 tendon, which blends on the plantar surface with, for the 

 most part, the Flexor-longus-pollicis, where it joins the 

 Flexor-longus-digitorum-pedis, but a few fibres of the 

 tendon go to the latter muscle. 



It is innovated by a branch from the external plantar. 

 That this muscle is not an abnormity I am quite sure as it 

 has been found in 2.5 subjects from the vicinity of New' 

 York and one from Italy. Joseph W. Thompson.

Drink. 



Horsford's Acid Phosphate 



with water and sugar only, 

 makes a delicious, healthful and 

 invigorating drink. 



Allays the thirst, aids diges- 

 tion, and relieves the lassitude 

 so common in midsummer. 



Dr, M. H. Henry, New York, says: 

 "When completely tired out by pro- 

 longed wakefulness and overwork, it is 

 of the greatest value to me. As a bev- 

 erage it possesses charms beyond any- 

 thing I know of in the form of medi- 

 cine."
